Question

If 708 L of NO2 gas react with water, what volume of NO gas will be produced? Assume the gases are measured under the same conditions before and after the reaction. Option 1: 354 L Option 2: 212 L Option 3: 1416 L Option 4: 708 L

Answer 1

The volume of NO gas produced when 708 L of NO2 gas reacts with water is 236 L.

Step-by-step explanation:

In this question, we will use the principle of stoichiometry to determine the volume of NO gas produced when 708 L of NO2 gas reacts with water. The balanced chemical equation for this reaction is:

3 NO2 + H2O → 2 HNO3 + NO

From the balanced equation, we can see that for every 3 L of NO2, 1 L of NO is produced.

Therefore, if we have 708 L of NO2, we can divide it by 3 to find the volume of NO gas produced, which is

Option 2: 236 L
