Answer:
CH3NH2 : Hydrogen bonding and London dispersion forces
F2 : Hydrogen bonding, dipole-dipole and London dispersion forces
NOF : Dipole-dipole forces
C2H6 : London dispersion forces
H2O : Hydrogen bonding and London dispersion forces
Increasing order of boiling point:
F2
C2H6
NOF
CH3NH2
H20
Explanation:
London dispersion forces exist in all substances
CH3NH2 : The hydrogen bonding in the amine group and the assymetry of the molecule makes the hydrogen bonding and dipole-dipole bonds from the methyl group.
F2 : The bond is non polar because its a homonuclear bond
NOF : Dipole-dipole forces due to difference in elecronegativity between all the atoms involved and assymetry
C2H6 : London dispersion forces because all dipole-dipole forces are cancelled out due to the symmetry of the molecule
H2O : Hydrogen bonding between hydrogen and oxygen and the assymetry of the molecule
Order of boiling points: London dispersion forces, followed by dipole-dipole forces and hydrogen bonding is the strongest
Answer: 
Hz
Explanation: Recall the formula for the speed of light is
where 
is the speed of light,
is the wavelength, and 
is the frequency. Assuming this takes place in a vacuum, 
m/s. Now we can solve for frequency
(rounding to 3 sig figs)
Thus, the frequencyis Hz.
Answer:
The final volume will be 24.7 cm³
Explanation:
<u>Step 1:</u> Data given:
Initial temperature = 180 °C
initial volume = 13 cm³ = 13 mL
The mixture is heated to a fina,l temperature of 587 °C
Pressure and amount = constant
<u>Step 2: </u>Calculate final volume
V1/T1 = V2/T2
with V1 = the initial volume V1 = 13 mL = 13*10^-3
with T1 = the initial temperature = 180 °C = 453 Kelvin
with V2 = the final volume = TO BE DETERMINED
with T2 = the final temperature = 587 °C = 860 Kelvin
V2 = (V1*T2)/T1
V2 = (13 mL *860 Kelvin) /453 Kelvin
V2 = 24.68 mL = 24.7 cm³
The final volume will be 24.7 cm³
