Chem Second Final Flashcards
Kinetic Molecular Theory
1) Gases made up of tiny particles in constant motion
2) When particles collide with wall f container, pressure is formed
what is STP
1 atm, 273 K (O Celsius)
Boyle’s Law
vol inversely to press
Charle’s Law
Vol directly to temp
Avogadro’s
vol directly to moles
what is a super saturated solution
to much solute, cloudy
what is a solute
thing that gets dissolved
what is a solvent
thing that dissolves
what is a solution
solvent+solute
How to increase dissolving
1)increase temp 2) stir
Colligative Properties
depends on number of molecules, not type
When concentration increases, boiling point and freezing point____
boiling point goes up, freezing goes down
what is titration
indicator used to show when at acid and base are equal
When you add a substance/heat
it shifts away from reaction
What is fission
splitting of atom’s nucleus
What is fusion
combining of nuclei
What is half life of C14
5730 years
What is an isomer
same molecular formula, different arrangement of atoms
Polymer
large chain of monomers
monomers
smaller subunits of polymers
when Pressure goes up volume goes
volume goes down
When temperature goes up volume goes
volume goes down
what is a weak acid/base
does not completely dissociate
oxidation example
Na - > Na+ + e-
reduction example
Cl + e- -> Cl-
How to increase rxn rates
1)increase concentration 2) temperature 3) surface area
Double conc:
0 = rate unchanged
1 = rate doubles
2= ratex4
3=tripled
Electromagnetic Radiation
energy transfer by light
