Using a value of Ksp = 1.8 x 10-2 for the reaction PbCl2(s) Pb+2(aq) + 2Cl-(aq). The concentration of the products yields a value of 2.1 x 10-2.

Select the TWO statements that are true.

Ions are recombining to form a solid precipitate.
The concentrations of Pb+2(aq) and Cl-(aq) are expected to decrease.
The concentrations of Pb+2(aq) and Cl-(aq) are expected to increase.
The concentration of PbCl2(s) is expected to increase.
It is not possible to have a system with Ksp > 1.8 x 10-2.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

so she was walking and she stepped on warm jeffy , uh uh uhh dadye i just pooped my pants
