Q

Strong acids

A

HCl, HBr, HI, HNO3, H2SO4

21
Q

weak acids

A

HF, H2CO3, H3PO4, CH3CO2H

22
Q

Oxidation rules (in order)

A
  • H=+1 (or -1 when bound to a metal)
  • O=-2
    *Halogens are -1
23
Q

Oxidized

A

loss of electrons, so the oxideation number becomes more positive

24
Q

Reduction/reduced

A

gain of electrons, so the oxidation number gets more negative

25
Q

oxidizing agent

A

the reactant that causes oxidation of another

26
Q

reducing agent

A

cthe reactant that causes reduction of another

27
Q

single displacement

A

a reaction in which one element is substituted for another element in a compound

28
Q

combustion

A

reactant with O2 forms CO2 + H20 as products

29
Q

percent yield

A

(actual/theoretical)x100

30
Q

kinetic energy

A

energy of movement

31
Q

potential energy

A

energy that is stored

32
Q

total energy +

A

U=q+w (total energy=heat+work)

33
Q

heat (q)

A

related to temp and how fast molecules are moving

34
Q

work (w)

A

related to displacement of an object

35
Q

endothermic

A

positive energy. Energy is required by system (energy is gained)

36
Q

exothermic

A

negative energy. energy is released by system (energy lost)

37
Q

system

A

the chemical reaction or smth else as defined

38
Q

surroundings

A

everything else besides system

39
Q

calorimetry formula thing

A

qsystem= -(qsurroundings)

40
Q

q=

A

MCchangeT (aka massspecific heatchange in temp)

41
Q

for delta T, what is the conversion of C to K

A

C=K ONLY for delta T

42
Q

enthalpy

A

delta H

43
Q

what is delta H measured in

A

KJ/mol

44
Q

Hess’s law

A

if you can add up the reactions, you can add up delta H values

45
Q

formation reaction requirements for hess’s law

A

forms 1 mole of product AND reactants are in elemental form

46
Q

standard enthalpy

A

the equation with delta H and summations and stuff
