Which statement is true regarding a chemical reaction?(1 point) Responses Even if the total number of atoms changes, mass may not be conserved in the reaction. Even if the total number of atoms changes, mass may not be conserved in the reaction. The total number of atoms changes, so mass is conserved in the reaction. The total number of atoms changes, so mass is conserved in the reaction. The total number of atoms does not change, so mass is conserved in the reaction. The total number of atoms does not change, 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 does not change, mass may not be conserved in the reaction. Skip to navigation

Answer 1

The correct statement regarding a chemical reaction is: The total number of atoms does not change, so mass is conserved in the reaction.

This reflects the law of conservation of mass, which states that in a closed system, mass is conserved during a chemical reaction. The number of atoms before and after the reaction remains the same, although they may be rearranged to form different molecules.
