- LiOH
- NaOH
- KOH
- CaOH2
- SrOH2
- BaOH2
2
Q
List strong acids:
A
- HClO4
- HCl
- HBr
- HI
- HNO3
- H2SO4
3
Q
List strong electrolytes:
A
- NaCl
- HNO3
- HClO3
- CaCl2
4
Q
List weak electrolytes:
A
- NH4
- H2CO3
- CH3COOH
5
Q
Solubility of SO4
A
ALWAYS except with Sr, Ba, Ag, Hg2, Pb
6
Q
Kinetic molecular theory of gases
A
- volume occupied by the molecule of the gas is negligible compared to the volume of the gas itself
- molecules of an ideal gas exert no attractive forces
- molecules are in constant random motion (until collision)
- collisions are perfectly elastic, but the total kinetic energy is conserved
- the average kinetic energy of the gas molecules is directly proportional to the absolute temperature
7
Q
Diffusion/Effusion
A
m1/m2 = (urms^2)/(urms^2)
8
Q
How do salts dissolve in a solution?
A
ionic bond pulled apart attraction of cation to O and anion to H
9
Q
Formal charge rules:
A
- smaller absolute formal charges are more favorable
- negative formal charges should be on the most electronegative atoms
- like charges should not be on adjacent atoms
10
Q
A Bronsted-Lowry acids is a […].
A
proton hydrogen ion donor
11
Q
A Bronsted-Lowry base is a […].
A
proton hydrogen ion acceptor
12
Q
Bronsted– In this theory, an acid is a…
A
substance that can release a proton
13
Q
Boyle’s Law:
A
PV=PV2
14
Q
Charles’s Law:
A
V1/T1 = V2/T2
15
Q
Avogadro’s Law:
A
V1/n1 = V2/n2
