Review-Chemical Reactions

Write balanced chemical equations for the following reactions:

a. chlorine gas and aqueous sodium iodide react to form aqueous sodium chloride and
solid iodine

b. solid sodium chlorate is heated to form solid sodium chloride and oxygen gas

c. solid potassium reacts with liquid water to produce aqueous potassium hydroxide and
hydrogen gas

Answer 1

a. Cl2 (g) + 2NaI (aq) → 2NaCl (aq) + I2 (s)

b. 2NaClO3 (s) → 2NaCl (s) + 3O2 (g)

c. 2K (s) + 2H2O (l) → 2KOH (aq) + H2 (g)
