The correct statement is: The total number of atoms does not change, so mass is conserved in the reaction.
The statement that is true regarding a chemical reaction is:
The total number of atoms does not change, so mass is conserved in the reaction.
To understand why this statement is correct, we need to consider the law of conservation of mass. According to this law, the total mass of the substances involved in a chemical reaction remains constant before and after the reaction.
During a chemical reaction, atoms are rearranged to form new compounds. However, the total number of atoms in the reactants is always equal to the total number of atoms in the products. This means that no atoms are lost or gained in the process, and therefore, the mass of the system is conserved.
To determine whether mass is conserved in a chemical reaction, you can calculate the total mass of the reactants and compare it to the total mass of the products. The masses can be obtained by using the atomic masses of the elements involved and multiplying them by the corresponding coefficients in the balanced chemical equation.
By confirming that the total mass of the reactants is equal to the total mass of the products, you can conclude that mass is conserved in the reaction.
