For the reaction c + 2h2 → ch4, how many moles of hydrogen are required to produce 10 moles of methane, ch4?

                                                 C+2H2 > CH4   
from reaction                              2 mol           1 mol
from the problem                       x mol           10 mol

x=2*10/1 = 20 mol

20 mol of H2.

Answer(true);
