Which of the following is not conserved in a chemical reaction?
A) number of grams
B) number of atoms
C) number of molecules
D) actually, all three of these are conserved

Mass is not conserved in chemical reactions. Mass is therefore never conserved because a little of it turns into energy in every reaction

A chemical reaction is a product formation through the reactants. In a reaction the number of atoms, molecules, and mass are conserved. Thus, option D is correct.

What is a chemical reaction?

A chemical reaction involves a reactant on the left side of the reaction equation that changes to produce reactants. In a reaction, the conservational law of mass is always followed.

The number of atoms and the molecules involved in a reaction is also the same in the reactants and the products formed as can be seen from the stoichiometry coefficient of the balanced equation.

Therefore, option D. mass, atoms, and molecules are conserved in a reaction.
