Answer 2

Here are your answers

1. Zinc + hydrochloric acid = Zinc Chloride + Hydrogen gas.

Reaction :
Zn + 2HCl = ZnCl + H2


2. Sodium hydroxide + Hydrochloric acid = Sodium chloride + Water

Reaction : NaOH + HCl = NaCl + H2O


3.Calcium hydroxide + sulphuric acid = Calcium sulphate + Water

Reaction : Ca(OH)2 + H2SO4 = CaSO4 + 2H2O
