Given the equilibrium constants for the following reactions: 4Cu(s) + O2(g) <--> 2Cu2O(s), K1 2CuO(s) <--> Cu2O(s) + 1/2 O2(g), K2 what is K for the system 2Cu(s) + O2(g) <--> 2CuO(s) equivalent to?

Explanation:

                      assuming equation (1)

                     assuming equation (2)

upon reverting equation (1) and multiplying equation (2) by 2

                     , assuming equation (3)

                  assuming equation (4)

upon adding equation (3) and (4) , give  equation (5)

               , equation (5)

  divide equation (5) by 2

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error

i'm wiling to try and you : )
