How many moles of methane are produced when 36.6moles moles of carbon dioxide gas react with excess hydrogen gas?

Question

How many moles of methane are produced when 36.6moles  of carbon dioxide gas react with excess hydrogen gas?

Answer 1

the balanced chemical equation for this reaction is

CO2​(g) + 4H2​(g) → CH4​(g) + 2H2​O(l)

meaning that the ratio of CO2 to CH4 is 1:1 and the amount of methane produced is directly proportional to the amount of carbon dioxide consumed

36.6 mol CO2 x 1 mol CH4 / 1 mol CO2 = 36.6 mol CH4

i hope that helps get you moving in a good direction on that one! feel free to reach out if you have any additional questions beyond that :)

Answer 2

Lakeenya,

 

Remember the chemical equation from the previous problem: CO₂ + 4 H₂ → CH₄ + 2 H₂O

 

If hydrogen gas is in excess, the number of moles of carbon dioxide will determine how many moles of methane will be formed.  For each mole of carbon dioxide, you will produce one mole of methane.  Therefore, for 36.6  moles of carbon dioxide, you will produce 36.6 moles of methane.

 

Hope it helps.
