7

what is the specific heat of liquid water

1 calorie/ gram celcius

8

Heat capacity formula

q=mcAT

9

Kinetic molecular Theory of gases

1. particles have negligible Volume.
2. There e are no intermolecular attractions or repulsions.
3. Molecules ar ein continuous and random motion.
4. Collisions are elastic. Conservation of Kinetic Energy is observed.
5. The average kinetic energy of gas particles is proportional to the absolute temperature.

10

Daltons Law of partial pressures

In a mixture of gases, total pressure equals the sum of the pressures for each individual gas.
PA= XA Ptotal

11

Boyle's Law

at constant temperature, the volume of a gas is inversely proportional to its pressure
P1 V1= P2 V2

12

Charles's Law

at constant pressure, a gas volume is directly proportional to its temperature.
(V1/T1)= (V2/T2)

13

Avogadros' Law

The volume of a gas is directly proportional to the number of moles of the gas in.
(V1/n1)= (V2/n2)

R value is?

8.314 atm or 0.0831 J

16

Molarity (M)

Concentration
M= Moles of solute/ Liters of solutions

17

molality (m)

used for colligative properties
m= Moles of solute/ Kg of solvents

18

Dilution Formula

M1V1=M2V2

Henderson-Hasselbalch Equation

PH= Pka + log [Conjugate base/ weak acid]

POH= Pkb + log [Conjugate acid/weak base]

31

Reduction

Gain of electrons

32

Oxidation

Loose of electrons

33

Reducing agentCaO

Reduces something; becomes oxidized

34

Oxidation agent

Oxidizes something; becomes reduced

35

what are elastic collisions

elastic collision are those in which the colliding particle do not stick together and translational kinetic energy is not dissipated, such as those in an ideal gas.

36

Inelastic collisions occur between molecules in

real gases & fusions reactions.

37

according to the solubility rules which compounds are always soluble?

nitrates, alkali metals & ammonium

38

Solubility rules

1) All metal oxides are insoluble with the exception of CaO, SrO, BaO and alkali metal oxides.
2) Hydroxides are insoluble, with the exception of Ca+2, Sr+2, Ba+2 and the alkali metal hydroxides.
3) All sulfate salts are soluble exceptCa+2, Sr+2, Ba+2
