How to balance H2SO4 + Na2O?
To balance the chemical equation H2SO4 + Na2O → Na2SO4 + H2O, we need to ensure that the number of atoms of each element is the same on both sides of the equation.
To balance the equation, we can start by balancing the sulfur (S) atoms. Since there is only one sulfur atom on each side, it is already balanced.
