Write the balanced chemical equation for each of the following. (Use the lowest possible coefficients. Include states-of-matter at 1 atm and 25unknown_prefixC in your answer.)

Question

(a) the dissociation of solid magnesium hydroxide in water

Answer 1

Mg(OH)2(s) ==> Mg^2+(aq) + 2OH^-(aq)
I don't know how your prof wants to show the water. Usually it is shown as H2O and placed OVER the arrow but sometimes as H2O as if it were a reactant. The only problem doing it that way is the equation then isn't balanced.
