Keq=7.6*10^-4 M CoCl2 is introduced in a closed container until its concentration is .890 M. What will be the concentration of Cl2 once the reaction has reached equilibrium?

You want to be careful with the caps key. CoCl2 is cobaltous chloride. COCl2 is phosgene, a huge difference.
.........COCl2 ==> CO + Cl2
I........0.890......0.....0
C........-x.........x.....x
E.......0.890-x.....x.....x

Kc = (CO)(Cl2)/(COCl2)
Substitute the E line and solve for x = (Cl2) = (CO)
