Answer :

Balanced equation: Cu + 2H2SO4 CuSO4 + SO2 + 2H2O


Step 1: Write the unbalanced equation


Cu + H2SO4 CuSO4 + SO2 + H2O


Step 2: Compare the number of atoms of reactants with the number of atoms of products.



Step 3: Now, first we consider the element having unequal no. of atoms on both sides. Thus, first let us consider the oxygen atom. If we multiply 2 in the reactant (in H2SO4) and 2 in the product (in H2O), we will get the equal number of oxygen atoms in both sides.



Step 4: Write the resulting equation:


Cu + 2H2SO4 CuSO4 + SO2 + 2H2O


Step 5: Now check whether the equation is balanced or not by comparing the atoms



We find that the equation is balanced now.


Step 6: Write down the final balanced equation:


Cu + 2H2SO4 CuSO4 + SO2 + 2H2O
