Chapter 5: Problem 25

Ammonia burns in oxygen gas to form nitric oxide (NO) and water vapor. How many volumes of NO are obtained from one volume of ammonia at the same temperature and pressure?

Short Answer

Expert verified
One volume of ammonia will produce one volume of nitric oxide. Because the volume ratio of NH3 to NO is 1:1 according to the balanced chemical equation.

Step by step solution

01

Writing the Chemical Equation

The chemical equation of the reaction of ammonia with oxygen to produce nitric oxide and water is initially written as follows: NH3 + O2 -> NO + H2O
02

Balancing the Chemical Equation

To balance the chemical equation, we must ensure that there are equal numbers of each type of atom on both sides of the equation. We can use trial and error to find the correct coefficients. The balanced equation is: 4NH3 + 5O2 -> 4NO + 6H2O. From this equation we can infer that 4 volumes of NH3 produces 4 volumes of NO.
03

Calculating the Volume Ratio of NH3 to NO

The coefficients in the balanced equation give the volume ratio of the reactants and products. Therefore, one (1) volume of ammonia (NH3) will produce one (1) volume of nitric oxide (NO). This is because the coefficients of NH3 and NO are the same in the balanced chemical equation.
