<span>Answer:
CuX = Cu2+ + X2-
Ksp = [Cu2+] * [X2-]
for each mole of CuX that dissolves we get x mol of each of the anions and cations
Ksp = x^2 = 1.27 x 10 ^-36
x= 1.13 x 10 ^-18 moles of CuX per liter of pure water
if the solution has [Cu2+]= 0.27 M
Ksp becomes x ( x + 0.27)
as we can see above x is extremely small so can be ignored inside the brackets
0.27 x = 1.27 x 10^-36
x = 1.27 x 10^-36 / 0.27 = 4.70 x 10 ^-36 moles per liter
In 0.19M X2- we have
Ksp = 0.19x = 1.27 x 10^-36
x = 1.27 x 10^-36 / 0.19 = 6.68 x 10 ^-36 moles per liter</span>
Answer:
SO2 => sulphur dioxide
P2CL5 =>Diphosphorus pentachloride
N2O4 =>Dinitrogen tetroxide
THEY ARE ALL NONMETALS ARE THE CORRECTA NSWER
The relationship between the surface area of a molecule and the strength of the intermolecular forces states that the larger the surface area, the weaker the intermolecular forces; Correct answer is True.
<h3>What are intermolecular forces?</h3>
Intermolecular forces are the forces that exist between the molecules of a substance.
The intermolecular forces present in a substance depends on the nature of the substance.
Also, the surface area of a substance affects the intermolecular forces present in the substances.
The greater the surface area, the stronger the intermolecular forces.
In conclusion, intermolecular forces exists between molecules of a substance.

Answer:
(a) See below
(b) 103.935 °F; 102.235 °F
Explanation:
The equation relating the temperature to time is
1. Calculate the thermometer readings after 0.5 min and 1 min
(a) After 0.5 min
(b) After 1 min
2. Calculate the thermometer reading after 2.0 min
T₀ =106.321 °F
ΔT = 100 - 106.321 °F = -6.321 °F
t = t - 1, because the cooling starts 1 min late
3. Plot the temperature readings as a function of time.
The graphs are shown below.
