Chapter 1 Carbon Compounds and Chemical Bonds. (Covered material: 1.1 - 1.8; 1.12 - 1.17) 1. Structural Theory – most fundamental theory of Organic Chemistry (developed independently by A. Kekule‚ A. Couper and A. Butlerov between 1858 and 1861). Organic Compounds – compounds of carbon and hydrogen. Other elements frequently found in organic compounds are: oxygen‚ nitrogen and halogens (F‚ Cl‚ Br‚ I); less frequently found are: sulfur and phosphorus. Review Periodic Table for determining valence

Organic Compounds Marilena Tagritzis 11-A Mr. Daniel Chemistry May 10‚ 2011 Organic Compounds An organic compound belongs to gaseous‚ liquid‚ or solid chemical compounds whose molecules contain carbon. Some types of carbon that contain compounds such as carbides‚ carbonates‚ and oxides of carbon and cyanides are sometimes classified as inorganic.

Abstract: When ionic compounds are dissolved in water‚ they break apart into ions. In this lab the opportunity to mix two ionic solutions and observe the results was given. Some ions will remain dissolved and uncombined in the solution even when they are mixed with other ions. When other ions are mixed‚ they form compounds that appear as cloudy or grainy precipitates. The objective of this lab was to observe the formation of compounds and to write the names and formulas of ionic compounds. It is also to

Experiment 1: Observations of Chemical Changes Lab Partners: None Date of Experiment: February 25‚ 2015 Location: My House Abstract: The experiment intended to provide observations of chemical changes as the primary objective. The experiment was divided into two parts‚ first‚ mixing two aqueous solutions of ionic compounds. The second part involved the observance of heating and combustion reactions‚ using the supplied solid elements and compounds. Experiment and Observations: The first part of

Personal Care period 4 Michelle Manobanda 2012 The FDA permits the use of mercury compounds in eye makeup at concentrations up to 65 parts per million. The preservative thimerosol‚ found in some mascaras‚ is a mercury-containing product. Mercury is associated with a host of health concerns including allergic reactions‚ skin irritation‚ toxicity‚ neurological damage‚ bioacculumation‚ and environmental damage. Mercury readily passes into the body through the skin‚ so normal use of the product

There are different types of Compound Interest. Interest is the amount of money earned in a saving account. * Simple Interest: Interest calculated once on the principal. * Compound Interest: Interest calculated for a given segment of time of the investment. For example‚ compounded monthly‚ means the interest is calculated each month and combined with the principal. So‚ for the next month‚ interest is earned on the interest. Continuously Compound Interest Formula P: ending

theoretical chemical equations of ionic compounds were balanced by the group to determine ratios of reactants and products. The products were determined by the group through switching the cation with their anion partner. Using this information‚ it was determined by the group‚ whether the reaction should result in a solid‚ gas‚ or water based on theoretical solubility. Then several experiments testing the reaction of these ionic compounds were performed by the partners. Two ionic compounds were mixed
