Question 12 (2 points) What is the equilibrium constant for the chemical equation:
+ 2P-3
Mg3P2 (s) + 3Mg+2
(aq) (aq)
At equilibrium, the concentration of Mg3P2 is 5.5 x 10-6 M, the concentration of magnesium ions is 7.2 x 107
5M, and the concentration of phosphide ions is 9.8 x 10-8 M.
Write out the equilibrium constant, Keq and show you work.

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins. co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
