Question

Balance the chemical equation by including the physical states of the substames for the following reactions.

a) Barium chloride and sodium sulphate aqueous solutions react to give insoluble Barium sulphate and aqueous solution of sodium chloride.
b) Sodium hydroxide reacts with hydrochloric acid to produce sodium chloride and water.
c) Zinc pieces react with dilute hydrochloric acid to liberate hydrogen gas and foms zinc chloride

Answer 1

hope it helps you

Answer 2

Ans:

a)Barium chloride and sodium sulphate aqueous

solutions react to give insoluble Barium sulphate and

aqueous solution of sodium chloride.

Sodium sulphate + Barium chloride Barium sulphate + Sodium chloride

Na2SO4(aq) + BaCl2 (aq) BaSO4 (s)+ NaCl(aq)

b) Sodium hydroxide reacts with hydrochloric acid to

produce sodium chloride and water.

Sodium hydroxide + Hydrochloric acid Sodium chloride + Water

NaOH(aq) + HCl (aq) NaCl(aq) + H2O(l)

c) Zinc pieces react with dilute hydrochloric acid to

liberate hydrogen gas and forms zinc chloride.

Zinc+ dil. hydrochloric acid Zinc chloride + Hydrogen gas

Zn(s) + dil.HCl (aq) ZnCl2(aq) + H2(g)
