Define:Organic or Carboxylic acids
- compounds where molecules contain the-COOH group
Are these isomers or the same substance?a) CH3 - CH = CH - CH3
b) CH3 - C - CH3 II CH2
- Isomers
Define: alkene
- Hydrocarbons that contain a double bond
Define: polymer
- Substance whose large molecules are composed of many identical repeating units (500 to 20,000)
Define: alcohol
-Compounds that contain the -OH group.
Define: alkyne
- Hydrocarbons that contain a triple bond.
Define: alkane
- Hydrocarbons that contain only single bonds.
Define: Ether
-compounds containing the functional group
-O-
Define: Monomer
- Compounds whose molecules react to form (or build) polymers.
Define: Catalyst
- substance that speeds up a chemical reaction.
Define: Esters
-Compounds containing the
-COO-R group where R is a C and H group.
Define: unsaturated hydrocarbon
-Hydrocarbons with double and triple bonds. - they don’t contain the maximum number of hydrocarbons allowable.

What is the profile of a serial arsonist?
-feels power-loner-difficult time with relationships and jobs-Physical disorders
What is an accelerant?
Example…
-A petroleum product used to start or
enhance a fire -gasoline, kerosene, paint thinner
List some observations from the NOVA video.
-No common accelerant used-business types burned are the same (craft, furniture and fabric stores)-took place near a highway-point of origin was stuffing and
pillows-occurred near times of firefighter conferences-time delay device was a used (match, cigarette, rubber band with paper,)
What was the total U.S. energy consumption in 1950?(Fig. 22 pg. 235)
40 x 1015 kJ
What energy source was: a) used in 1925 in the greatest quantity?b) introduced in 1975?
(fig 22 pg. 235)
a) Coal
b) Nuclear
What are the disadvantages to alternative fueled vehicles?
-CNG compressor in fueling system is expensive.-Electric- initially more money, batteries are expensive, heavy and don’t last, recharging situations not in place yet.-H2/ Fuel Cell- manufacturing and operating costs are high, and high quality H2 is expensive.-Hybrid Gas/ Electric – Still produce some polluting emissions.
