Help with these please. It is 16 page assignment and this section I can't get right.

Equilibrium 1: Cu(OH)2(s)Cu2+(aq)+2OH(aq)K1=KspofCu(OH)2=[Cu2+][OH]2=2.21020 Equilibrium 2: 2H3O+(aq)+2OH(aq)4H2O(l) K2=[H3O+]2[OH]21 Net Equilibrium: Cu(OH)2(s)+2H3O+(aq)Cu2++2H2O(l)Knet=[H3O+]2[Cu2+] 3. Consider the autoionization of water (i.e., Equilibrium 2 ). Equilibrium 2': 2H2O(l)H3O+(aq)+OH(aq)K2=Kw=[H+][OH]=1014 Compare the laws of mass action for Equilibria 2 (in the Model) and 2'. Calculate the value of K2. 4. The summation law (i.e. Hess's Law) can also be applied to equilibria and equilibrium constants. a. Use the expressions in the laws of mass action (in the Model) as algebraic substitutions to prove that, when Equilibrium 1 is added to Equilibrium 2, the net equilibrium constant, Knet, is equal to a product of K1 and K2. Knet=K1K2 b. Calculate the value of Knet from the Model. c. Knet is larger / smaller than Ksp and therefore copper(II) hydroxide is more / less soluble in acidic solution than pure water. (Circle the underlined options that make the statement true.) 5. Compare the base strength of the anions on the product sides of Equilibrium 1 in the Model and the following chemical reaction
