Decomposition reactions involve the breaking down of compounds to form smaller molecules or elements.
Thus, magnesium nitride will decompose to form elemental magnesium and nitrogen gas
Mg₃N₂ → Mg + N₂
The reaction now needs to be balanced, such that the number of Mg and N atoms in the reactants is equal to that of the products.
Balanced reaction:
Mg₃N₂ → 3Mg + N₂
Ans (D)
The product that are formed during the decomposition of magnesium nitride is 3Mg + N2 ( answer D)
Explanation
magnesium nitride decompose to form magnesium and nitrogen according to equation below.
Mg3N2 → 3Mg +N2
According to reaction above 1 mole of Mg3N2 decomposes to form 3 moles of Mg and 1 moles of N2
