How does a balanced chemical equation satisfy the Law of Conservation of Mass?

A. During a chemical reaction, the total amount of
matter stays the same.
B. During a chemical reaction, matter is destroyed.
C. During a chemical reaction, one or more new
substances are formed.
D. During a chemical reaction, the total number of
atoms increases.

A - the law of conservation of matter states that matter can be neither be created or destroyed and it must start and end with the same amount
Given this, this eliminates B, and D.
And if we reread the question C doesn’t apply to what it’s asking, as it’s specifically asking about the Law of Conservation of Mass (even though yes this statement may be true in most circumstances when in comes to chemical reactions) Hope this helps.

If you get a map and put the countries a states all together it forms all one piece you can also tell because of the earth quakes
