Question 6

Kinetic molecular theory of gases

Answer 6

1. volume occupied by the molecule of the gas is negligible compared to the volume of the gas itself
2. molecules of an ideal gas exert no attractive forces
3. molecules are in constant random motion (until collision)
4. collisions are perfectly elastic, but the total kinetic energy is conserved
5. the average kinetic energy of the gas molecules is directly proportional to the absolute temperature

Question 7

Diffusion/Effusion

Answer 7

m1/m2 = (urms^2)/(urms^2)

Question 8

How do salts dissolve in a solution?

Answer 8

ionic bond pulled apart attraction of cation to O and anion to H

Formal charge rules:

Answer 9

1. smaller absolute formal charges are more favorable
2. negative formal charges should be on the most electronegative atoms
3. like charges should not be on adjacent atoms
