15. why are the coefficients important in a balanced chemical equation- other than the fact that they are used to balance the equation? what else are they used for? (3 points total) *

The coefficients in a balanced chemical equation are important because they give the ratio of the reactants and the products.

Those ratios are fixed and when the reagents react do it in the same proportion and yield the products  in the same proportion of the coefficients.

Then, the coefficients are the basis for the calculations of  the amount of substances that react and the amount of substances that are formed as result of the reaction.

Ithink the answer is pollution in the air steel made of iron and carbon
