Which statement is true regarding a chemical reaction?(1 point) Responses 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. 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. 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 does not change, so mass is conserved in the reaction.

The correct statement regarding a chemical reaction is: The total number of atoms does not change, so mass is conserved in the reaction.
This is based on the law of conservation of mass, which states that in a closed system, mass is conserved in a chemical reaction, meaning that the total mass of the reactants equals the total mass of the products. Since atoms are neither created nor destroyed in a chemical reaction, the total number of atoms remains constant.
