Solution

Balanced chemical equation -
A chemical equation is said to be balanced if the number of atoms of each element on the left-hand side is equal to the number of atoms present on the right-hand side.
In order to balance a chemical equation, it is required to know what are reactants that are taking part in a chemical reaction and what are products will be formed.
10 balanced chemical equations showing the physical states of reactants and products are as follows -
$C (s) + O_{2} (g) \to {CO}_{2} (g)$
$N_{2} (g) + O_{2} (g) \to 2 NO (g)$
$2 NO (g) + O_{2} (g) \to 2 {NO}_{2} (g)$
$S (s) + O_{2} (g) \to {CO}_{2} (g)$
${CaCO}_{3} (s) \to CaO (s) + {CO}_{2} (g)$
$2 {Ag}_{2} {CO}_{3} (s) \to 4 Ag (s) + {CO}_{2} (g) + O_{2} (g)$
$KOH (aq .) + HCl (aq .) \to KCl (aq .) + H_{2} O (l)$
${AgNO}_{3} (aq .) + HCl (aq .) \to AgCl (s) + {HNO}_{3} (aq .)$
$Mg {(OH)}_{2} (aq .) + HCl (aq .) \to {MgCl}_{2} (s) + H_{2} O (l)$
$N_{2} (g) + 3 H_{2} (g) \to 2 {NH}_{3} (g)$
