Question

Name the reactants and products in the following skeletal equation and balance them.
(ii) $N_2+H_2\to N{H}_3$

Answer 1

The skeletal equation is: $N_2+H_2\to N{H}_3$
Reactants are nitrogen and hydrogen, the product is ammonia

• Count the number of atoms of each element.
• To equalize $N$, multiply ${NH}_3$ by $2$

$N_2+H_2\to 2N{H}_3$

• To equalize $H$, multiply $H_2$ by $3$.

$N_2+3H_2\to 2N{H}_3$
Hence, the equation is balanced.
