hybridization processs
count # of atoms
count # of lone pairs
atoms + lone pairs hybridization
6 sp^3 d2
5 sp^3 d
4 sp^3
3 sp^2
2 sp
1 s
from mm hg to atm
divide by 760 (atm)
from mm hg to bar
divide by 750.1
from mm hg to kilopascal
x by 0.1333
rate of difussion decreases when
molar mass increases
the gas with the lowest molecular weight will
effuse faster
Resonance structures what changes
the arrangement does NOT change
the only thing that moves is the lone pairs and double, triple bounds
how to draw resonance structures
draw lewis structures
Move lone pairs and double bond around to spread out the charge
if you move a lone pair into a multiple bond make sure the octet rule is respected
bond order average
of single bonds
eq resonance structures
all the structures are equally stable
non eq resonance structures
one resonance structure is better than the other
Most stable resonance structure
has the smallest formal charge and the charge is in the most electronegative atom
when filling orbital configuration
if d orbital is filed–> not include its valence and box
if d orbital is not filed–> include valence and box
limiting reagent
the smallest number of mols for reactants that we get by dividing the mass / MM to get moles and then dividing by stoich coefficient to get the limiting reagent
