The reaction between ammonia (NH₃) and nitrous oxide (N₂O) doesn't directly form ammonia. Instead, they react to produce nitrogen gas (N₂) and water (H₂O). Here's the balanced chemical equation:

2 NH₃ + 3 N₂O → 4 N₂ + 3 H₂O

Electron Transfer:

This reaction involves a transfer of electrons, making it a redox reaction. Here's a breakdown:

* Oxidation: Nitrogen in ammonia (NH₃) is oxidized from -3 to 0 in nitrogen gas (N₂).

* Reduction: Nitrogen in nitrous oxide (N₂O) is reduced from +1 to 0 in nitrogen gas (N₂).

To calculate the number of electrons transferred:

1. Identify the changes in oxidation states:

* Nitrogen in ammonia (NH₃) changes from -3 to 0 (a change of +3).

* Nitrogen in nitrous oxide (N₂O) changes from +1 to 0 (a change of -1).

2. Balance the electron transfer:

* For each nitrogen atom in ammonia, 3 electrons are lost.

* For each nitrogen atom in nitrous oxide, 1 electron is gained.

3. Consider the stoichiometry:

* There are 2 nitrogen atoms in ammonia and 3 nitrogen atoms in nitrous oxide in the balanced equation.

Calculation:

* Ammonia: 2 nitrogen atoms * +3 electrons/atom = +6 electrons

* Nitrous oxide: 3 nitrogen atoms * -1 electron/atom = -3 electrons

Therefore, a total of 3 electrons are transferred per molecule of ammonia and nitrous oxide that react.
