$\;\large\underbrace{\underline{\sf{Balanced\;Chemical\;Equation}}}$

The atoms of an each element remains equal at both reactant and product side is called as balanced chemical equation.

$\large\sf\red{\underline{\underline{Example \: :}}}$

1. $\ \sf H_2 \ + \ O_2 \longrightarrow 2H_2O$

2. $\ \sf Zn + 2HCl \longrightarrow ZnCl_2 \ + \ H_2$
