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.

Which substance has non polar covalent bonds

For part 1, describe the changes in the colors of the well, if any, as you go from well 1 to well 9—that is, as you go from the well with the least copper(ii) nitrate to the well with the most copper(ii) nitrate. which wells had the most distinct precipitate? for part 2, describe the changes in the colors of the well, if any, as you go from well 1 to well 9—that is, as you go from the well with the least iron(ii) sulfate to the well with the most iron(ii) sulfate. which wells had the most distinct precipitate? for part 3, describe the changes in the colors of the well, if any, as you go from well 1 to well 9—that is, as you go from the well with the least iron(iii) nitrate to the well with the most iron(iii) nitrate. which wells had the most distinct precipitate?
