Consider the reaction between sodium metal and chlorine gas to form sodium chloride: 2Na(s)+ Cl₂(g)→ 2NaCl(s)Which of the following is not conserved in this reaction?

Question

Quizplus · Accepted Answer

In the reaction, the total number of atoms and the total mass of the reactants and products remain conserved. However, the number of molecules changes, as two separate reactants (sodium and chlorine) combine to form one product (sodium chloride). Therefore, moles of molecules are not conserved in this reaction.
