question 19
what does the law of multiple proportions account for?
coeffcients in chemical formulas
coeffcients in chemical equations
subscripts in chemical formulas
direction of the arrow in chemical equations

Explanation:

The law of multiple proportions states that when two elements combine to form more than one compound, the masses of one element that combine with a fixed mass of the other element are in the ratio of small whole numbers. This relates to the subscripts in chemical formulas (which represent the ratio of atoms of different elements in a compound). Coefficients in chemical formulas are not a thing (coefficients are in equations), coefficients in equations relate to stoichiometry (law of definite proportions/conservation of mass), and the arrow direction is about reaction direction (not related to multiple proportions). So the law of multiple proportions accounts for subscripts in chemical formulas.

Answer:

C. subscripts in chemical formulas
