Consider the following reaction: cis-C2H2F2↔ trans-C2H2F2 Keq = 0.500. If 1 mol cis-C2H2F2 is mixed with 1 trans-C2H2F2 in a volume of 10-Liters at 623 Kelvin, what would happen to each of these isomers when the mixture is allowed to equilibrate? Note: Equilibrium mixtures of isomers typically contain more of the cis isomer than the trans isomer. What is the value of x (mol) in the table below?

Two methanol-water mixtures are contained in separate flasks. The first mixture contains 40.0 wt% methanol and the second contains 70.0 wt% methanol. The product stream contains a mixture of methanol and water. If 200 g of the first mixture is combined with 150 g of the second, what is the mass of methanol in the product stream?
