How many moles of hydrogen gas are needed to react with excess carbon dioxide to produce 99.1 moles of water vapor?

Answer :

Final answer:

The reaction of carbon dioxide with hydrogen gas to produce water vapor operates on a 1:1 ratio. Thus, to produce 99.1 moles of water vapor, 99.1 moles of hydrogen gas would be needed.

Explanation:

To answer your question on how many moles of hydrogen gas would be needed to react with excess carbon dioxide to produce 99.1 moles of water vapor, it's crucial to understand the balanced chemical equation for this reaction. The reaction is:

CO2 + 2H2 -> CH4 + 2H2O

From the balanced equation, we can see that 2 moles of hydrogen gas (H2) react with 1 mole of carbon dioxide (CO2) to produce 2 moles of water vapor (H2O). This means the reaction ratio of hydrogen gas to water vapor is 1:1.

Therefore, to produce 99.1 moles of water vapor, you would need 99.1 moles of hydrogen gas.
