Balance the equation: S + HNO3 H2SO4 + NO2 + H2O

Balanced equation: S + 6HNO3 H2SO4 + 6NO2 + 2H2O

Step 1: Write the unbalanced equation


S + HNO3 H2SO4 + NO2 + H2O


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



Step 3: Now, first let us consider nitrogen atom. If we multiply 6 in the reactant (HNO3) and product (in NO2), we will get the equal number of atoms.



Step 4: Write the resulting equation:


S + 6HNO3 H2SO4 + 6NO2 + H2O


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



We find that the equation is not balanced yet. As the number of hydrogen and oxygen atoms are unequal on the two sides.


first balance the oxygen atom.


Step 6: If we multiply 2 in the product (in H2O) and 6, we will get the equal number of oxygen atoms on both sides.



Step 7: Write the resulting equation:


S + 6HNO3 H2SO4 + 6NO2 + 2H2O


Step 8: Now check whether the equation is balanced or not by comparing the atoms.



Step 9: Write the resulting equation:


S + 6HNO3 H2SO4 + 6NO2 + 2H2O


We find that the equation is balanced now.


Step 10: Write down the final balanced equation:


S + 6HNO3 H2SO4 + 6NO2 + 2H2O
