Precipitate in Chemistry - Learn About the Properties of a Reaction

Precipitate in Chemistry - Learn About the Properties of a ReactionAre you aware of the properties of precipitate in chemistry? If not, it is a key concept in the study of reaction mechanics. It provides an analytical method to analyze the mechanical behavior of chemical compounds.In this process, a reaction between two different components of a material is induced. First the reaction can be between one chemical component and another. The properties of the reaction are found based on the properties of the two components. For example, hydrogen and oxygen react with each other in various chemical reactions. The properties of the reaction depend on the type of the atoms that are present in the two components.Precipitate in chemistry is the analytical method of determining the relationship between the two components and the properties of the reactants. This is very important to the understanding of the behavior of chemical compounds. You can also use this as a guide in your research work . The test results are very important for any scientist to study the relationship between the properties of the reactants and the properties of the precursors.The test procedure will include the precipitation of a sample. The test is done by compressing the sample at a particular rate of pressure. The test is also done on a rotating drum in which the reaction is induced by the compressed sample.The test results are very useful for the scientists. To find out the reaction between the sample and the precursors, you need to know the properties of the sample. As the substance is compressed, the change in its properties will be observable.Precipitate in chemistry is an analytical tool. However, in the past, the approach was very limited. Nowadays, we have better and advanced analytical techniques. The analysis of a mixture of products helps to determine the properties of the reactants.The properties of the reactants can be determined by varying the amount of reactants. Another important factor that can be used in this process is the ratio of reactants to precursors. The importance of this process is that it allows the scientists to study the behavior of the reactants in a system of their own systems.The reactants can be prepared either naturally or artificially. Some reactants are prepared from common elements like carbon, nitrogen, and hydrogen. Other may be prepared from materials like clay, sulfate, or seawater.

Chemistry Tutors Can Give Students a Great Education

Chemistry Tutors Can Give Students a Great EducationThe field of Chemistry is one of the few that require a tutor to supplement the basic schooling in the subject. A tutor is someone who goes through the whole learning process from pre-school education, through the grades, on up to college level. At this level of the study, the tutor is also concerned with the practical side of learning such as studying and working at home.The tuition in Chemistry can be given at the elementary school level or even higher if one is confident in handling the principles of Chemistry. One can actually start off as a teacher, but then, he or she may want to step out on his or her own. He or she can go to college, but if that does not appeal to him or her, he or she can simply volunteer at a local college to get a job as a tutor.For those who are not willing to undergo a rigorous program, they can take on the subject as a hobby and just learn the technical aspects of the science. This can be done through books or online resources. There are online resources that are specially designed for those who want to take up Chemistry at a higher level. Such resources are available online in the form of video clips, audio, and graphics.These will provide information about different types of materials that are used for Chemistry. They have video tutorials, audio interviews with experts, and interactive sessions. These are easily accessible to anyone who has access to the internet.If one has the right guidance, he or she can become a tutor in Chemistry. The tuition will focus more on the practical aspect, which is what the tutor is responsible for. It is important that the tutor has the necessary knowledge, skills, and background in Chemistry to do this.The person who is going to be the tutor should have all the necessary qualifications and even certifications before he or she can start working as a tutor. Most tutors are called upon to help out other students who want to take up a subject like Chemistry. If there is someone who would like to teach Chemistry and has the appropriate background, then a good opportunity is available for him or her. These are usually provided by the college or university and that is the best place where a student can obtain such tutoring.As the area of Chemistry is also a science, it is important that the student knows how to do and research with the right resources. A good tutor will do all these things, no matter what is the knowledge level of the student.

