The solubility of two slightly soluble salts of M^2+ , MA and MZ_2, are the same, 4 x 10^â4 mol/L.
LekaFEV [45]

Answer:

a) MZ₂

b) They have the same concentration

c) 4x10⁻⁴ mol/L

Explanation:

a) The solubility (S) is the concentration of the salt that will be dissociated and form the ions in the solution, the solubility product constant (Kps) is the multiplication of the concentration of the ions elevated at their coefficients. The concentration of the ions depends on the stoichiometry and will be equivalent to S.

The salts solubilization reactions and their Kps values are:

MA(s) ⇄ M⁺²(aq) + A⁻²(aq) Kps = S*S = S²

MZ₂(aq) ⇄ M⁺²(aq) + 2Z⁻(aq) Kps = S*S² = S³

Thus, the Kps of MZ₂ has a larger value.

b) A saturated solution is a solution that has the maximum amount of salt dissolved, so, the concentration dissolved is solubility. As we can notice from the reactions, the concentration of M⁺² is the same for both salts.

c) The equilibrium will be not modified because the salts have the same solubility. So, let's suppose that the volume of each one is 1 L, so the number of moles of the cation in each one is 4x10⁻⁴ mol. The total number of moles is 8x10⁻⁴ mol, and the concentration is:

8x10⁻⁴ mol/2 L = 4x10⁻⁴ mol/L.

The active planning stage of change is ____________. Group of answer choices maintenance action contemplation preparation
AfilCa [17]

Answer:

-Determination -  in this stage, people have make commitment to change the bad habit as soon as possible. it is stage of planning.

Explanation:

There are six stages of change that have a unique role in changing one's behavior. The stages are:

-Pre-contemplation - in this stage people are more aware of this bad habit but at the same time they are not considering as a problem

- contemplation - At this stage, people are more serious about their bad habit and now are thinking of changing

-Determination -  in this stage, people have made a commitment to change the bad habit as soon as possible. it is stage of planning.

- Action - at this stage of change people are taking a serious step toward changing their behavior

- Maintenance -  in this stage people are avoiding all those criteria and source through which there is a chance to return back to bad habits

-Relapse -  at this stage people do resumption of old behavior
