Question

balance the equation

Explanation:

Step1: Balance nitrogen atoms

There are 2 nitrogen atoms in \(N_2\). So, put 2 in front of \(NH_3\).
\(N_2 + H_2
ightarrow 2NH_3\)

Step2: Balance hydrogen atoms

There are 6 hydrogen atoms in \(2NH_3\). So, put 3 in front of \(H_2\).
\(N_2 + 3H_2
ightarrow 2NH_3\)

Answer:

1, 3, 2
