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.
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
at constant temperature, the volume of a gas is inversely proportional to its pressure
P1 V1= P2 V2
at constant pressure, a gas volume is directly proportional to its temperature.
The volume of a gas is directly proportional to the number of moles of the gas in.
whats Standard Temperature and Pressure STP
R value is?
8.314 atm or 0.0831 J
M= Moles of solute/ Liters of solutions
used for colligative properties
m= Moles of solute/ Kg of solvents
Proton donor (H+)
Hydroxide ion donor (OH-)
electron pair acceptor
electron pair donor
Autoionization of water
Kw= [H+][OH-]= 1 x 10^ -14
Acid Dissociation constant
Ka= [A-][H3O+]/ [HA]
Base Dissociation Constant
Equivalence Point equation
VA NA= VB NB
PH= Pka + log [Conjugate base/ weak acid]
POH= Pkb + log [Conjugate acid/weak base]
Gain of electrons
Loose of electrons
Reduces something; becomes oxidized
Oxidizes something; becomes reduced
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.
Inelastic collisions occur between molecules in
real gases & fusions reactions.
according to the solubility rules which compounds are always soluble?
nitrates, alkali metals & ammonium
