CHEM 1A Chapter Notes - Chapter 4: Solution, Limiting Reagent, Titration
Document Summary
Chapter 4 - chemical quantities and aqueous reactions (pp. Climate change and the combustion of fossil fuels (p. 139) Reaction stoichiometry: how much carbon dioxide? (p. 140) Limiting reactant, theoretical yield, and percent yield (p. 145) Types of aqueous solutions and solubility (p. 158) Representing aqueous reactions: molecular, ionic, and complete ionic equations (p. 166) Key concepts: climate change and the combustion of fossil fuels (4. 1) Greenhouse gases warm earth by trapping some of the sunlight that penetrates earth"s atmosphere. Global warming, resulting from rising atmospheric carbon dioxide levels, is potentially harmful. The largest atmospheric carbon dioxide source is the burning of fossil fuels. This can be verified by reaction stoichiometry: reaction stoichiometry (4. 2) Reaction stoichiometry refers to the numerical relationships between the reactants and products in a balanced chemical equation. When a chemical reaction actually occurs, the reactants are usually not present in the exact stoichiometric ratios specified by the balanced chemical equation.
