Cam was absent. An assignment was e mailed to his house for him to do work at home.
introduction to the early atomic theory starting with Democritus about 2000 years ago Discuss his theory of the atom as being invisible, indivisible and the smallest unit which makes up matter. Discuss how that theory relates to today's atomic theory. Discuss some later atomic theories including the chocolate chip model
Use measurement of the amounts mass before and after a reaction. Present the reaction which shows the decomposition of mercury oxide by heat. Write the correct formula for all participants, and determine the reactants and the products. Show how the equation can be written in both directions.. Insert the masses for the reactant and for one of the products, mercury. Elicit how to determine the mass of the second product, Oxygen. Have a correct algebraic equations set up to solve for X. Present a second reaction regarding carbon dioxide, carbon monoxide and oxygen. Present masses for 2 of the substances and determine the unknown mass.
Elicit and state the law of Conservation of Matter.
Define using examples what is a chemical polymer. Differentiate between natural and synthesized polymers. Present formulas for some common polymers, like Bakerlite, Rayon, and cellulose. Discuss some common uses. Introduce polyethylene, polystyrene, and poyvinyl chloride.

Joshua worked long and hard preparing for his exam. I am extremely proud of his work ethic, ability to ask very relevant questions, and keep me constantly thinking.
Introduce natural and synthetic polymers. Define both and define polymer. Discuss proteins and nucleic acids as naturally occurring polymers, with molecular masses in the millions. Present some recently developed artificial polymers, along with their structural formulas, common names and uses. Elicit how how to identify the structural formulas.
Outline and discuss the formation of plutonium from neutron bombardment of uranium. Outline and discuss all the steps which involve beta emission and neutron bombardment which culminate in the formation of the plutonium nucleus. Discuss the toxicity of plutonium.
Discuss esterification. Use formulas of organic acids and alcohols to depict how an ester is formed by dehydration. Introduce the general formula and highlight that the oxygen atom between the alcohol and the acid is part of the alcohol moiety. Use examples of esters to indicate the nomenclature. Introduce salts of esters formed by reactions with sodium hydroxide. Discuss and show examples of esters which are used in food and drinks and are listed as artificial taste ingredients. Discuss and show synthesis of oil of wintergreen which is methyl salicylate.
From a sketch of the structural formula for salicylic acid and acetic anhydride, write the synthesis for the product acetyl salicylic acid, which is aspirin. Discuss how when the product decomposes with moisture, acetic acid is released, which is vinegar. Determine that the smell of vinegar when a bottle of aspirin is opened indicates that the aspirin is decomposing and not up to strength. Draw the structural formula for N-acetyl para amino acid, which is acetaminophen (Tylenol). Note the structural likeness and discuss why both are analgesics. Introduce amides , their general formula and resonance atoms.
