Solution

The correct option is C
Mass of reactants is not equal to mass of products

The reaction $C u (N O_{3})_{2} \to C u O + N O_{2} + O_{2}$ , the atoms on reactant side (9) is not equal to the product side (7).

Therefore, mass of reactants≠ mass of products.

Mass of reactants is equal to the mass of products. A reaction has the same number of atoms of different elements on either side of a chemical equation.

Mass of reactants is equal to mass of products if the reaction has same number of atoms of different elements on either side of the chemical equation respectively.

In a chemical reaction, the mass of the reactants is equal to the mass of the products if the reaction has the same number of atoms of different elements on either side of the chemical equation respectively.

For balancing chemical reactions, the number of the atoms on the reactant side should be equal to the number same atoms on the product side.
