What pressure is required to achieve a co2 concentration of 5.80×10−2 m at 20∘c?

Chemistry

The concentration (c) of a gas at pressure (p) at a given temperature (T) through the Henry's constant kH

c = kH * p

at 20 C or 293 K, the henry's constant kH for CO2 = 0.037 mol/L-atm

Given concentration c = 0.0580 moles/L

Hence the pressure is given as:

p = c/kH = 0.0580 molesL-1/0.037 molL-1atm-1 = 1.57 atm

Pressure required is 1.57 atm

The ksp of pbi2 is 1.4 x 10-8. what is the molar solubility of lead(ii iodide in a solution of 0.400 m sodium iodide?
tino4ka555 [31]
The solubility product of a substance us calculated by the product of the concentration of the dissociated ions in the solution raise to the stoichiometric coefficient of the ions. Therefore, we need the dissociation reaction. For this, it will have the reaction:

PbI2 = Pb^2+ + 2I-

We solve as follows:

Ksp = [Pb2+][I-]^2 = <span>1.4 x 10-8
</span><span>1.4 x 10-8 = x(2x)^2
</span><span>1.4 x 10-8 = 4x^3
x = 1.5x10^-3 M

The molar solubility would be </span>1.5x10^-3 M.

Assignment<br>Explain why it is not advisable to wear<br>black silky cloth in the sun​
Crazy boy [7]

Answer:

It is not water absorbant and also the colour black, due to it's dark nature makes the person wearing the cloth feel hot. Unlike cotton, silk is not at all water absorbant as it does not absord any sweat produced in the wearers body

Ilia_Sergeevich [38]

He could be blindfolded and know which was his and which was his sister's. All he would need to do is pick them both up and if they were too big then pick them up one at a time. The lumber might make it harder to tell, but this is a question about physical properties.

So there is a change in mass which for the purpose of this question should be  quite different. His sister's ought to be much lighter than his. He would find it easier to pick up.
