Answer 1

Higher ability to gain e-

Question 2

Ideal gas law

Answer 2

PV = n RT

Question 3

Electrons in products means

Answer 3

Oxidation potential

Question 4

Electrons in reactants

Answer 4

Reduction potential

Question 5

Electron flow is always from

Answer 5

Anode to cathode

Question 6

Reduction potential in ETC ____ with each subsequent step

Answer 6

Increases

Question 7

In spontaneous reactions the ___ reduction potential happens at cathode

Answer 7

Highest

Question 8

In spontaneous reactions the ___ reduction potential happens at anode

Answer 8

Lowest

Question 9

In electrolytic cell, which is non-spontaneous, the ___ reduction potential or _____ oxidation happens at anode

Answer 9

Higher reduction potential; lowest (whereas you would expect the highest reduction potential to be at cathode)

Question 10

Snell’s Law

Answer 10

n1 sin theta 1 = n 2 sin theta 2; n= speed of light in vacuum/medium

Question 11

Water has a higher indices of refraction than air because

Answer 11

Higher indices of refraction because light can bounce of more things in water

Question 12

What is an attacker?

Answer 12

Nucleophile

Question 13

When light enters something with higher indices (ice vs air) light will move

Answer 13

Towards the normal

Question 14

When light enters something with lower indices (from ice to water) light will move

Answer 14

Away from normal

Question 15

For lens, concave is

Answer 15

Diverging (light will go through 2 things)

Question 16

For lens, convex is

Answer 16

Converging (light will go through 2 things)

Question 17

In PV = nRT, P and V are ___ proportional

Answer 17

Are inversely proportional

Question 18

If you have an EWG, you have a ___ acid

Answer 18

Stronger

Question 19

Halides are ____ EWG’s

Answer 19

Weak

Question 20

Which theory of emotion includes cognitive interpretation?

Answer 20

Singer-Sanger

Question 21

Intermolecular forces are intensified when temp

Answer 21

Decreases; molecules don’t bounce off

Question 22

Water is a ____ nucleophile

Answer 22

Bad

Question 23

Ideal gases have negligible

Answer 23

V and intermolecular forces

Question 24

Mnemonic for EN

Answer 24

F O N Cl Br S C H

Question 25

Should ammeter be wired in series or in parallel?

Answer 25

Series

Question 26

If you have non-negligible resistance, your current will

Answer 26

Increase (V = IR, I = V/R)

Question 27

When delta G is -, emf is

Answer 27

+

Question 28

Sound waves are

Answer 28

Longitudinal

Question 29

Sound waves travel ______ in solid

Answer 29

Faster

Question 30

Bulk modulus is ____ in solid

Answer 30

Greater

Question 31

Electric potential formula

Answer 31

V = kq/r

Question 32

Electric field formula

Answer 32

F/q (F = kqQ/r^2) so if you plug that in then (kqQ/r^2)/q = K Q/r^2

Question 33

Calculating EMF from perspective of reduction potential

Answer 33

E cell = E cathode - E anode (you HAVE to do this from reduction potential and)

Question 34

What is another way to find E cell other than from perspective of reduction potential?

Answer 34

E cell = E reduction + E oxidation

Question 35

Bulk modulus

Answer 35

How stiff something is; greater in steel than air

Question 36

In electrolytic cell, which is non-spontaneous, the ___ reduction potential or _____ oxidation happens at cathode

Answer 36

Lower; higher oxidation (whereas you would expect the lower reduction potential and higher oxidation potential to happen at anode)
