Expert Answer

Step 1

1 mol of magnesium nitride reacts with 3 mol of water to give 3 mol of magnesium oxide and ammonia. A balanced reaction is shown below:

Step 2

The molar mass of magnesium nitride is 100.94 g/mol, molar mass of water is 18.00 g/mol and molar mass of magnesium oxide is  g/mol. 40.30 g/mol.

100.94 g Mg,N,→54 g of H,O 3.82 g Mg,N2 → 100.94 g = 2.04 g of H,0 54 g x3.82 g of H,O

Step 3

7.73 g of water is available so, it is in excess. Thus, magnesium nitride is the limiting reagent.

The m...

100.94 g Of Mg,N,→120.9 g of MgO 120.9 g ×3.82 g of MgO 100.94 g 3.82 g Mg,N2 = 4.575 g of MgO
