In which way does a balanced chemical equation demonstrate the conservation of matter? O A. It shows the same number of atoms of each element on both sides of the equation.
B. It shows how the atoms of an element can appear on only one side of the equation.
C. It shows how matter can be both created and destroyed by a chemical reaction.
D. It shows the same number of molecules of each compound on both sides of the equation.

A. It shows the same number of atoms of each element on both sides of the equation.

Explanation:

A balanced chemical equation demonstrates the conservation of matter by showing the number of atoms of each element on both sides of the equation or expression.

According to the law of conservation of matter, matter is neither created nor destroyed in the course of a chemical reaction but atoms are rearranged.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
