Why does this picture demonstrate the Law of Conservation of Mass?
the number of atoms of each element are the same on both sides
they start out separate and end up combined
the same elements are used
it doesn't demonstrate the Law of Conservation of Mass
The fact that every sample of a particular chemical compound contains the same elements in exactly the same proportions by mass is known as the law of
conservation of energy.
conservation of mass.
atomic theory.
definite proportions.
If two or more compounds are composed of the same two elements, then the ratio of the masses of the second element that is combined with a certain mass of the first element is always a ratio of small whole numbers. This statement is called the law of
definite proportions.
conservation of mass.
atomic theory.
multiple proportions.
