Based on this reaction, how many moles of H2 can be obtained starting with 3 mol CH4?

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

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
