51
percent concentration (m/v) units
grams solute / ml solution times 100
52
percent m/m
grams solute/ grams TOTAL times 100
53
planck's quantum theory
the amount of a single quantum is this:
delta e= hv
h= 6.6 x 10^-34 js
54
when you are calculating the excited atom's energy, z is always
1 for hydrgen
55
go do some quantum theory practice on brains cape (it is unit 1)
HA
56
m in calorimetry is always in (units)
g
57
enthalpy of formation is
reactants -p
58
bond energy is
p-r
59
how to write rate law
it is r=k[a}order[b]order etc.
60
when to use integrated rate law
when you need to find the concentration after a certain time
61
writing the equilibrium expression (k)
first write the products to their coefficients/ reactants to their coefficients and only aq solutions are included
62
do some quantum practice
like the numbers
63
practice some hf and some bond energy stuff
yes
64
conjugate acid goes to
BASE by loosing an h
65
conjugate base goes to
acid by adding an h
66
name the strong acids
cl, br, i, h2so4, hno3
67
weak acid
ch3cooh, hf
68
how large will a strong acid's ka be?
very high
69
a weak acid equation
weak acid + water -- equilibrium-- hydronuim and a-
70

group 1 and 2 metal OH
71
weak base equatio
B+water--equilibrium--
72
basic ion
conjugate base of weak acid
73
acidic ion
conjugate acid
74
in any acid base problem
start with the chemical eon, then puzzle out an ice table, then write a k
75
oxidation numbers
oxygen is --2, except when it is r2o2 (then -1)
hydrogen is =1
all halogens have -1
76
cell potential
the half cell with the MORE POSITIVE e red will be reduced (the other will switch signs)
77
how to balance redox
```
split into half reactions
balance atoms not o and h
balance o by adding water
balance h by adding H+
add electrons to the more +ve side
cancel the electrons
```
78
high vp means
low imf
79
hydrogen bonding
is FON
80
plasma
noble gases + electricity
81
bose einstein
near absolute zero and becomes one “super particle”
82
what is the combined gas law
pv/t=pv/t
83
what is the ideal gas law
pv=nrt
84
go do the gas laws gr 11 practice cards
memorize the laws

when given separate gases with pressures and you mix them,
the pressures add up
86
what is stp
273.15 K (0 °C, 32 °F) and an absolute pressure of exactly 105 Pa (100 kPa, 1 bar).
87

m/v
88
quantum number things
n= 1,2,3 and is the energy level
l=0-(n-1) and s=0, p=1 etc. and s can have 1 orbital, p can have 3, d can have 5 etc.
