1.Lithium has the greater ionization energy
2. Vanadium has a greater ionization energy
Answer:
Liquid - Gas is Evaporation & Gas - Cooling is condensation
Explanation:
Molecular are only between non-metals. Ionic has a higher melting point
Answer:
volume is equal to the mass divided by the density (V = M/d).
From the ideal gas law
pv=nRT , n is therefore PV/RT
R is the
R is gas constant =62.364 torr/mol/k
P=500torr
V=4.00l
T=500+273=773k
n={(500 torr x 4.00l)/(62.364 x773k)}=0.041moles
the number of molecules=moles x avorgadro costant that is 6.022x10^23)
6.022 x 10^23) x0.041=2.469 x10^22molecules
