Calculate the partial pressure of helium gas for a volume of 1.0 x 10^-6 m^3 of 212rn gas after 91 minutes. the radon gas was originally placed in an evacuated container at 1 atm, and the temperature remains constant at 0°c. (t1/2 = 23.9 min for 212rn.)
what is the partial pressure of the radon gas after this time?

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

part 1: which substance has a higher solubility?

a

smallest amount left undissolved atall temps in table shown most has dissolved high sol'by

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
