Given: Mg3N2 + 3 K2O → 3 MgO + 2 K3N

How many moles of magnesium nitride, Mg3N2 is needed to react to produce 11.6 grams of MgO? Show work

Sagot :

Answer:

0.11

Explanation:

This equation is not balanced because there is an unequal amount of O's on both sides of the equation. The left hand side has 4 P's and the right hand side has 4 P's. So the P atoms are balanced. The left hand side has 2 O's and the right hand side has 10 O's.

To fix this unbalanced equation a 5 in front of the O2 on the left hand side is added to make 10 O's on both sides resulting in

P4 + 5O2 = 2P2O5

The equation is now balanced because there is an equal amount of substances on the left and the right hand side of the equation.