Ask an MBA Admissions Expert Dan Bauer

Ask an MBA Admissions Expert Dan Bauer Varsity Tutors brings you insider tips and advice straight from nationally recognized admissions experts. Having founded his admissions consulting firm, The MBA Exchange, in 1996 after serving as an admissions interviewer for his alma mater HarvardBusiness School, Dan Bauer and his firm have helped over 3,000 individuals gain acceptance from the worlds most selective MBA programs. Read on for the valuable advice he has to offer about the business school admissions process. VT: How much time should be set aside to adequately prepare for and complete the application for an MBA program? Dan: Depending on the candidacy, this can take anywhere from several weeks to several months to prepare applications. However, the start of the process is not writing essays, but rather optimizing the candidacy itself. The professional, academic and personal aspects of the individuals profile need to be analyzed so that the applicant can leverage strengths and mitigate vulnerabilities. If done properly, this front-end effort brings focus, momentum and efficiency to preparing the actual applications. A smart way to get started is with a free, expert evaluation of the candidacy from a knowledgeable admissions consulting firm. VT: What would you say is the single most important thing to focus on for this kind of application? Dan: Most importantly, a truly competitive application must present a combination of three elements: qualifications, motivation and contributions. First, the candidate needs to convey an academic and professional background that ensures competence in the MBA classroom. Second, the applicant must illustrate a clear rationale and sincere passion for attending the targeted school as the bridge to post-MBA goals. And finally, he or she should make a compelling case for the value added that the candidacy will bring to the program and its participants, before and after graduation. VT: What do MBA admissions officers look for most in the essay questions? Dan: Relevance, initiative and authenticity. Simply stated, the applicant needs to answer the essay questions as posed by the school. However, in doing so, the admissions staff is not satisfied with mere facts or boilerplate. Rather, they want the candidate to grasp address the issues behind the question just as a leader does in the business world -- so the essay is robust and distinctive. Finally, they want insight into the thoughts, feelings and values of the applicant in order to know the candidate even before they meet him or her in-person. VT: What are the biggest mistakes one can make on this application? Dan: The biggest error is presenting only what the applicant thinks the admissions committee wants to see. Some individuals mistakenly believe that there is no need to go beneath the surface or beyond the resume. However, developing a candidacy and crafting an application are intensely personal. Through this process, the candidate learns a great deal about himself or herself. In fact, this may be the first and last time in their lives that they do such a thorough assessment of their past, present and future. It is only such a journey of self-discovery that ultimately produces MBA applications that are cathartic for the candidate and compelling for the adcom. There are no magic bullets, insider tips or expedient shortcuts to getting there. VT: What aspects of the MBA admissions process make it most different from undergraduate admissions process? Dan: The admissions process at top-tier business schools is more comprehensive and subjective than that at leading undergrad and other graduate schools. When applying to non-MBA programs, it can be nearly impossible for someone to overcome a sub-par GPA and/or standardized admissions test. In contrast, graduate business schools carefully consider the 2+ years of full-time work experience that most applicants have completed. Furthermore, most non-MBA programs ask only one essay question with a broad topic (e.g., a personal statement) and have no required interview. With the business school application process, there are typically several essays and a mandatory interview before admission is granted. So, by comparison, the MBA applicant has a significantly greater opportunity to define the candidacy and convince the school to grant acceptance. VT: Is there anything that automatically disqualifies an applicant from being considered for an MBA program (i.e. low GPA, lack of particular work experience, etc.)? Dan: No. Having helped hundreds of MBA applicants to gain admission to their targeted b-schools despite significant academic, personal or professional constraints, it is clear that admissions committees evaluate each candidacy in totality. A weakness in one area can be neutralized by strength in another. Never say never! For instance, my firm has guided five past clients to acceptance at top-10 business schools even though these individuals did not have undergraduate degrees! VT: What kind of work experiences should be highlighted in the MBA application? Dan: Published statistics confirm that top business schools favor applicants from the leading financial and management consulting firms. However, the admissions committees also want professional diversity in their incoming class. What is most important is not the specific industry or job function of the MBA applicant, but rather the growth, learning and impact that the applicant has acquired and will share with classmates. Being an overachiever with a passion for advancing the knowledge of others can transcend any specific employment profile. VT: What advice do you have regarding GMAT test prep? Dan: Be very thoughtful in choosing the tutoring resources that you engage for test prep. One size does not fit all. That is why my firm The MBA Exchange does not offer GMAT tutoring directly but rather provides a free evaluation of prep needs and introduces several specialists to each client. To determine the best resource, consider which components of the test require the most study and support, and confirm the tutors qualifications in that area. Then, think about how you learn most effectively (e.g. in-person vs. remote; individual vs. group, etc.) and make sure the tutors services are a match. Finally, allow yourself abundant time to learn and practice before you take the actual test; only when you and your tutor agree that your practice scores have reached an acceptable peak should you schedule the real GMAT. VT: Is it absolutely necessary to have work experience prior to starting an MBA degree? Dan: There are some exceptions, but for the vast majority of applicants having 2 more years of full-time work experience prior to applying is a must. Not only is this an expectation of the admissions committee, but this background also ensures that the candidate will gain more from and contribute more to the MBA education. The currency of business school classrooms especially those where the case study method is king -- is the professional background that each student brings. Both faculty and peers assume that on day one everyone has a solid grasp of the nomenclature, culture and nuances of the business world. This provides a shared platform for learning, growing and bonding. VT: What are the characteristics of a great MBA program? Dan: Believing that there are several excellent business schools for every applicant to consider, I am going to answer with a list of selection criteria. A great MBA program offers knowledge and perspective that align seamlessly with the applicants vision. Professors who are recognized inside and outside the school as thought leaders in their respective disciplines. A dynamic culture where students are the program owners and customers. Loyal, global alumni actively involved with the school and dedicated to helping each other succeed. A productive and responsive career services staff. Recruitment by industry-leading companies that offer real jobs, even during tough economic times. And finally, a respected and recognized brand, transcending time and borders, that graduates can count on as a lifetime asset.

