Question

Ammonia can be prepared by the reaction of magnesium nitride with water. The prod- ucts are ammonia and magnesium hydroxide. When the equation is written and balanced, the coefficient of magnesium hydroxide is

Answer Options : 1,3,6,8

Answer 1

3

Step-by-step explanation:

This is how to write the balanced equation for the reaction of magnesium nitride with water to create ammonia and magnesium hydroxide:

1. Let's begin with the improper equation:

NH3 + Mg(OH)2 from Mg3N2 + H2O

2. Correct the coefficients to bring the equation into balance:

6H2O + 3Mg3N2 2NH3 + 3Mg (OH)2

Magnesium hydroxide (Mg(OH)2) has a coefficient of 3.
