To correct the given chemical equation, we need to ensure that the number of atoms of each element is balanced on both sides of the equation.
The original equation is:
\[ 1N_2 + 4H_2 \rightarrow 2NH_3 + 1H_2 \]
On the left side, there are:
- 2 nitrogen (N) atoms (from 1N₂)
- 8 hydrogen (H) atoms (from 4H₂)
On the right side, there are:
- 2 nitrogen (N) atoms (from 2NH₃)
- 7 hydrogen (H) atoms (6 from 2NH₃ + 1 from 1H₂)
This means that the hydrogen is not balanced, as there are 8 H atoms on the left and only 7 on the right.
To balance it, we can remove 1 molecule of H₂ from the left side:
This results in the following corrected equation:
\[ 1N_2 + 3H_2 \rightarrow 2NH_3 \]
This equation now has:
- 2 nitrogen (N) atoms on both sides
- 6 hydrogen (H) atoms on both sides (3H₂ on the left gives 6 H)
Therefore, the correct response is:
Remove a H₂ molecule from the left side of the equation.
