QUICK HURRY FIRST ANSWER GETS BRAINLIST Why is it important to add coefficients to the reaction equation to make it balanced? (Hint: your
answer should talk about the law of conservation of mass)

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.

Elias is almost correct. he just got it backwards.the correct answer is that it demonstrates elastic potential energy transforming into kinetic energy.
