Question

what information do the coefficients of a balanced equation give about the reactants?
a. the coefficients give the gram ratio of the reactants.
b. the coefficients tell what the molar mass of each reactant is.
c. the coefficients tell what oxidation states the atoms are in.
d. the coefficients give the molar ratio of the reactants.

Explanation:

The coefficients in a balanced chemical equation represent the relative number of moles of each reactant and product. They give the molar ratio of the reactants to each other and to the products. For example, in the reaction \(2H_2 + O_2
ightarrow2H_2O\), the coefficient 2 for \(H_2\) and 1 for \(O_2\) indicate a 2:1 molar ratio of hydrogen to oxygen. They do not directly relate to gram - ratios, molar masses, or oxidation states.

Answer:

D. The coefficients give the molar ratio of the reactants.
