The following equation can be written as a balanced half-reaction for the conversion of aqueous nitrous acid HnO2 to gaseous nitric oxide in basic aqueous solution:
HNO2 (aq) ------> NO (g)
The balanced reaction is implied by the "charge balance and atom count balance" on both sides. The electrons have significance in "balancing the negative charges." The hydrogens and coefficients play a vital role in "balancing hydrogen" and other atoms, respectively.
