Answer #1

C(graphite) + H2O(g) ---> H2(g) + CO(g)

K = nCO*nH2/nH2O

    = 0.12*0.12/0.37

   K = 0.039

0.039 = (0.12+x)*x/(0.37+0.12-x)

x = no of mol of CO when equilibrium returns = 0.080 mol

    Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
