Science10 Review) Flashcards
When would I use brackets on the polyatomic ions
Only when there’s more of them needed to make the charges balanced
What would I do to write hydrated ionic compounds
Name first part like normal then determine prefix number to word then do . (Prefix) H20
How do you name hydrated ionic compounds
Name first part like normal then write prefix and hydride
Magnesium sulfate heptahydrate
Name all prefixes used for molecular and hydrated ionic compounds
mono
Di
Tri
Tetra
Penta
Hexa
Hepta
Octa
Nona
Deca
When polyatomic ion what do you write
You have to write normal name no ide and charge that follows
Name all the acid prefixs
When ite – ous
When ide—hydro ic
When ate —ic
What’s Methane
CH4
What’s ammonia
NH3
What’s propane
C3H8
Ionic characteristics
- transfer
-conduct when in solution
-forms crystal lattice
-most soluble in water
-high melting point
Molecular characteristics
-don’t conduct when in solution
-doesn’t for crystal lattice
-most arnt soluble in water
-low melting point
How to find valance electrons
The group # or last digit
How to find energy levels
Period #
whats the product of hydrocarbon combustion
co2 and h2o
whats the formula for finding number of moles
n= m
——
M
how do you find M (molar mass)
you find the mass of all the elements in the equation then you times mass by times in equation then add all toghether
how do you find mass in an equation
m=(n)(M)
what does n stand for in the molar mass equations
the number of moles present
how many g are in kg
1000 g in 1kg
how many mmol in kmol
theres 10000000 in 1 kmol
how many ml in L
1000 ml in 1 L
how mant mg in g
1000mg in 1 g
