Consider this balanced equation 3H2+CO -> CH4+H2O. how many moles of CH4 can be obtained by reached 2.0mol of H2 with 2.0molCO according to this equation?
<<Consider this balanced equation
3H2 + CO -> CH4+H2O.
How many moles of CH4 can be obtained by reacting 2.0 mol of H2 with 2.0 mol CO according to this equation?>>
You need three times as many moles of H2, as CO. Since there are equal moles of H2 and CO available, you will run out of H2 after consuming 2.0 moles of it, which will consume 2/3 mole of CO and make 2/3 mole of CH4.
