Solution

For balancing a chemical equation, the number of atoms should be equal on both the sides (LHS and RHS). Keeping this conditions in mind, let's balance the below given equations.

(a) $Mg + H_{2} {SO}_{4} \underset{}{\to} {MgSO}_{4} + H_{2}$

(b) ${CaCO}_{3} + 2 HCl \to_{}^{} {CaCl}_{2} + H_{2} O + {CO}_{2}$

(c) $Ca + H_{2} O \underset{}{\to} Ca {(OH)}_{2}$

(d) $Ag + 2 {HNO}_{3} \underset{}{\to {AgNO}_{3} + H_{2} O + {NO}_{2}}$
