Question

which statement is true regarding a chemical reaction? (1 point) the total number of atoms does not change, so mass is conserved in the reaction. the total number of atoms changes, so mass is conserved in the reaction. even if the total number of atoms does not change, mass may not be conserved in the reaction. even if the total number of atoms changes, mass may not be conserved in the reaction.

Explanation:

In a chemical reaction, according to the law of conservation of mass, the total mass of the reactants equals the total mass of the products. This is because the total number of atoms of each element does not change during a chemical reaction. Atoms are just rearranged.

Answer:

The total number of atoms does not change, so mass is conserved in the reaction.