Van Gogh, Cézanne, Pissarro, Auguste Renoir, Joseph Durand-Ruel, Jean-Frédéric Bazille, Manet, Berthe Morisot, Degas, Ingres, Delacroix, and Warhol all appear at the MET, an out-of-the-ordinary art museum in the United States of America.The greatest artistic movements are all present at the MET: im pressionism, realism, self-portraits, expressionism, fauvism, naturalism, pointillism, and symbolism.In this article, we've put together a non-exhaustive list of some of the best paintings you can see in the Metropolitan Museum of Art in New York.Aristotle with a Bust of Homer by RembrandtRembrandt needs no introduction; he’s one of the most famous painters in the world and a Dutch baroque master.A philosopher thinking about a philosopher. (Source: Wikimedia Commons)His work appears in the world’s greatest museums including his piece Aristotle with a Bust of Homer in the MET. In this piece, you can see Aristotle dressed in 17th-century attire and posing with a bust of the poet Homer.It symbolises that philosophy comes before poetry and art in general. Thus, Aristotle is inspired by the poet. The political aspect is also represented by the portrait of Alexander on Aristotle’s medallion.The piece was acquired by the MET in 1961 for the modest sum of 2.3 million dollars.The Music ians by CaravaggioThe Musicians or Concert of Youths is an oil on canvas from the Italian baroque master Michelangelo Merisi da Caravaggio. As a naturalist, realist, and great user of chiaroscuro, Caravaggio is famous for this huge work.The Musicians can be seen at the MET and includes several musicians and cupid on the left. It’s possible that the person in the background is Caravaggio, making this one of the artist’s first self-portraits.The theme of mythology and Bacchus is present in Caravaggio’s work and in pieces that can be found in New York, France, Italy, England, and Spain.Woman with a Water Jug by Johannes VermeerVermeer, the Dutch Baroque  painter, is most famous for his pieces like The Milkmaid or Girl with a Pearl Earring. Vermeer, much like Rembrandt, is considered a master of the Dutch Golden Age.Vermeer is a baroque master. (Source: Wikimedia Commons)The piece Woman with a Water Jug, painted in 1658, depicts a young working-class woman carrying a water jug wit h one hand and opening a window with the other.Like in other pieces, Vermeer painted a preoccupied woman contrasting the freedom of outside with the traditional rules inside.Autumn Rhythm (Number 30) by Jackson PollockAutumn Rhythm (Number 30), is an enamel paint on canvas by Jackson Pollock, an American abstract expressionist painter. This influential contemporary artist created over 700 pieces!Here are some of his other great works:Untitled (Naked Man with Knife), 1938-1940Mural, 1943Number 5, 1948One: Number 31, 1950Number 1 (Lavender Mist), 1950Blue Poles: Number 11, 1952Convergence, 1952The Deep, 1953White Light, 1954While the technique used to create his works is often focused on, Autumn Rhythm seems to express anger. Of course, you can come to your own conclusions on this beautiful and original piece.We could also have mentioned the other artists on display in the MET like Gauguin, Kandinsky, Caillebotte, Sisley, Corot, Géricault, Seurat, or even Watteau.

The teachers at school do not provide that much care and attention to each student and thus kids lack from some good way of education. School administration is also now a days not conscious about how to deal with a kid so that they even fall to impress the child to learn more. A good tutor is very important for those kids who have a set of working parents. A good teacher can help you get the real meaning of life. The teacher can even make you aware of everything that life offers. From the very initial days it is important that a child should be under good guidance that can only be possible with the help of parents and a good tutor. Then only can a child learn and inculcate some of the best qualities within them. But where will you find a good teacher who will provide you the basic guidance of life as well as help your child to learn the academic subject in a better way. Sending your kid to any tutor is also time taking and in some cases risky as well. The moving here and there is time taking and also not of so much worth as teachers are sometimes average. For kids it is not possible to judge a teacher as they are small enough to judge between what is good and what is bad. Private teachers in many cases take this advantage and so kids are left with average level teaching. But as parents you have to find a proper teacher for your little one. But how will you find. Online teachers are available with ease. Online teachers are a good way through which kids can learn better and faster. Today with the reach of internet, the availability of such type of services have reached to a high level.   Every single person is getting involved with such types of services.

