ch 4

Question 1

strong acids

Answer 1

I
Br
SO4
NO3
Cl
ClO3
ClO4

I BRought SOrry NO Cl ClO3 ClO4

Question 2

theoretical yield

Answer 2

seeing limiting reactant, how much can possibly be produced?

Question 3

percent yield

Answer 3

actual yield
—————– x 100
theoretical

Question 4

nonpolar vs polar

Answer 4

non: symmetrical dis of charge
polar: asymmetrical dis of charge

Question 5

what solute-solute interactions make unable to dissolve? what would make able to dissolve?

Answer 5

STRONGER solute-solute interactions than solvent-solute= not dissolve

WEAKER solute-solute interactions than solvent-solute= dissolves

Question 6

electrolyte vs. non-electrolyte

Answer 6

electrolytes:
substances that dissolve in water to form solutions that conduct electricity because of FREELY MOVING IONS

non-electrolytes:
substances that dissolve in water to form solutions that do NOT conduct electricity because of NO FREELY MOVING IONS

Question 7

strong vs weak electrolytes

Answer 7

strong: completely dissociate
weak: partially dissociate

Question 8

precipitation reactions

Answer 8

double replacement where solid (precipitate) forms

only insoluble compounds form precipitates

Question 9

net ionic vs complete ionic equation

Answer 9

complete ionic: shows all species as they are present (charges and separate all AQ solutions (weak acids and polyatomic ions together))
net ionic: shows species that actually CHANGE during reaction

Question 10

strong bases

Answer 10

group 1 except Fr (ex: NaOH, KOH, etc.)
Group 2A middle 3: Ca, Sr, Ba CBS!

Question 11

oxidation and oxidizing agent
reduction and reducing agent

Answer 11

O: losing electrons
OA: species that is REDUCED (helps oxidize)

R: gaining electrons
RA: species that is OXIDIZED (helps reduce)

Question 12

charge of O2 in ionic compound

Answer 12

-1
ex: K2O2
K has charge of +1
O has charge of -1
