Consider the equilibrium reaction in the previous question. A reaction flask initially contains 0.0006 M Ni2 and 0.0002 M SCN-. After the equilibrium is reached, it is found that the concentration of Ni(SCN) is 6.0 X 10-6 M. Given the concentrations of Ni2 , SCN-, and Ni(SCN) , calculate the equilibrium concentration of Ni2 and SCN-. Determine the equilibrium constant, Kc, for the reaction. Show all work.

Explanation:

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.
