Question

Write a balanced chemical equation with the help of chemical symbols and formulas for the following reactions:

(i) Zinc + Silver nitrate $⟶$ Zinc nitrate + Silver

(ii) Copper oxide + Hydrogen $⟶$ Copper + Water

(iii) Barium chloride + Aluminium sulphate $⟶$ Barium sulphate + Aluminium chloride

Answer 1

The balanced reactions are given below-

(i) $\underset{\left(\text{Zinc}\right)}{Zn}+\underset{\left(\text{Silver nitrate}\right)}{2AgN{O}_3}⟶\underset{\left(\text{Zinc nitrate}\right)}{Zn{\left(N{O}_3\right)}_2}+\underset{\left(\text{Silver}\right)}{2Ag}$

(ii) $\underset{\left(\text{Copper oxide}\right)}{CuO}+\underset{\left(\text{Hydrogen}\right)}{H_2}⟶\underset{\left(\text{Copper}\right)}{Cu}+\underset{\left(\text{Water}\right)}{H_{2}O}$

(iii) $\underset{\left(\text{Barium chloride}\right)}{3Ba{Cl}_2}+\underset{\left(\text{Aluminium sulphate}\right)}{{Al}_2{\left(S{O}_4\right)}_3}⟶\underset{\left(\text{Barium sulphate}\right)}{3BaS{O}_4}+\underset{\left(\text{Aluminium chloride}\right)}{2Al{Cl}_3}$
