Question.
Write the balanced chemical equations for the following reactions.
(a) Calcium hydroxide $+$ Carbon dioxide $\rightarrow$ Calcium carbonate $+$ Water
(b) Zinc $+$ Silver nitrate $\rightarrow$ Zinc nitrate $+$ Silver
(c) Aluminium $+$ Copper chloride $\rightarrow$ Aluminium chloride $+$ Copper
(d) Barium chloride $+$ Potassium sulphate $\rightarrow$ Barium sulphate $+$ Potassium chloride

(b) Zinc $+$ Silver nitrate $\rightarrow$ Zinc nitrate $+$ Silver
(c) Aluminium $+$ Copper chloride $\rightarrow$ Aluminium chloride $+$ Copper
(d) Barium chloride $+$ Potassium sulphate $\rightarrow$ Barium sulphate $+$ Potassium chloride
solution:
(a) $\mathrm{Ca}(\mathrm{OH})_{2}+\mathrm{CO}_{2} \rightarrow \mathrm{CaCO}_{3}+\mathrm{H}_{2} \mathrm{O}$
(b) $\mathrm{Zn}+2 \mathrm{AgNO}_{3} \rightarrow \mathrm{Zn}\left(\mathrm{NO}_{3}\right)_{2}+2 \mathrm{Ag}$
(c) $2 \mathrm{Al}+3 \mathrm{CuCl}_{2} \rightarrow 2 \mathrm{AlCl}_{3}+3 \mathrm{Cu}$
(d) $\mathrm{BaCl},+\mathrm{K}, \mathrm{SO}_{4} \rightarrow \mathrm{BaSO}_{4}+2 \mathrm{KCl}$
