Part A. Classify the following reactions:
A. HNO3(aq) + NH3(aq) → NH4NO3(aq) + H2O(l)
B. 2 Cu(s) + O2(g) → 2 CuO(s)
C. NaCl(aq) + AgNO3(aq) → NaNO3(aq) + AgCl(s)
D. 2 LiOH(aq) + H2SO4(aq) → Li2SO4(aq) + 2 H2O(l)
E. CaCl2(aq) + K2CO3(aq) → 2 KCl(aq) + CaCO3(s)

Reactions in water solution can be classified based on the driving force that converts reactants to product. The three classes are precipitation reactions, acid-base neutralization reactions, and oxidation-reduction reactions.
• In precipitation reactions a solid product forms from aqueous reactants. The product can be predicted by using solubility rules.
• In acid-base neutralization reactions an acid (proton donor) reacts with a base (proton acceptor) to form an ionic salt and sometimes water. You can recognize this type of reaction by the presence of an acid and base in the reactants.
• In oxidation-reduction reactions (or redox for short) electrons are transferred between reactants. So you will always see changes in oxidation number within this type of reaction.
