Question

how do we balance chemical e​

Answer 1

Generally, we did it by hit and trial method but in 11 and 12 class it can also be done by oxidation number method etc.

Answer 2

Explanation:

1) write down the equation.

2) if the number of atoms on both the sides of an equation is not equal then make them equal by adjusting a coefficient in front of the symbols and formulae of the reactants and profucts.

For example :-

Mg + O2 => MgO(skeletal equation)

2Mg + O2 => 2MgO(balanced equation).
