What is the molar solubility of agcl (ksp = 1.80 × 10⁻¹⁰) in 0.500 m nh₃? (kf of ag(nh₃)₂⁺ is 1.7 × 10⁷)
Snowcat [4.5K]

Based on the Ksp calculations, the molar solubility of AgCl in 0.500 M of NH₃ is equal to 2.77 × 10⁻² M.

<h3>How to determine the molar solubility.</h3>

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

<u>Given the following data:</u>

  • Ksp of AgCl = 1.8 × 10⁻¹⁰
  • Concentration of NH₃ = 0.500
  • Kf of ag(nh₃)₂⁺ = 1.7 × 10⁷

K = 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:

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}}

x = 2.77 × 10⁻² M.

What value of k will make the system y-5x=-1 and y=kx +3 inconsistent?
umka21 [38]

Answer:

Inconsistent parallel lines is easiest pick k so the slopes (k) is the same as the first line.

It would be helpful to rewrite y-5x=-1 in y=mx+b where m is slope and b is y-intercept

y=5x-1  and y=kx+3  choose k=5 and you will get parallel lines and since the y intercepts are different they will be different parallel lines and inconsistent.

Now  consistent intersecting lines are easy now you know the parallel solution is inconsistent so you can choose k to be what ever you want as long as it isn't 5, to make perpendicular just use -1/5.

The center of gravity does not contribute to individual stability.
AlekseyPX

Answer:

The answer is false because the center of gravity contributes greatly to the individual stability of a person or thing. The center of gravity is the center of mass of an object and therefore by raising or lowering that point, of gravity, you can cause an object or person to lose stability very quickly.
