Term
Organic Compounds
Definition
A covalently bonded compound that contains carbon, excluding carbonates and oxides. Organic substances usually of animal or plant origin
Term
Hydrocarbons
Definition
Chemical compounds that consist entirely of carbon and hydrogen, such as petroleum, natural gas, and coal
Term
Combustion
Definition
an oxidation reaction of an organic compound in which heat is released
Term
Alkane
Definition
Compounds of carbon and hydrogen that contain single bonds
Term
Alkene
Definition
Compounds of carbon and hydrogen that contain double bonds
Term
Polymer
Definition
A large molecule made by linking smaller molecules (monomers) together
Term
Monomer
Definition
A molecule of low molecular weight capable of reacting with identical or different monomers to for polymers
Term
Biopolymers
Definition
Large compound molecule found within living organisms (such as protein, carbohydrate, or nucleic acid)
Term
Carbohydrates
Definition
A class of organic compounds including sugars and starches
Term
Proteins
Definition
A large organic molecule composed of more than 40 amino acid chains organized (folded) into complex structures
Term
Fossil Fuel
Definition
A nonrenewable energy source such as oil, gas, or coal that derives from the organic remains of past life. Fossil fuels consist primarily of hydrocarbons
Term
Methane
Definition
A colorless , flammable, odorless hydrocarbon gas (CH4) which is a major component of natural gas. It is also an important source of hydrogen, in various industrial processes.
Term
Ethylene
Definition
A flammable, colorless gaseous alkene; obtained from petroleum and natural gas and is used for manufacturing many other chemicals ; sometimes used in anesthetic . Ethylene is used for numerous chemical applications and the production of consumer goods such as plastic
Term
Amino Acids
Definition
The fundamental building blocks of a protein molecule. A protein is composed of a chain of hundreds or thousands of amino acids. Our bodies can synthesize most amino acids. However, eight amino acid (called essential amino acids) must be obtained from food
Term
Cross Linked
Definition
covalent bonds linking one polymer chain to another
Term
Polyethylene
Definition
a thermoplastic commodity heavily used in consumer products because of its property to become soft when heated and hard when cooled
Term
DNA
Definition
The large double-stranded molecule carrying the genetic code
Term
Carbon Bonding
Definition
The covalent bonds that carbon makes with other elements like hydrogen
Term
Carbon Sources
Definition
substances or places that produce or release carbon dioxide or other carbon products
Term
Carbon Sinks
Definition
areas or organisms that absorb, dissolve, or store carbon for later use by other things
Term
Isomer
Definition
molecules with identical chemical formulas but different molecular arrangements
Term
Byproducts
Definition
A secondary or additional product resulting from feedstock use of energy or the process of non-energy materials.
Term
Inorganic Compounds
Definition
Material such as sand, salt, and other minerals. Inorganic substances are of mineral origin, whereas organic substances are usually of animal or plant origins.
Term
Name 3 types of Hydrocarbon Bonds
Definition
alkane-1
alkene-2
alkyne-3
Term
Name three branches of carbon and give examples.
Definition
organic-from living things
inorganic-not from living things
synthtic- man made
Term
name 3 forms carbon makes and give examples of each
Definition
fullerene: hollow, absorbs heat
diomond: strong/compact/heat conductor
graphite: soft/slippery
Term
name 3 arangments of molecules and tell how they affect the properties
Definition
striaght/branched/rings/ ?
Term
name 3 main fossil fuels
Definition
coal,natural gas,crude oil
Term
What is fractional distillation?
Definition
to seperate/exctract parts of crude oil
Term
3 examples of things mad from crude oil
Definition
kerosene,diesel fuel,jet fuel
Term
What is the genral breakdown of crude oil?
Definition
50-gasoline
40-diesel fuel/kerosene/heating oil
10-redual fuel
Term
Explain how fractionation towers work
