Hope it will work for you

Answer 2

Explanation:

Magnesium is a metal element with atomic number 12 and belonging to period 2 of periodic table. It is very reactive.  

It is burnt in oxygen or air with sparks to produce magnesium oxide and magnesium nitride.

$M g+N 2+O 2=M g O+M g 3 N 2$

MgO is the magnesium oxide and Mg3N2 is magnesium nitride.

Magnesium oxide is the basic oxide forming magnesium hydroxide or $M g(O H)^{2}$ with water. Magnesium nitride is the magnesium nitride which forms "magnesium hydroxide and ammonia" with water.
