Which products are formed during the decomposition of magnesium nitride (mg3n2)? a. mg + 3n2 b. 3mg + 2n2 c. mg + 3n d. 3mg + n2 e. 2mg + 3n

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
