Chem 171 Quiz 5 Version A (5 pts each) (Show work, unit, sig fig for full credit) Name (NIE/Metal Key) Sec 1. Does a reaction occur when PbCO 3 is mixed with CH 3 COOH? If a reaction occurs, show the molecular equation, the total ionic equation and the net ionic equation. Show the phases. Identify any spectator ions if present. Yes a reaction occurs, the PbCO 3 dissolves. PbCO 3 (s) + 2CH 3 COOH (aq) Pb(CH 3 COO) 2 (aq) + CO 2 (g) + H 2 O(l) (Molecular Equation) PbCO 3 (s) + 2CH 3 COOH (aq) Pb 2+ (aq) + 2CH 3 COO - (aq) + CO 2 (g) + H 2 O(l) (Complete Ionic Equation) Net Ionic Equation is the same as the Complete Ionic Equation No Spectator Ion 2. What is meant by “reactivity of a metal”? Describe the chemical reaction. Reactivity of a metal with hydrochloric acid is the measure of the metal undergoing a redox reaction 1)by reducing H + to H 2 (g) 2) and the metal itself being oxidized to M n+ Chem 171 Quiz 5 Version B (5 pts each) (Show work, unit, sig fig for full credit) Name Sec 1.
