Question

How many moles of methane are produced when 48.1 moles of carbon dioxide gas react with excess hydrogen gas?

Answer 1

best idea is to write the balanced equation for it

Answer 2

since it tells us that hydrogen gas is the excess reagent, then carbon dioxide is the limiting reactant

Answer 3

so that means, when a reactant is limiting, all of it is consumed in the reaction. then we simply find its molar ratio between carbon dioxide and methane to determine the moles of methane produced

Answer 4

so write a balanced equation for this reaction first
