Question

Chemical equations must be balanced to satisfy ___.
the law of definite proportions
the law of multiple proportions
the law of conservation of mass
Avogadro's principle

Answer 1

I'm pretty sure it's the law of conservation of mass

Answer 2

Answer:

Chemical equations must be balanced to satisfy the law of conservation of mass.

Step-by-step explanation:

Law of conservation of mass states that we can neither create the matter nor we can destroy it. We can just  transform it by using physical and chemical reactions.

In a chemical equation , the number of atoms of each element must be equal on each side that is the number of atoms on reactant and product side must be equal.

Mass of reactant = Mass of products.

Thus, Chemical equations must be balanced to satisfy the law of conservation of mass.
