Question 1

df amu

Answer 1

atomic mass unit- 1/12 of C12

Question 2

ep sub shells, obs

Answer 2

sub shell= spd eg 2P, orbital= eg 2Px 2Pz

Question 3

letter symbol mass num, proton num

Answer 3

A,Z

Question 4

nm 2 type ionization method

Answer 4

electrospray, e- impact

Question 5

ds 1st ionization method

Answer 5

electrospray: dissolve in solvent, apply hi V

V removes proton from solvent a adds it to sample compound

Question 6

sf electrospray

Answer 6

used 4 polymers, bio materials eg DNA

Question 7

ds 2nd ionization method

Answer 7

e- impact: vaporized, hit w e- from e- gun

e- hit e- off sample

Question 8

sf e- impact ionize

Answer 8

often causes sample to fragment

Question 9

ds dectects mass spect

Answer 9

ions hit - charged plate
causes current
size I used 2 ct how many mols hit plate

Question 10

interpret mass spectom d

Answer 10

tall peak= d on molecule of interest
nearby short peak= its isotopes
much lighter peak= compound produced from mol of interest being partly fragmented by pc
