A general equation doesn't exist; this depends on type of the chemical reaction involved.
The chemical symbol (not equation) of hydrogen is H; the diatomic molecule is H2.
"MN" is not a chemical symbol, but "Mn" in a chemical equation signifies the involvement of at least one manganese atom in the reaction for which the equation is valid.
These subscripts are down the chemical symbol and at right. Example: O2
With this symbol:
It's called chemical weathering. Think acid rain.
The chemical symbol (not equation) of lithium is Li.
