Chemical Reactions Homework Problem Set

This problem set was developed by S.E. Van Bramer for Chemistry 145 at Widener University.

  1. Balance the following equations. Give the names of the reactants and the products:
    1. LiOH (s) + H2SO4 (aq) --> H2O (l) + Li2SO4 (aq)
    2. Mg(OH)2 (aq) + H3PO4 (l) --> Mg3(PO4)2 (aq) + H2O (l)
    3. CH4 (g) + O2 (g) --> CO2 (g) + H2O (g)
    4. C8H18 (l) + O2 (g) --> CO2 (g) + H2O (g)
    5. NaCl (aq) + AgNO3 (aq) --> AgCl (s) + NaNO3 (aq)
    6. CH3COOH (aq) + NaHCO3 (s) --> CO2 (g) + H2O (l) + NaCH3COO (aq)

  2. Balance the following equations. Determine the molecular formula and the molecular weight of each species.
    1. Nitrogen monoxide reacts with ozone (trioxide) to produce nitrogen dioxide and oxygen molecules.
    2. Iron (III) oxide reacts with zinc metal to produce iron metal and zinc (II) oxide.
    3. Hydrobromic acid reacts with aluminum metal to produce hydrogen gas and aluminum bromide.
