Question

Balance the following equation:
e) $P b O + N H_{3} \to P b + H_{2} O + N_{2}$

Open in App

Solution

The skeletal equation is:
$P b O + N H_{3} \to P b + H_{2} O + N_{2}$

To equalise nitrogen, multiply NH3 by 2.

$P b O + 2 N H_{3} \to P b + H_{2} O + N_{2}$

To equalise hydrogen, multiply H2O by 3.

$P b O + 2 N H_{3} \to P b + 3 H_{2} O + N_{2}$

To equalise oxygen, multiply PbO by 3, Pb by 3

$3 P b O + 2 N H_{3} \to 3 P b + 3 H_{2} O + N_{2}$
The equation is balanced.
