Based on the Ksp calculations, the molar solubility of AgCl in 0.500 M of NH₃ is equal to 2.77 × 10⁻² M.
How to determine the molar solubility.First of al, we would write the properly balanced chemical equation for this chemical reaction:
AgCl(s) ⇆ Ag⁺(aq)+ Cl⁻(aq) Ksp = 1.8 × 10⁻¹⁰
AgCl(s) + 2NH₃(aq) ⇆ Ag(NH₃)₂⁺(aq) Kf = 1. 7 × 10⁷
Given the following data:
Ksp of AgCl = 1.8 × 10⁻¹⁰Concentration of NH₃ = 0.500Kf of ag(nh₃)₂⁺ = 1.7 × 10⁷K = Ksp × Kf
K = 1. 80 × 10⁻¹⁰ × 1.7 × 10⁷
K = 3.06 × 10⁻³
Mathematically, the Ksp for the above chemical reaction is given by:
[tex]K=\frac{ [Ag(NH_3)_2^{+}][Cl]}{[NH_3]^2}\\\\3.06 \times 10^{-3}=\frac{[x][x]}{0.50^{2 }}\\\\3.06 \times 10^{-3}=\frac{x^2}{0.25}\\\\x^2 = 7.65\times 10^{-4}\\\\x=\sqrt{7.65\times 10^{-4}}[/tex]
x = 2.77 × 10⁻² M.

If you have a solution with a [h+] of 1.58x10-6 m, what is the ph of the same solution?
pH is the potential of the hydrogen ion concentration in an aqueous solution. The pH of the solution will be 5.801.
What is pH?pH is the measurement of the acidic and the basic characteristic of the solution by the hydrogen or the hydronium concentration.
The formula for pH is given as,
[tex]\rm pH = \rm - log [H^{+}][/tex]
Here, the concentration of the hydrogen in the solution is given as [tex]1.58 \times 10^{-6}\;\rm m.[/tex]

The area of the shaded region is = (72π - 144) mm²
What is the area of a shaded region?The area of a shaded region is that enclosed part of a plane figure that is shaded.
Suppose;
A square is inscribed in a circle with a diameter of 12√2 millimeters. Everything outside of the square is shaded.Let's first find the area of the circle.
Area of circle = [tex]\mathbf{\pi r^2}[/tex]
Area of circle = [tex]\mathbf{\pi \times (\dfrac{12 \sqrt{2}}{2})^2}[/tex]
Area of circle = 72π sq mm
We know that the side of the inscribed square = [tex]\mathbf{\dfrac{12\sqrt{2}}{\sqrt{2}}}[/tex] = 12 mm
Area of the square = side(L)²
Area of the square = 12²
Area of the square = 144 sq mm
Now, the area of the shaded region can be estimated by finding the difference between the area of the square from that of the circle.

A heavy lab cart moves with kinetic energy kinit on a track and collides with a lighter lab cart that is initially at rest. the carts bounce off each other but the collision is not perfectly elastic, causing the two-cart system to lose kinetic energy klost . a student wonders if the fraction of kinetic energy lost from the two-cart system during the collision depends on the speed of the first cart before the collision and plans to perform an experiment.
The hypothesis; greater fraction of kinetic energy is lost from the system during the collision when the speed of the first cart is greater is; Correct
What is the Hypothesis of the Collision?In an Inelastic Collision, energy is not conserved . Now, the loss of energy could be in the form of friction, vibrational energy, sound, heat energy, e.tc.
Now, for example frictional energy is proportional to the velocity. The, the greater the velocity, the greater the loss of energy. This is also true about vibrational energy, sound, heat energy, e.tc.

The most accurate statement concerning any legal challenge is that pay difference is unlawful unless Midwest can establish some significant difference between Zone A and Zone B.
Which legislation guided this practice?Equal Pay Act of 1963 was the legislation that stated that both men and women must earn the same salary for similar jobs.
The legislation prohibited discimination of gender when establishing a person's salary.

The value of WACC from the given information is about 7.4%.
What is WACC?WACC is defined as the weighted average cost of capital. It is the rate at which a firm is projected to pay all of its security holders on average to finance its assets.
The firm's cost of capital is frequently referred to as the WACC. It is important to note that the external market, not management, determines this.
The formula of WACC is:
[tex]\text{Weighted Average Cost of Capital (WACC)} = \dfrac{\text{Annual Dividend}}{\text{Sales price of Proffered Stock} - \text{Sales price} \times \text{FC}}[/tex]
According to the given information,
Annual Dividend = $8.50,
Sales price of Proffered Stock =$120.
Flotation Cost(FC) = 4%.
Now, putting the values in the formula of WACC,
[tex]\text{Weighted Average Cost of Capital (WACC)} = \dfrac{\text{Annual Dividend}}{\text{Sales price of Proffered Stock} - \text{Sales price} \times \text{FC}}\\\\\text{Weighted Average Cost of Capital (WACC)} =\dfrac{8.5}{\$120- (\$120 \times 4\%)}\\\\\text{Weighted Average Cost of Capital (WACC)} =0.074(Approx.)[/tex]
