1. C ARBON C HEMISTRY Ch 9.

2. TrueFalseStatementTrueFalse Organic compounds contain carbon and oxygen Saturated hydrocarbons contain multiple bonds Unsaturated hydrocarbons contain only single bonds Fossil fuels are hydrocarbons from remains of plants and animals Diamonds are a form of carbon

3. C ARBON Organic Compound Contains carbon and hydrogen Forms of Carbon Diamond Graphite Fullerenes

4. S ATURATED H YDROCARBON Straight Chain Branched Chain Rings All bonds are single bonds Also called alkane

5. U NSATURATED H YDROCARBON Alkenes Alkynes Aromatic Hydrocarbon Contain 1 or more double or triple bond

6. F OSSIL F UELS Mix of hydrocarbon formed from the remains of plants and animals Coal Natural Gas Petroleum

7. P ROTEINS, E NZYMES AND V ITAMINS Protein Polymer which 100 amino acid monomers are linked by a carboxyl group Amino acids- compound with carboxyl and amino acid Enzymes Proteins that act as catalysts for reactions in cells Vitamins- organic compounds that animals need, but cant produce

9. TrueFalseStatementTrueFalse There are 3 types of radiation: alpha, gamma, and nuclear A half life is the time for half of a sample to decay Radioactive dating, tells us the date of items from years ago Fission is when smaller parts make a larger mass and energy Fusion is when a large part breaks down into smaller parts and energy

10. N UCLEAR D ECAY Radioactivity Process which unstable atomic nucleus emits charged particles and energy Types Alpha Decay Positively charged 2 p and 2 n +2 charge Uranium 238 decay Beta Decay Negatively charged Thorium 234 decay Gamma Decay Ray of energy Emitted by unstable nucleus

11. H ALF L IFE Time required for one half of a sample of radioactive material to decay Radioactive Dating Age of old objects are determined by comparing the objects carbon 14 levels with that in the atmosphere

12. N UCLEAR F ORCES Splitting of atomic nucleus into 2 smaller parts Tremendous amounts of energy are produced from tiny amounts of mass Creates nuclear energy, and bombs Nuclei of 2 atoms combine to form a large nucleus Requires high temperatures Plasma Atoms are stripped of electrons FissionFusion
