Hydrogen gas is used for many purposes, including the hydrogenation of vegetable oils to make margarine. The most common industrial process for producing hydrogen is "steam reforming," in which methane gas, CH4, from natural gas reacts with water vapor to form carbon monoxide gas and hydrogen gas

How many moles of hydrogen form when 10 moles of methane react completely?

To determine the number of moles of hydrogen gas formed when 10 moles of methane react completely, we can refer to the balanced chemical equation for the reaction:

CH4 + H2O -> CO + 3H2

From the balanced equation, we can see that for every one mole of methane (CH4) that reacts, three moles of hydrogen gas (H2) are produced.

Therefore, if 10 moles of methane react, we can calculate the moles of hydrogen gas produced by multiplying the number of moles of methane by the stoichiometric ratio:

10 moles CH4 x (3 moles H2 / 1 mole CH4) = 30 moles H2

Therefore, when 10 moles of methane react completely, 30 moles of hydrogen gas will be formed.

To determine the number of moles of hydrogen gas formed when 10 moles of methane react completely, we need to use the balanced chemical equation for the reaction.

The balanced chemical equation for the steam reforming of methane can be written as:

CH4 + H2O -> CO + 3H2

From the balanced equation, we can see that for every one mole of methane, 3 moles of hydrogen gas are formed.

Therefore, if we have 10 moles of methane, we can multiply this by the mole ratio to find the number of moles of hydrogen gas formed:

10 moles CH4 x (3 moles H2 / 1 mole CH4) = 30 moles H2

Therefore, when 10 moles of methane react completely, 30 moles of hydrogen gas are formed.
