I got a great idea. cool
If anyone has a formula (try not to repeat ones already typed) then please add them to the list!
I think I good idea would be to make one post, and then if you want to add more, just EDIT it. This will save trouble serching over pages and pages of other people's notes!
By the way, I don't think "formula" is the right word... but look at my example, and just do something like it I guess... sweatdrop lol

METAL ---burns to form--> METAL OXIDE ---reacts with water to form-->BASE
NON-METAL ---burns to form--> NON-METAL OXIDE ---burns to form-->ACID
1= mono 2 =di 3= tri 4 =tetra 5= penta 6 =hexa 7= hepta 8= octa 9= nona 10=deca

Non metal+Non metal=covaliant bond
Metal+Non metal=ionic bond
Metal+Metal=matalic bond

In naming organic compounds:
1=meth, 2=eth, 3=prop, 4= but, 5=pent, 6=hex, 7=hept, 8=oct, 9=non, and 10=dec. Add -ane for single bonded compounds, -ene for double bonded compounds, and -yne for triple bonded compounds. That's the basic and it's too complicated to move onto more...
The Gas Laws:
Boyle's law
PV=k
Charles's law
V=kT
Gay-Lussac's law
P=kT
Combined gas law
(PV)/T=k
Ideal gas law
PV=nRT
P=pressure
V=volume
T=temperature
k=constant
n=numbers of moles
R=ideal gas constant

Methane, consisting of one carbon atom bonded to four hydrogen atoms has the chemical formula CH4
or sulfate, SO42-
or hydrogen peroxide, H2O2

Wow!
I need to get you guys to help me in my Chemistry, cuz I'm doing so bad right now.
gonk
What a great idea!

sun_charm Methane, consisting of one carbon atom bonded to four hydrogen atoms has the chemical formula CH4 or sulfate, SO42- or hydrogen peroxide, H2O2 In my school (the Dutch system), we have a little book called Binas full of information on Chemistry, Physics, Biology and Math. We get to use it at our tests and exams. It contains information on acid and base reactions, reaction equations, trivial names and the like. Mostly numers, but it's really useful!

The reason for the test isn't to get it right, but to understand what you are learning"

d = Distance
v = Velocity
v. = initial velocity
t = time
d. = initial distance
a = acceleration
d = d. + v*t
V = v. + a*t
If you want a challege use the following relation to derive the second formula from the first (a = dv/dt ; v = dd/dt)

What a great idea! How long do you have to take chemestry? Once you get the hang of it, Its easy

*Reserved for Fatal Crescent*
Hello! I'll be going through my old physics notes in a few weeks as I organize them and sell to incoming HS seniors, so yeah, I'll be posting some formulas here, seeing as we all post Chem here ^ ^

Strong oxidiser? Keep away from metal powders, organic fuels, halothanes.
Big 'ol unstable halogen? Keep away from ketones, aldehydes and all that crazy crap...
