Drinking Water Chemistry - Understanding Nitrates and Nitrites

Drinking Water Chemistry - Understanding Nitrates and NitritesIn the realm of drinking water, we have nitrates and nitrites. And they're just one of the many essential nutrients in the water supply. But with water that is artificially treated it is very different. What you're drinking from a hosepipe may not be the cleanest water out there.Nitrates and nitrites are compounds that occur naturally in soil and plants. It has even been found in many non-organic fruits and vegetables. The key here is that when you eat foods that have been grown in areas where you're subject to a soil that is conducive to the growth of these nitrates and nitrites you are eating a lot of nitrates and nitrites. It's part of a natural process of growth in those soils.Nitrates and nitrites can be present at higher levels in some well treated water sources, such as some municipal supply systems. These sources are able to get rid of the nitrates and nitrites in a process called desalination. That process removes the chloride and sodium from the water. Chloride and sodium are both necessary elements for healthy water. But without them, the other components in your water would not function correctly.The major benefit to having water that has been treated this way is that it is a lot safer than tap water. Of course, you could also worry about how much of this chemical you're getting every time you drink from a hosepipe.So what can you do? If you're a regular home user of bottled water or some other source, you need to check with your local governing body to see if your water comes from a well. You may be able to switch your source over to something that is treated in a different way. Some water providers may offer it.If you're already drinking tap water, you may want to find out if the nitrate removal process is occurring in your city or area. Ask your local health department, school board, or water utility.We've talked about a few different examples of chemistry class, but the important thin g to remember is that we are all dealing with the same basic elements, water and oxygen. There are no 'dietary' guidelines for drinking water, so it's important to learn how to understand it in terms of your own body. And that goes beyond knowing how many nutrients to eat.

2019 American Education Week

2019 American Education Week The week before Thanksgiving, on November 18, 2019, American Education Week will kick off. Created by the National Education Association (NEA), this weeklong celebration of public education honors the professionals who make a difference in ensuring that every child in the country receives a quality educationfrom teachers to support staff, from communities to principals. Communities around the country can celebrate the daily components of American Education Week as scheduled below: Monday, November 18: Kickoff Day The nationwide kickoff, with activities and events at schools around the country. Tuesday, November 19: Parents Day A day for parents and/or other family members to join their children at school for a first-hand look at a typical school day. Wednesday, November 20: Education Support Professionals Day A day to honor the contributions of public support staff, such as instructional assistants, office workers, paraeducators, bus drivers, custodians, and security guards. Thursday, November 21: Educator for a Day A program in which community members are invited to school as guest educators. This day gives them the opportunity to get a feel for a typical school day, including everything from teaching classes to eating lunch in the cafeteria. Friday, November 22: Substitute Educators Day A day that honors the professional substitute educators who run classes when regular educators are absent. American Education Week was founded in 1921 by the National Education Association and the American Legion as a national effort to raise public awareness of the importance of education. The week-long celebration is now co-sponsored by several other organizations as well, including the U.S. Department of Education, the National School Boards Association, the American Federation of Teachers and the American School Counselor Association, among others. Public schools are continually working to be better and to keep pace with the ever-changing worldand prepare students for that world, says Eileen Huntington of Huntington Learning Center. Public schools are open to all, and are worthy of celebration. American Education week recognizes the many people who contribute to educating our nations children. As part of that group, we at Huntington Learning Center are so thankful for our colleagues and communities for all that they do to support students academic achievements and give all children a quality education.

The Study Of Acid Chemistry

The Study Of Acid ChemistryAcid Chemistry is the study of chemical reactions that take place when one substance interacts with another substance. It can involve many things like acids and bases, acids and bases. The basic definitions of acids and bases are quite similar, but the focus varies from one source to another.Acid Chemistry is an interdisciplinary subject which involves the study of reaction systems and their reactions with other substances. In this subject one learns about the phenomena of chemical reactions. These reactions can involve a wide range of activities such as reactions that modify a substance into a new substance, chemical changes between two substances, reactions that alter a compound from one form to another and reactions that result in a solid or liquid from a gas or vapour. A broad range of chemicals, both organic and inorganic, is included within the scope of this subject.Acid Chemistry involves the study of different kinds of reactions that take place at a molecular level. These reactions are classified as either a) internal or b) external. Internal reactions are mainly internal reactions where the substance is in contact with a different chemical form. External reactions are usually chemical reactions that take place on the surface of a substance where a new substance is formed.Chemical reactions involving the production of a product from a chemical precursor are called reactions that produce products. This is a very broad category of reactions that includes reaction where a chemical entity or a compound has its chemical activity determined by its chemical environment. These include reaction where a compound or an organic component is active in solution through a change in solute concentrations. Other examples include reactions where an organic material reacts with a non-organic material.Acid Chemistry involves both inorganic and organic chemical reactions. Inorganic chemical reactions are ones where a reaction occurs by splitting a part of a metal into an element and its chemical properties. Organic chemical reactions are ones where chemical entities undergo oxidation, reduction, crystallization and polymerization.Tacid chemistry Acid Chemistry can be studied at a variety of levels depending on the objectives of the student. For those who want to specialize in the study of reactions, there are institutes where students can take the courses required for their specific goal.Acid Chemistry also involves working on cross-disciplinary projects with a professor who is also involved in the research work. Some students are studying the chemistry of elements and how they react to each other and others are studying the chemistry of molecules that have been under modified conditions so that it can interact with another element.

Volume of a Cone Equation Tutors

Volume of a Cone Equation Tutors A cone is a solid geometric figure consisting of a circular base and a vertex at its top. The circular base is connected to the vertex by forming a curved surface around the cone. The circular base consists of the radius and the line joining the center of the circle to the vertex is known as the height of the cone. The volume of a cone equation is given as one-third the product of the area of the base circle and the height of the cone. Example 1: What is the volume of the cone whose height is 10m and the radius of its circular base is 6m? Given: radius, r = 6m Height of the cone, h = 10m Volume of the cone, V = 1/3 * * r2 * h This gives: Volume of the cone, V = 1/3 * * 62 * 10 = 120 * = 377m3 Therefore, thevolume of the given cone is 377m3 Example 2: What is the volume of the cone whose height is 5m and the radius of its circular base is 9m? Given: radius, r = 9m Height of the cone, h = 5m Volume of the cone, V = 1/3 * * r2 * h This gives: Volume of the cone, V = 1/3 * * 92 * 5 = 135 * = 424.1m3 Therefore, thevolume of the given cone is 424.1m3
