Chem 2 ACS final exam questions
and answers

Ans✔
p1v1=p2v2


Qs
gases are highly _________ - n
Ans✔
compressible


Qs

Ans✔
spontaneously


Qs

Ans✔
far apart in gases


Qs

,Ans✔
22.4 liters


Qs
the lighter the gas, _____ - n
Ans✔
the faster the effusion rate


Qs
the deviation from ideal behavior of a gas is most evident at high _____ and low
_____ - n
Ans✔
pressure, temp


Qs
Non reacting gas mixtures are homongeneous - n
Ans✔




Qs
normal melting point at - n
Ans✔
760 torr or 1 atm


Qs
the kinetic-molecular theory predicts that pressure rises as the temperature of a
gas increases because_______ - n
Ans✔
both the gas molecules collide more frequently with the wall and the gas molecules
collide more energetically with the wall

, Qs
hydrogen bonding - n
Ans✔
H with N,O,F


Qs
isothermal means - n
Ans✔
at constant temperature

Qs
the van der Waals equation - n
Ans✔
gas particles have non-zero volumes and interact with each other, molar volumes of
gases of different types are different, the non-zero volumes of gas particles
effectively decrease the amount of "empty" space between them, the molecular
attractions between particles of gas decreases the pressure exerted by the gas
