Answer 2

Explanation:

☆Definition:

》Reversible reaction- reactions in which reactants which react to form products can be again converted to same initial form.That is they can change again from product to reactant.

》Irreversible reaction- reaction in which reactants cannot be get as their initial forms after forming the product.

☆Answer:

》2Mg +$\ O_{2} \rightarrow{ 2MgO}$

here magnisium oxide(MgO) is formed after Mg burned in the presence of $\ O_{2}$.

》magnesium (Mg) can't be obtain again after reaction.

》so,it is a irreversible reaction.
