Question 6

Order the imfs in order of strongest to weakest

Answer 6

Hydrogen, dipole dipole, London dispersion

Question 7

Hydrogen bonding takes place when

Answer 7

Hydrogen is bonded to O,N, or F

Question 8

Dipole dipole takes place when…

Answer 8

You bond things together, and the Lewis structure is not symmetrical. One side is more negative

Question 9

How to tell if it is dipole dipole

Answer 9

Draw the Lewis structure, check electronegativity

How to tell if it is London dispersion

Answer 10

Draw the Lewis structure, if the charges are symmetrical then it is that.

Question 25

How to calculate the energy needed to change the temperature of something

Answer 25

Use q=mct

Question 26

Q equals

Answer 26

The energy required in joules

Question 27

M equals

Answer 27

Mass

Question 28

Delta t equals

Answer 28

Temperature change

Question 29

When can I use the calorimetry formula

Answer 29

When you are going up a slanted line.

Question 30

If there is zero temperature change then

Answer 30

The q=McAt will cancel out… Leaving just the fusion/vaporization calculation.

Question 31

C equals

Answer 31

The specific heat capacity (changes with the phase)

Question 32

How to use the fusion and vaporization heat. When do I use them

Answer 32

Multiply the mass by them, use it when you are going across a flat line.

Question 33

Having the lowest vapor pressure is the same as having

Answer 33

The highest imfs

Question 34

How to go from gas to liquid while finding the energy needed.

Answer 34

1. Use q=McAt to find the slanted line
2. Use the heat of fusion/vaporization for the flat lines,
3. Use q=McAt again if needed
4. Add together
5. 5 voilà
