Answer:
the sum of the coefficients in the balanced chemical equation is 9
Explanation:
The computation of the sum of the coefficients in the balanced chemical equation is shown below:
here is the balanced chemical equation
Now the sum is
= 2 + 4 + 2 + 1
= 9
hence, the sum of the coefficients in the balanced chemical equation is 9
and, the same is to be considered
