The exothermic dissolution of mg(oh)2(s) in water is represented by the equation below. the ksp of mg(oh)2 is 1.8 x 10-11. which of the following changes will increase the solubility of mg(oh)2 in an aqueous solution?

mg(oh)2(s) > ; mg2+(aq) + 2 oh-(aq)

adding nh3 to the solution
increasing the ph
decreasing the ph
adding mg(no3)2 to the solution

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
