Answer:
B.) The coefficients give the molar ratio of the reactants.
Explanation:
The coefficients represent how many of each molecule are within a reaction. Coefficients are added to make sure the amounts of each element are the same on both sides of the reaction. You can use the coefficients to convert between moles of each molecule. As such, the best answer is B.) because coefficients are what allow you to construct a mole ratio.
It's just H20 but with 3 water molecules
