Answer:
9 moles of H₂ are produced
Explanation:
Note: The question is incomplete. the complete question and the given image is found below:
The diagram represents a high-temperature reaction between CH4 and H2O. Based on this reaction, how many moles of H2 can be obtained starting with 3 mol CH4?
From the attachment, the equation of the reaction can be written as:
2CH₄ + 2H₂O ----> 2CO + 6H₂
From the equation the reaction shown above, 2 moles of methane, CH₄ reacts with 2 moles of gaseous water or steam, H₂O (since the reaction occurs at a high temperature) to produce six moles of hydrogen gas, H₂.
Therefore, starting with 3 moles of CH₄ and assuming the number of H₂O are equal to or greater than three moles (since the mole ratio of CH₄ to H₂O is 1 : 1 according to the equation of the reaction), number of moles of H₂ that will be produced = 3 * 6/2 moles of H₂
number of moles of H₂ produced = 9 moles
Therefore, 9 moles of H₂ are produced
