No
What is the atomic number of Antimony?
51
- Melting point of 320 C

-Conducts electricity in an aqueous solution
According to Gay-Lussac's Law, is the pressure of a gas inversely proportional or proportional to it's temperature?
Proportional
In low volume / high pressure containers, can gas molecules have IMFs?
Yes because the low volume and high pressure forces them to interact.
Do saturated solutions contain a lot of solute/super concentrated?
Yes

a) H2 b)O2 c) Xe d) F2 e)N2
a) H2

a) The denisty b) The pressure c) The average velocity
d) The number of molecules per cm
B) the pressure
Ar deviates from ideal behavior at higher pressures compared to Ne, why?
a) Ar has a greater volume
b) Ar has more valence electrons
c) The intermolecular forces of Ne are greater than Ar
a) Ar has a greater volume
