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

what is the general relationship between a galaxy's distance from earth and its speed?

the answer is:

the farther away a galaxy is from us, the faster it is moving away from us.

i think it's c. i'm not sure but i think so.

im pretty sure its b

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
