Question

Two liters of ammonia (NH3) are made to react with 2 liters of oxygen (O2) to produce nitrous oxide (N2O) - known as laughing gas - and water vapor. How many liters of nitrous oxide and water vapor are produced?

a. one liter of nitrous oxide and one liter of water vapor.
b. one liter of nitrous oxide and two liters of water vapor.
c. one liter of nitrous oxide and three liters of water vapor.
d. two liters of nitrous oxide and one liter of water vapor.
e. three liters of nitrous oxide and one liter of water vapor.

Explanation / Answer

The reaction taking place is:

NH3 + O2 —> N2O + H2O

After balancing, it becomes:

2 NH3 + 2 O2 —> N2O + 3 H2O

from reaction above,

2 L of NH3 and 2 L of O2 reacts to form 1 L of N2O and 3 L of H2O

Answer: c
