In a gas stoichiometry experiment, a graph shows the volume of O_2 (in liters) on the left y-axis and the volume of CO_2 (in liters) on the right y-axis as a function of time. Which gas is plotted using the y-axis on the right?

• A. H_2
• B. CO_2
• C. O_2
• D. N_2

Answer: (B)

Verified step by step guidance

1. Identify the gases involved in the experiment and the variables plotted on the graph. The problem states that the volume of O_2 is on the left y-axis and the volume of CO_2 is on the right y-axis.
2. Understand that each y-axis corresponds to a different gas volume, so the gas plotted on the right y-axis is the one explicitly mentioned as being on the right side.
3. Since the problem states the volume of CO_2 is on the right y-axis, this means CO_2 is the gas plotted using the right y-axis.
4. Confirm that the other gases listed (H_2 and N_2) are not mentioned as being plotted on either y-axis, so they are not relevant to the axes in question.
5. Conclude that the gas plotted on the right y-axis is CO_2, based on the information given in the problem.
