Consider the following reaction.
Cu(NO3)2→CuO+NO2+O2
Which of the following statement is correct?
Mass of reactants is not equal to mass of products
Number of atoms on product side is more than the reactant side
In the reaction Cu(NO3)2→CuO+NO2+O2 , the no of atoms on reactant side (Cu- 1, N-2, O-6) is not equal to those on the product side (Cu- 1, N-1,O-4). So, the number of atoms on the product side are greater than reactant side.
Therefore, mass of reactants≠ mass of products.
