Answer 12

-ate turns to -ic acid, -ite turns to -ous acid

Question 13

empirical formula

Answer 13

lowest relative number of atoms/moles of each element in a compound
to find: determine mass of each elemet, convert to moles as subscipts, convert subscipts to whole numbers

Question 14

molecular formula

Answer 14

actual number of atoms/molecules of each element in a compound

Question 15

molar ratio

Answer 15

found from balanced equation

Question 16

limiting reactant

Answer 16

reactant consumed first that determines the maximum amound of product that can form

Question 17

percent yield

Answer 17

actual yield/theoretical yield

Question 18

dilution

Answer 18

M1V1=M2V2

Question 19

Answer 19

moles of ion/volume of solute

Question 20

avogadro’s number

Answer 20

6.022 x 10^23

Question 21

soluble ionic compounds

Answer 21

attractions between ions and water molecules outweigh attractions between ions

Question 22

insoluble ionic compounds

Answer 22

attractions between ions is greater than the attraction between the ions and water

Question 23

molecular equation

Answer 23

shows reaction in solution in which reactant and products appear as intact, undissociated ions

Question 24

complete ionic equations

Answer 24

shows all soluble ionic substances dissolved into seperate ions

Question 25

net ionic equation

Answer 25

spectator ions have been eliminated to show actual change

Question 26

spectator ion

Answer 26

present as part of a reactant but not involved in the chemical change

Question 27

will a reaction occur is everything is soluble?

Answer 27

no precipate will form

Question 28

activity series

Answer 28

most active at the top, strongest reducing agent
elements, especially halogens, cannot replace elements above them

Question 29

products of combination

Answer 29

one compound

Question 30

products of decomposition

Answer 30

2+ products, at least one is an element

Question 31

products of double and single displacement

Answer 31

exhange places

Question 32

products of combustion

Answer 32

O2 + fuel -> H2O + CO2

Question 33

acid

Answer 33

produces H+ ions when dissolved in water
strong acid ionizes/dissociates completely

Question 34

base

Answer 34

produces OH- ions when dissolved in water
strong base ionizes/dissociates completely

Question 35

oxidation/oxidized

Answer 35

loss of electrons, increase in ON

Question 36

oxidizing agent

Answer 36

accepts electrons, decrease in ON

Question 37

reduction/reduced

Answer 37

gain of electrons, decrease in ON

Question 38

reducing agent

Answer 38

donates electrons, increase in ON

Question 39

oxidation number rules

Answer 39

element: 0
ion: charge, with sign before number
sum: 0 or charge
element in compound: alleged charge
