see early post for a larger variety of tutorials/videos on balancing equations.

Stoichiometry:
Deals with the calculations about the masses of reactants and products involved in a chemical reaction. It allows us to know how much of an element or reactant to use and how much product is expected to come out of the reaction.

Chemical Reactions
Combustion Reactions:
These reactions occur when organic molecules react with oxygen gas (O2). This is also called burning. You need three things in order to burn something:

• a fuel (hydrocarbon)
• oxygen to burn it with
• Something to ignite the reaction (spark)

Products in the combustion are Carbon dioxide and H2O. Combustion is a type of oxidation reduction reaction.

Reactions of Organic Molecules

Hydrogenation is the reduction of alkenes. During Hydrogenation, the carbon atoms in an alkene are reduced because they gain hydrogen atoms.

Hydrolysis involves water that is used to split (lyse) a molecule. Esters undergo hydrolysis. Hydrolysis is one of the factors that determines the length of time that some drugs remain active.

Hydration of an Alkene. I

n a hydration reaction, water is added to a double bond.

Dehydration is the reverse of hydration. Water is removed from an alcohol to form a double bond (alkene)http://www.chemguide.co.uk/mechanisms/elim/dhethanol.html#top

Specific Heat
http://videos.howstuffworks.com/hsw/20991-chemistry-connections-heat-capacity-and-calorimetry-video.htm
Q=S (specific heat) x M (mass) x delta T (final temperature - initial temperature)
M=Q/delta T x S
delta T=Q/M x S
S=Q/M x delta T

Boyle's Law

Boyle's Law states that at constant temperature the pressure of the gas times its volume will remain constant

Looking for final volume? V2=P1V1/P2

Looking for final pressure?P2=P1V1/V2

Gay Lussac's Law
As temperature increases, pressure increases adn vice versa.

Charles Law

As temperature increases, the volume increases and vice versa
"Charles is under constant pressure"

Equations: Remember...you must use Kelvin
V2=T2V1/T1
T2=T1V2/V1

Combined Gas Law:
relationship between temperature, volume and pressure.http://web.fccj.edu/~ksanchez/flash/corwin/ComGasLaw.html

V2=T2P1V1/P2T1

T2=P2V2Ti/P1V1

P2=P1V1T2/T1V2

Avogadro's Law and Ideal Gas Law

Avogadros Law:

The direct relationshoip between moles of gas molecules and volume. When the number of moles of gas increases, the volume increases. Pressure and temperature never change.

V2=N2V1/N1

N2=N1V2/V1
