Ethanol (C2H6O), the intoxicant in alcoholic beverages, is also used as a precursor of many other organic compounds. In acid solution, ethanol forms diethyl ether (C4H10O): 2 C2H6O --> C4H10O + H2O If 50.0 g of ethanol yields 33.9 g of diethyl ether, what is the percent yield for the reaction?
Cl2(g) + F2(g) 2 ClF(g) Kc = 19.9 For the reaction forming ClF the initial concentrations are as follows: [Cl2] = 0.5 M ; [F2] = 0.2 M ; [ClF] = 7.3 M Is the reaction at equilibrium? If not, in which direction with the reaction shift to reach eq..
