1
Explanation:
To get the coefficient of the diatomic oxygen, we will need to balance the chemical reaction.
Checking the chemical equation, we can see that the number of nitrogen atoms on both sides are balanced.
We have 4 nitrogen atom on the left hand side and 4 nitrogen atoms on the right hand side.
Now for the oxygen, we have 10 on the left hand side and 8 + 2 which equals 10 too on the
right hand side
This shows that the diatomic oxygen has a coefficient of 1 on the right hand side of the balanced equation since 1 * 2 gives the 2 oxygen atoms needed to complete the balanced chemical reaction
