Key words Flashcards
Complete combustion
Plenty of oxygen
Alkene burns to produce carbon dioxide and water which releases a lot of energy
Incomplete combustion
Not enough oxygen
As well as carbon dioxide and water it also produces carbon monoxide and carbon (poisoness) less energy
Isomers
Two molecules with different structures but identical molecular formula
Cracking
Breaking down large hydrocarbon molecules into small hydrocarbon molecules
Polymerisation
Small molecules joining together to make longer chains. They are obtained by crude oil and more polymers can be made
Ionic bonding
The process where atoms lose or gain electrons to form charged particles
Oxidation
Atoms lose electrons
Reduction
Atoms gain electrons
Isotopes
Different atomic forms of the same element which has the same number of protons but different number of neutrons
Empirical formula
The simplest formula that tells you the ratio of differer elements in a compound
Molecular formula
The actual number of atoms of each element in a single molecule
Molecule
More than one atom
Compound
Different atoms bonded together
Homologous series
Group of compounds with the same the same general formula
