CHEM 60 Quiz 7 (15 points)
Name _________________________________
1. (6 points) Write the full-formula, complete ionic, and net ionic equation (FFE, CIE, and NIE)
for each of the two reactions described below. In each equation, indicate physical state of
each reactant and product: (s), (l), (g), or (aq).
(a) Nitric acid is mixed with an aqueous solution of potassium hydrogen carbonate.
FFE: HNO3(aq) + KHCO3(aq) → KNO3(aq) + H2O(l) + CO2(g)
CIE: H+(aq) + NO3−(aq) + K+(aq) + HCO3−(aq) → K+(aq) + NO3−(aq) + H2O(l) + CO2(g)
NIE: H+(aq) + HCO3−(aq) → H2O(l) + CO2(g)
(b) Copper(II) oxide is added to chloric acid.
FFE: CuO(s) + 2 HClO3(aq) → Cu(ClO3)2(aq) + H2O(l)
CIE: CuO(s) + 2 H+(aq) + 2 ClO3−(aq) → Cu2+(aq) + 2 ClO3−(aq) + H2O(l)
NIE: CuO(s) + 2 H+(aq) → Cu2+(aq) + H2O(l)
