|
|
|
Charles-
|
V1/T1=V2/T2 -directly proportional
|
|
|
Combined-
|
VP/T=VP/t
|
|
|
Ideal-
|
Pv=nRt
|
|
|
In the ideal gas laws r stands for...
|
R=8.314 Kpa .0821 atm 62.4 mmHg
|
|
|
What is STP?
|
Standard Temp and Pressure
STP= 0*C 273K 1atm=760 mmHg= 101.3 Kpa |
|
|
Daltons law of partial pressures
|
Pt=P1+P2+P3
|
|
|
the kenetic molecular theory states
|
how tempurature and pressure all are inversley proportional
|
|
|
specific heat equation
|
Cp= q/m* deltT
|
|
|
what is specific heat?
|
Specific heat is the amount of energy required to raise on g of a substance one degree Celsius
|
|
|
what do the variables in the specific heat equation stand for?
|
q= amount of energy
m= mass deltT= temperature |
|
|
what is tempurature?
|
how fast the particles are moving in a substance
|
|
|
what is enthalpy?
|
Hprod(times coefficiants)-hreactants
|
|
|
If the _ is neggative it is exothermic if it is positive it is endothermic
|
deltH
|
|
|
Entropy is the amount of disorder in the system
What is the equation? |
deltG= deltH-TdeltS
When deltg is negative it is spontaneous |
|
|
Homogenous solutions
|
Homogeneous:
Solutions have the smallest particles Colloids have bigger particles look cloudy Suspension stays in solution but particles are pulled to the bottom |
|
|
Heterogenous solutions
|
solutions that are seperated like oil and vineger
|
|
|
when a solution is saturated it is
|
is when the solution is holding the most it can
|
|
|
when a solution is supersaturated it
|
is when it is holding more than it should
|
|
|
electrolytes are
|
is a substance in a solution that can conduct electricity
The things we taste in water are electrolytes |
|
|
equillibrium will sway
|
the way that relieves stress being applied
|
|
|
Keq= concentration of the products/concentration of the reactants
|
c^y d^z
------------- a^w b^x |
|
|
a mols is
|
is a count of something the mol is the unit of counting for mass of elements
|
|
|
Avagadro's number is
|
6.02x10^23
|
|
|
Molarity
|
Molarity= mols solute/ L of solution
|
|
|
