Solution

The correct option is B

False


The given chemical equation is Mg+O2MgO. We have to find if the chemical equation is balanced or not.

In a balanced chemical equation, the number of atoms of the same kind on the side of the reactants and that of the products is equal.

The number of Mg atoms in reactants is one and that in products is one.

The number of O atoms in reactants is two and that in products is one.

Hence, the chemical equation given above is not balanced.

2Mg+O22MgO

Now, if you observe, Mg and O atoms both are balanced on each side i.e. two atoms of Mg and two atoms of O on both the reactant side and product side.
