The   volume  of  ideal gas  that would   occupy  at 1.50 atm  and 216 c is

2016.49 ml


<u><em>calculation</em></u>

  • volume is  calculated using a  combined  gas equation

  that is P1V1/T1=  P2V2/T2

 P1( pressure 1) =  7.20  atm

V1 ( volume 1) = 250  ml

T1 ( temperature 1) = 18 + 273=291  K

P2 ( pressure 2) = 1.50 atm

T2 ( temperature 2)= 216+273=489 K

V2  (  volume 2) =?

  • by   making V2 the subject  of the  formula  

 V2=[(T2 xP1 x V1)/(T1 xP2)]

V2=[ (489 K  x 7.20 atm  x 250 ml)   / ( 291 k  x 1.50 atm)] =  2016.49  Ml

You haven't attached any options but anyways, to help you with your question, elements belonging to the same group (e.g. alkali metals, noble gases) all have the same chemical properties. Hydrogen, for example, have the same properties with Sodium, Potassium and Lithium.

Hydrophobic compounds dissolve in
Anastaziya [24]
Hydrophobic molecules tend to be nonpolar molecules that group together to form micelles rather than be exposed to water. Hydrophobic molecules typically dissolve in nonpolar solvents (e.g., organic solvents).