The completion of the motto is the main thing. The interview process of any teacher for any of the service is very tough and thus the end result comes out to be the best. While the teacher for the kids section are much more patient and can handle the students with much efficiency. Small kids require immense amount of time to learn anything as everything is new to them and so adapting everything takes time. The online tutoring process does not have any kind of time limitation and so kids can take their won time and learn the entire thing. Even in many cases parents can also accompany their child while the classes are on and even learn themselves. This helps the parents also in many ways. They get to learn and spend time with their kids while attending the classes. Kids can afterwards take help from their parents as well to adapt any new topic which they are unable to do. The facility of one-on-one service is also available with online tutors. In this facility the student is accustomed with a single teacher and no other students are allowed in this class. It is a very unique class and so any student who is very weak can avail this type of class. Such type of class helps in making the student or kid learn more and in a better way.

Scatter Plots Worksheets

Scatter Plots Worksheets Definition: - A plot or graph of the pairs of data from a simple regression analysis. Example: An insurance company wants to know how the amount of life insurance depends on the income of persons. The researcher department at the company collected information on six persons. The following table lists the annual incomes (in thousands of dollars) and amounts (in thousands of dollars) of life insurance policies for these six persons. Annual income 62 78 41 53 85 34 Life insurance 250 300 100 150 500 75 Construct a scatter plot for the above data. Solution: - A scatter diagram is helpful in detecting a relationship between two variables. For example, by looking at the below scatter diagram, we can observe that there exists a strong relationship between annual income and food expenditure. If a straight line is drawn through the points, the points will be scattered closely around the line. Example: - The owner of Reds Towing and Garage service is interested in finding the relationship between the lowest temperature on a winter day and the number of emergency road service calls his shop receives. The following table gives the lowest temperature (in degree Fahrenheit) on seven winter days and the number of emergency road service calls received on those days. Lowest temperature 15 0 24 -10 30 9 36 Number of calls 12 22 16 31 7 24 6

Why College Tuition Is Increasing

Why College Tuition Is Increasing The average tuition for the top 10 colleges has increased around 25% the last six years, starting with the 2004-2005 school year through the 2009-2010 school year. Also, these tuition costs do not include room and board, meal plans, books, other mandatory fees, etc. These are simply base tuition numbers, and tuition can increase or decrease depending on the major within a university. This can vary dramatically from university-to-university. One of the biggest reasons listed is that states have stopped or reduced spending on public universities, thus tuition has increased. Most state governments control the tuition levels. Also, private colleges can receive some state funding and can be affected be lack of funding. Professors at elite colleges are experts and competition in the profession has continually increased. Furthermore, these elite colleges are in intense competition with one another to hire the best professors. Competition naturally increases a professors salary, which increases the universitys tuition. Also, lately elite colleges have been attracting expert professor overseas. Essentially, some professors could be considered priceless to some colleges; however, it will be the student funding it, according to an article in the U.S. News and World Report. The article also reported that new technology can become very expensive for universities, especially the elite ones that are willing to fund the best technological resources. Universities want to provide students with the most up-to-date equipment in libraries, labs and throughout the college. This technology can be extremely expensive; however, these colleges believe that it is vital to meet the demands of current and future students. Government regulation has increased across both federal and state levels. Colleges have been affected by this because they have to hire people to operate these regulations because a lot of colleges are regulated by the federal government. More university employees eventually results in an increase in student tuition, in order to cover staff salaries. The U.S. News and World Report reported that colleges can be intensely affected by the economy. Colleges are very energy intensive, and as energy costs rise, colleges spending increases. This will increase tuition. Also, as the economy drops, a universitys endowments and donations will sharply decrease. Elite colleges depend on large donations, and without them, students will be picking up the fiscal slack. Essentially, colleges compete with one another to have the best facilities, technology, equipment and professors. The top 10 colleges are in extreme competition with others to be the best, and these colleges are willing to pay whatever that may cost. Also, a lot of these elite colleges believe that a prospective student will not pass up the opportunity to attend an elite university. Recently interest for top colleges has soared as colleges have been receiving record numbers of applications. This could be another factor for increasing tuition because more prospective students are willing to pay high tuition.
