$8 H N {O}_{3} + 3 M {g}^{o} \implies 3 M g {\left(N {O}_{3}\right)}_{2} + 2 N O + 4 {H}_{2} O$

#### Explanation:

There are several ways to balance oxidation-reduction reactions. Three popular methods are
- Half-Reaction Method => Breaking the given equation into half-reactions (one, oxidation and the other reduction), balancing each separately and then adding the two together to get the working equation.
- Extracting Half Reactions from a reduction potential table (these are usually balanced as published). Reversing the oxidation reaction and adding to the reduction reaction such that both charge and mass balance.
- Oxidation Number Method => Following a strict protocol for balancing oxidation-reduction equations and simplyfying to give the working equation.

In this note, the Oxidation Number Method is presented. but the other methods are as reliable.
