Answer 1

Answer:

2. Write the balanced equation for the following chemical reactions.

(a) Hydrogen + Chlorine → Hydrogen chloride

(b) Barium chloride + Aluminium sulphate → Barium sulphate + Aluminium chloride

(c) Sodium + Water → Sodium hydroxide + Hydrogen

Ans: (a) H2 (g) + Cl2 (g) → 2HCl (g)

(b) 3BaCl2 (s) + Al2(SO4)3 (s) → 3BaSO4(s) + 2AlCl3 (s)

(c) (c) 2Na(s) + 2H2O (l) → 2NaOH (aq) + H2 (g)
