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.
True
The statement is true.
If there are same number of atoms of various elements are on either side of the equation, then total atomic mass on the products side will be equal to the reactants side. This should happen according to the law of conservation of mass in chemical reactions.
