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)
Based on the calculations, the molar solubility of AgCl in 0. 500 M of NH₃ is equal to 2.77 × 10⁻² M.
Given the following data:
Ksp of mg(oh)₂ = 1.8 × 10⁻¹⁰Concentration of NH₃ = 0.500Kf of ag(nh₃)₂⁺ = 1.7 × 10⁷How to determine the molar solubility.First of al, we would write the properly balanced chemical equation for this chemical reaction:
[tex]AgCl(s)\rightleftharpoons Ag^{+} (aq)+ Cl^{-}(aq)[/tex] Ksp = 1.8 × 10⁻¹⁰
[tex]AgCl(s) + 2NH_3(aq)\rightleftharpoons Ag(NH_3)_2^{+}(aq)[/tex] Kf = 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:
[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.

Review of peter Sykes please.
Answer:
PETER SYKES is good book which you can definitely refer but you can not entirely rely on this book for your theory as theory in this book containing JEE syllabus is so brief that is hard to understand at once. I personally referred this book rather than SOLOMONS, because I was already in comfort with the organic chemistry and my class notes was enough for me. But our teacher asked us to read this book in general to get better insight on the topics. But if you are not comfortable at the basics itself than this book is not for you definitely, you can use another books like paula yurkaniis bruce, solomons etc. And for questions both MS chouhan and Akshay choudhary is good.

An experiment was carried out to compare electrical resistivity for six different low-permeability concrete bridge deck mixtures. there were 26 measurements on concrete cylinders for each mixture; these were obtained 28 days after casting. the entries in the accompanying anova table are based on information in an article. fill in the remaining entries. (round your answer for f to two decimal places.)
Assuming there were 26 measurements on concrete cylinders for each mixture. Alternative Hypothesis at α=0.01 will be rejected.
HypothesisElectrical resistivity(I)=6
Concrete cylinder measurement(J)=26
First step
Degree of freedom for SSb=I-1=(6-1)=5
Degree of freedom for SSw=I(1-J)=6(1-26)=150
Degree of freedom for SSr=IJ-1=(6×26)-1=155
Second step
Mean square(MSw)=13.929
SSw=MSw×I(J-1)
SSw=13.929×150
SSw=2,089.35
Third step
SSb=SSt-SSw
SSb=5,664.415-2,089.35
SSb=3,575.065
Fourth step
MSb=SSb(I-1)
MSb=3,575.065/(1-6)
MSb=3,575.065/5
MSb=715.013
Fifth step

The sets A and sets B contains items called elements
It is true that the set A is equal to set B
How to determine the true statement?
The sets are given as:
Set A and set B
Since the sets have the same power set, then we have:
P(A) = P(B)
The above means that:
For every element X in A, then the element is also in B
And
For every element Y not in A, then the element is also not in B
So, we can conclude that:
All subsets of the set A are subsets of the set B and vice versa
Hence, the set A is equal to set B

Find a parametric equation of the line m through p and q
The parametric equation of the line illustrates the independent variables x, y and z
The parametric equation of the line and direction is x = 5 + t; y = -1; z = 3 -2t
How to determine the parametric equation?The question is incomplete, as the points and the lines are not given.
So, I will make use of the following assumed parameters:
The line passes through: (5, -1, 3)The direction is ~v = <1, 0, -2>The parametric equation of the line is represented as:
r<x,y,z> = Line + t<direction>
This gives
r<x,y,z> = (5, -1, 3) + t<1, 0, -2>
Express the equation in terms of x, y and z
x = 5 + t * 1
y = -1 + 0 * t
z = 3 -2 * t
Solve the equations
x = 5 + t
y = -1
z = 3 -2t
Hence, the parametric equation of the assumed line and direction is x = 5 + t; y = -1; z = 3 -2t
