Physics wk3 Flashcards
When a system in a state of dynamic equilibrium is disturbed, it will react to re-establish the equilibrium condition is what principle?
Le chatelier’s principle
a state of equilibrium is when there is
balance between the reactants and products
Thermodynamics defines
state of equilibrium
As K increases, the reaction tends to increasingly favor the
products
as K decreases the reaction tends to increasingly favor
starting materials
if you ADD products, the equilibrium will shift toward
reactants
if you REMOVE products, the equilibrium will shift towards
products
when an acid donates a proton, it is converted into its
conjugate base
when a base accepts a proton, it is converted into its
conjugate acid
behaves as either an acid or a base
amphoteric species
the stronger the acid, the _______ the conjugate base
weaker
the weaker the acid, the _______ the conjugate base
stronger
a stronger acid is more determined to give
its proton to some base
a stronger base is more determined to
take a proton from some acid
T/F weak acids do not ionize 100% in water
true
when the concentration of a weak acid and its conjugate base are equal, the pH is equal to the
pKa
soda lime can absorb
23L of CO2 for every 100 grams of absorbant
optimal size of soda lime pebbles
2.5mm or 4-8 screen mesh
soda lime pack and change
loose and before machine check
what causes pH sensitivity dye changes
colbarnic acid
what law is pulse oximetry based on
Beer Lambert Law
wave length of red light pulse ox
660nm
wave lenght of infrared light pulse ox
940nm
how does pulse ox work
changes in absorption of light through pulse of vascular bed, log equation, predicts oxygen saturation
