Question

In the presence of a platinum catalyst, ammonia, NH3, burns in oxygen, O2, to give nitric oxide, NO, and water vapor. How many volumes of nitric oxide are obtained from one volume of ammonia, assuming each gas is at the same temperature and pressure?

Answer 1

According to the balanced chemical equation, when ammonia burns in oxygen with a platinum catalyst, one volume of ammonia produces one volume of nitric oxide, given that all gases are at the same temperature and pressure.

Step-by-step explanation:

When ammonia, NH3, burns in oxygen, O2, to give nitric oxide, NO, and water vapor, we can look at the balanced chemical equation to understand the volume relationships between reactants and products. From the balanced chemical reaction:

• 4NH3(g) + 5O2(g) → 4NO(g) + 6H2O(g)

This tells us that four volumes of NH3 will produce four volumes of NO under the same temperature and pressure. Therefore, one volume of ammonia will produce one volume of nitric oxide.

Answer 2

1 volume of NO

Step-by-step explanation:

First let us generate a balanced equation for the reaction between NH3 and O2 to produce NO and water. This is shown below:

4NH3 + 5O2 —> 4NO + 6H2O

From the equation,

4 volumes of NH3 produced 4 volumes of NO.

Therefore, 1 volume of NH3 will also produce 1 volume of NO
