Chem/Phys Flashcards
Increased reduction potential means
Higher ability to gain e-
Ideal gas law
PV = n RT
Electrons in products means
Oxidation potential
Electrons in reactants
Reduction potential
Electron flow is always from
Anode to cathode
Reduction potential in ETC ____ with each subsequent step
Increases
In spontaneous reactions the ___ reduction potential happens at cathode
Highest
In spontaneous reactions the ___ reduction potential happens at anode
Lowest
In electrolytic cell, which is non-spontaneous, the ___ reduction potential or _____ oxidation happens at anode
Higher reduction potential; lowest (whereas you would expect the highest reduction potential to be at cathode)
Snell’s Law
n1 sin theta 1 = n 2 sin theta 2; n= speed of light in vacuum/medium
Water has a higher indices of refraction than air because
Higher indices of refraction because light can bounce of more things in water
What is an attacker?
Nucleophile
When light enters something with higher indices (ice vs air) light will move
Towards the normal
When light enters something with lower indices (from ice to water) light will move
Away from normal
For lens, concave is
Diverging (light will go through 2 things)
For lens, convex is
Converging (light will go through 2 things)
In PV = nRT, P and V are ___ proportional
Are inversely proportional
If you have an EWG, you have a ___ acid
Stronger
Halides are ____ EWG’s
Weak
Which theory of emotion includes cognitive interpretation?
Singer-Sanger
Intermolecular forces are intensified when temp
Decreases; molecules don’t bounce off
Water is a ____ nucleophile
Bad
Ideal gases have negligible
V and intermolecular forces
Mnemonic for EN
F O N Cl Br S C H
Should ammeter be wired in series or in parallel?
Series
If you have non-negligible resistance, your current will
Increase (V = IR, I = V/R)
When delta G is -, emf is
+
Sound waves are
Longitudinal
Sound waves travel ______ in solid
Faster
Bulk modulus is ____ in solid
Greater
Electric potential formula
V = kq/r
Electric field formula
F/q (F = kqQ/r^2) so if you plug that in then (kqQ/r^2)/q = K Q/r^2
Calculating EMF from perspective of reduction potential
E cell = E cathode - E anode (you HAVE to do this from reduction potential and)
What is another way to find E cell other than from perspective of reduction potential?
E cell = E reduction + E oxidation
Bulk modulus
How stiff something is; greater in steel than air
In electrolytic cell, which is non-spontaneous, the ___ reduction potential or _____ oxidation happens at cathode
Lower; higher oxidation (whereas you would expect the lower reduction potential and higher oxidation potential to happen at anode)
