General formula
A type of formula that represents the composition of any member of an homologous series
17 of 31
Homologous series
A family of compounds with similar chemical properties and gradual variation in physical properties. They have the same general formula with successive members differing in their molecular formulae

21 of 31
Combustion
A chemical reaction in which a compound reacts with oxygen
22 of 31
Complete combustion
Combustion of hydrocarbons with enough oxygen present to convert all the fuel into carbon dioxide and water
23 of 31
Haemoglobin
The red, iron-containing pigment found in the red blood cells
24 of 31
Incomplete combustion
When a substance reacts only partially with oxygen, such as when carbon burns in air producing carbon monoxide and soot (unburnt carbon)
25 of 31
Oxidation
A reaction in which oxygen is added to a substance
26 of 31
Red blood cells
A biconcave disc containing a haemoglobin that gives blood its red colour and carries oxygen around the body to the tissues. Also known as an erythrocyte
27 of 31
Soot
