Question

Coal can be converted to methane gas by a process called coal gasification. The equation for the reaction is the following: 2 C (s) 2 H2O (l) --> CH4 (g) CO2 (g) What mass in grams of carbon is required to react with water to form 1.00 mol CH4

Answer 1

24 g of C are needed to produce 1mol of CH₄

Step-by-step explanation:

The reaction is:

2C (s) + 2H2O (l) → CH4(g) + CO2 (g)

2 moles of carbon react with 2 moles of water in order to produce 1 mol of methane and 1 mol of carbon dioxide.

If we want to produce 1 mol of methane, we need 2 moles of C

Let's find out the mass → 2 mol . 12 g/1 mol = 24g
