H2SO4 + 2NaOH → Na2SO4 + 2H2O
- The equation for the reaction is balanced by using coefficients; 1,2,1,2
- According to the law of conservation of mass the mass of the reactants should be equal to the mass of the products.
- For the law of conservation of mass to be obeyed, chemical equations must always be balanced.
