Methane (CH4 MW=16.04 g/mol) and hydrogen sulfide (H2S MW=34.08 g/mol) to produce carbon disulfide and hydrogen gas indicated by this balanced reaction:CH4(g) + 2H2S(g) → CS2(g) + 4H2(g)A 32.0 g quantity of methane is reacted, but only 70.0 g of carbon disulfide is collected. What was the percent yield?
