(a) Balanced equation for the decomposition of solid potassium chlorate:

2KClO3(s) -> 2KCl(s) + 3O2(g)

(b) Balanced equation for the reaction between solid aluminum and diatomic iodine:

2Al(s) + 3I2(s) -> Al2I6(s)

(c) Balanced equation for the reaction between solid sodium chloride and aqueous sulfuric acid:

2NaCl(s) + H2SO4(aq) -> 2HCl(g) + Na2SO4(aq)

(d) Balanced equation for the reaction between phosphoric acid and potassium hydroxide:

H3PO4(aq) + 3KOH(aq) -> K3PO4(aq) + 3H2O(l)
