question 21 of 25
what does stoichiometry use to relate moles of one molecule to moles of another?
a. coefficient ratios
b. atomic number ratios
c. oxidation state ratios
d. subscript ratios

Explanation:

Stoichiometry uses the coefficients in a balanced chemical equation. These coefficients represent the mole - to - mole ratios of reactants and products. For example, in the reaction $2H_2 + O_2
ightarrow2H_2O$, the ratio of $H_2$ to $O_2$ is 2:1 based on the coefficients.

Answer:

A. Coefficient ratios
