Question What is the formula to convert from MOLES to GRAMS: Moles Grams
Answer 1 – 10 # moles X (molar mass/1 mole) = mass (g)
Question What is the formula to convert from GRAMS to MOLES Grams moles
Answer 1 – 20 Mass (g) X (1mole/molar mass) = # of moles
Question What is the mass of one mole of water?
Answer 1 – grams! Work: 2(2) + 16 = 18 grams

Question What is a mole?? Does a mole account for a large or small amount?
Answer 3 – 10 It is a counting unit for chemistry. It is a large (huge!) amount
Question What are hydrocarbons?
Answer 3 – 20 Molecular compounds that contain the elements HYDROGEN and CARBON only
Question What is an isomer?
Answer 3 – 30 It is a compound with the same MOLECULAR structure as another but with a DIFFERENT structure. – Example:
Question A catalyst does what? A basic example of a catalyst is when we introduce an ________ into a reaction.
Answer 3 – 40 Changes the rate of the reaction An enzyme
Question Combustion is?
Answer 3 – 50 A special type of oxidation that hydrocarbons go through
Question Is petroleum a renewable or nonrenewable resources? Crude oil is the same thing as: – Normal oil and gases – Fossils – Petroleum – Coal – Gasoline
Answer 4 – 10 Nonrenewable Petroleum
Question Why is crude oil superheated in the refinery process?
Answer 4 – 20 The hydrocarbons in the crude oil can be separated based on their boiling point.
Question When superheated (to boiling point), small hydrocarbon would have a __________ boiling point where as a larger hydrocarbon would have _________ boiling point. Low High
Answer 4 – 30 Small hydrocarbon is characterized by a low boiling point Large hydrocarbon is characterized by a high boiling point
Question We learned that petroleum in the refining process produces several distinctive mixtures called ______________ ? – Hint: We learned about 7 of those last week
Answer 4 – 40 Fraction
Question A petroleum is defined as what?
Answer 4 – 50 A collection of hydrocarbons of similar length found in the crude oil
Question What does the hydrotreating process remove from the hydrocarbon fractions?
Answer 5 – 10 It removes impurities: – Examples are sulfur, metals, and nitrogen
Question In naming organic compounds, an alkane is what??
Answer 5 – 20 Compounds with a single bond between carbon atoms
Question In naming organic compounds, what is an alkene?
Answer 5 – 30 Compounds with atleast one double bond between carbon atoms
Question What do we mean that a hydrocarbon can go through combustion? Why do hydrocarbons make good fuels?
Answer 5 – 40 We are burning it They produce a lot of energy when combusted
Question How do we know if a compound is organic or inorganic? Is H 2 O organic or inorganic?
Answer 5 – 50 It contains a carbon atom Inorganic
Section Alkanes know that alkanes are saturated hydrocarbons know that petroleum is a mixture consisting mainly of alkane hydrocarbons understand.
CARBON CHEMISTRY. THE BIG PICTURE CARBON COMPOUNDS Before 1828: Chemists believed compounds could only be divided two ways, into compounds they produced.

Using the methods of stoichiometry, we can measure the amounts of substances involved in chemical reactions and relate them to one another. Stoichiometry.
Types of reactions. What is a Chemical Reaction? A chemical reaction is the process by which one or more substances change into one or more new substances.
Organic Chemistry The study of Carbon and its compounds.
The. of and a to in is you that it he for.
Chemical reactions occur when bonds (between the electrons of atoms) are formed or broken Chemical reactions involve changes in the chemical composition.
Organic Chemistry IB. General Characteristics of Organic Molecules Organic chemistry is the branch of chemistry that studies carbon compounds. Biochemistry.
