Page 1 of 2 Pre-lab Questions for Experiment #4 Chemical Reactions 1) A chemical equation uses chemical symbols to show what happens during a chemical reaction: reactants → products. A chemical equation is a shorthand notation of a chemical reaction. Once the reactants and products are known, then we can balance the chemical equation by the Law of Conservation of Mass. Balance the following chemical equations: (a) Nalico, Na.co, + H2O + CO. (b) Cu + HNO, Cu(NO) + NO...
