3. When 20.5-g of methane and 45.0-g of chlorine gas undergo a reaction that has 75.0% yield, what mass (g) of chloromethane (CH,CI) forms? Hydrogen chioride is also formed based on the reaction: CH, + C, > CH,CI + HCI 4. Two successive reactions, A ==> B and B ===> C, have yields 93% and 68%, respectively. What is the overall percent yield for the conversion of A to C?
