Enter the the ksp expression for the solid ab2 in terms of the molar solubility x.

Answers

Answer 1

Answer:

The Ksp Expression for the given solid in molar solubility terms is; Ksp = 4x³

What is the expression of Molar Solubility?

Ksp is simply defined as solubility product constant and it is the equilibrium expression for the dissolving of a solid.

Now, the solid ab₂ dissolved as shown in the formula;

ab₂(s) → a(aq) + 2b(aq)

Thus, the equilibrium constant is;

Ksp = ([a][b]²)/[ab₂]

Now, since the solids are not put into the equation as a result of not having enough concentration, it can be simplified to;

Ksp = [a][b]².

Now, Molar solubility another term for molarity and as such it means we will say; x = a

Since b = 2x, there is twice the amount of b than a and as such we can write a and b in terms of x to get;

Ksp = [x][2x]² = 4x³

Answer 2

Answer: Ksp is the equilibrium expression for the dissolving of a solid. The solid ab2 dissolved with the formula ab2(s)-->a(aq)+2b(aq) so the equilibrium comstant is K=([a][b]^2)/[ab2] and since solids are not put into the equation due to the fact that solids don't really have a concentration, it simplifies to K=[a][b]^2. Since Ksp is is how much solute can dissolve at equilibrium Ksp=[a][b]^2. Molar solubility is just another way of saying molarity so if you make x=a you know that b=2x since there is twice the amount of b than a. With those values for a and b in terms of x you can make Ksp=[x][2x]^2 which means that Ksp=4x^3. I hope that helps. Let me know if anything is unclear.

How many images of a candle will be formed if it is placed between two plane mirrors inclined at an angle of 45?

Answers

A candle placed between two plane mirrors inclined at an angle of 45 degrees will form 7 images. This is due to multiple reflections between the mirrors. The number of images depends on the angle between the mirrors.

In physics, when a candle is placed between two plane mirrors inclined at an angle of 45 degrees, 7 images will be formed. This happens due to multiple reflections between the mirrors. As per the formula for number of images n = 360/θ - 1, where θ is the angle between the mirrors, for an angle of 45 degrees, we get n = 360/45 - 1 = 7. The actual number of images can be less than this if they overlap each other.

Ammonia, NH3, can be classified as a base because in a chemical reaction with an acid, ammonia will (1 point)produce hydroxide ions in solution. produce hydronium ions in solution. donate a proton and become NH2–. accept a proton and become NH4+.

Answers

Answer: Option (d) is the correct answer.

Explanation:

Bases are the electron rich species which readily accept a proton. Therefore, when ammonia is classified as a base in a chemical reaction with an acid, it readily accepts a proton to give ammonium cation.

For example, the reaction of ammonia with hydrochloric acid will be as follows.

$NH_(3) + HCl \rightarrow NH^(+)_(4) + Cl^(-)$

Thus, we can conclude that ammonia, $NH_(3)$ , will accept a proton and become $NH^(+)_(4)$ .

NH will accept a proton and become NH4+

Bases follow $B^-+H^+=BH$ , with $B^-=NH_3$ in our case.

Balance the following equation. Then determine the mole ratio of Ca(OH)2:Al(OH)3. Al2(SO4)3 + Ca(OH)2 Al(OH)3 + CaSO4

Answers

To balance the reaction, we look at the number of atoms of each element we have. It should be equal for both sides. The balanced reaction is:

Al2(SO4)3 + 3Ca(OH)2 = 2Al(OH)3 + 3CaSO4

The ratio of calcium hydroxide and aluminum hydroxide is 3:2.

Answer: The mole ratio of $Ca(OH)_2:Al(OH)_3$ is 3 : 2

Explanation:

Law of conservation of mass states that mass can neither be created nor be destroyed, but it can only be transformed from one form to another. In a chemical reaction, total number of individual atoms on reactant side must be equal to the total number of individual atoms on the product side.

All the balanced chemical equation follows law of conservation of mass.

The balanced chemical equation for the combination of aluminium sulfate with calcium hydroxide is:

$Al_2(SO_4)_3+3Ca(OH)_2\rightarrow 2Al(OH)_3+3CaSO_4$

Mole ratio of any two compounds is basically the ratio of their stoichiometric coefficients.

Hence, the mole ratio of $Ca(OH)_2:Al(OH)_3$ is 3 : 2
