Question

1. balance the following chemical equation and choose the correct answer below. n₂ + h₂ → nh₃ o 2n₂+3h₂ → 2nh₃ o 3n₂+3h₂ → 4nh₃ o n₂+3h₂ → 2nh₃ o 3n₂+3h₂ → 2nh₃

Explanation:

Step1: Count atoms on both sides

On the left - hand side of the unbalanced equation $N_2 + H_2
ightarrow NH_3$, we have 2 nitrogen atoms and 2 hydrogen atoms. On the right - hand side, we have 1 nitrogen atom and 3 hydrogen atoms.

Step2: Balance nitrogen atoms

To balance the nitrogen atoms, we put a coefficient of 2 in front of $NH_3$: $N_2 + H_2
ightarrow2NH_3$. Now we have 2 nitrogen atoms on both sides.

Step3: Balance hydrogen atoms

After step 2, we have 2 hydrogen atoms on the left - hand side and 6 hydrogen atoms on the right - hand side. To balance the hydrogen atoms, we put a coefficient of 3 in front of $H_2$. So the balanced equation is $N_2+3H_2
ightarrow2NH_3$.

Answer:

$N_2 + 3H_2
ightarrow2NH_3$ (the correct option among the ones shown in the image is the one with this equation)
