Question

Coal can be converted to methane gas by a process called coal gasification. The equation for the reaction is the following: 2C(solid) + 2H2O2(liquid) yields CH4(gas) + CO2(gas). What mass I'm grams of carbon is required to react with water to form 2 mil CH4? Coal can be converted to methane gas by a process called coal gasification. The equation for the reaction is the following: 2C(solid) + 2H2O2(liquid) yields CH4(gas) + CO2(gas). What mass I'm grams of carbon is required to react with water to form 2 mil CH4?

Explanation / Answer

For the given reaction,

2C(s) + 2H2O2(l) --> CH4(g) + CO2(g)

1 mole of CH4 is produced by reacting 2 moles of C

So,

To produce 2 mols of CH4

we would need = 2 x 2

                         = 4 mols of C

mass of C needed = 4 mol x 12 = 48 g
