Question

what is a simple (\in short\) way to summarize the law of conservation of matter?
○ an object in motion will stay in motion until an outside force acts upon it
○ a chemical compound will always contain the same elements combined in the same fixed proportion by mass, regardless of where the sample came from or how it was prepared
○ matter is neither created nor destroyed, only transformed
○ energy equals mass times the speed of light squared

Explanation:

The law of conservation of matter states that in a chemical reaction, matter is not created or destroyed, only its form changes. The first option is Newton's first - law of motion, the second is the law of definite proportions, and the fourth is Einstein's mass - energy equivalence formula.

Answer:

matter is neither created nor destroyed, only transformed
