D.The products will have at least 2 Na atoms and 1 O atom.
Further explanation
Conservation of mass states that
In a closed system, the masses before and after the reaction are the same
So it can be concluded
- mass of the reactants = mass of the products
- mass cannot be created or destroyed
- The number of atoms involved in a reaction remains the same⇒ number of moles also the same
- chemical equation in balanced form
So the number of atoms in reactants and products remains the same
Because one of the reactants in a reaction is Na₂O, so The products will have at least 2 Na atoms and 1 O atom.
