Question

What is the dissociation equation for magnesium nitride

Answer 1

the dissociation equation for magnesium nitride

Thermal decomposition of magnesium nitride gives magnesium and nitrogen gas (at 700-1500 °C).

Mg₃N₂ $\mapsto$ 3 Mg_(s) + N_2(g)

Magnesium nitride reacts with water to produce magnesium hydroxide and ammoniagas

Mg₃N_2(s) + 6 H₂O_(l) → 3 Mg(OH)_2(aq) + 2 NH_3(g)
