Question

How does the law of conservation of matter apply to chemical equations?A.The sum of the coefficients on each side of the equation must be the same.B.The sum of the atomic masses on both sides of the equation must be the same.C.The sum of the atomic numbers on both sides of the equation must be the same.D.The total number of atoms of each element on both sides of the equation must be the same.

Answer 1

The Law of Conservation of Mass basically states that no matter can be created or destroyed. In chemistry, this has to do with balancing chemical equations so that one side doesn't have more of an element than the other side does.

The answer in this case would be D, because it has to do with the total number if atoms of each element.

Answer 2

Answer: The total number of atoms of each element on both sides of the equation must be the same for every chemical equation.

Step-by-step explanation:

Law of conservation of matter states that matter can neither be created nor be destroyed but it can only be transformed from one form to another form.

This also means that total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side.

Every balanced chemical equation follows law of conservation of matter.

For Example: Formation of water molecule from hydrogen and oxygen gas. The equation follows:

`2H_2+O_2\rightarrow 2H_2O`

On reactant side:

Number of hydrogen atoms = 4

Number of oxygen atoms = 2

On product side:

Number of hydrogen atoms = 4

Number of oxygen atoms = 2

Hence, the total number of atoms of each element on both sides of the equation must be the same for every chemical equation.
