Which of the following enable us characterize a compound by a specific chemical formula?
A) law of conservation of energy
B) law of conservation of mass
C) law of constant composition
D) all of the above

Question

Quizplus · Accepted Answer

The law of constant composition states that a compound is always made up of the same elements in the same proportions by mass. Therefore, knowing the chemical formula of the compound allows us to determine its elemental composition. The laws of conservation of energy and mass are important principles in chemistry, but they alone do not enable us to determine the chemical formula of a compound.
