You may find bellow the balanced chemical reactions.

Explanation:

a) Decomposition: 2 NaCl (s) → 2 Na (s) + Cl₂ (g)

b) Combination: 2 Ca (s) + Br₂ (g) → 2 CaBr (s)

c) Combustion: C₂H₄ (g) + 3 O₂ (g) → 2 CO₂ (g) + 2 H₂O (g)

d) Double replacement: FeCl₂ (aq) + 2 KOH (aq) → Fe(OH)₂ (s) + 2 KCl (aq)

where:

(s) - solid

(g) - gas

(aq) - aqueous
