Combustion
A reaction in which a fuel combines with oxygen and gives out energy and a flame.
Exothermic
A reaction which gives out energy (gets hotter).
Endothermic

Decomposition
A reaction in which a compound is broken down into simpler substances.
Thermal Decomposition
A reaction in which a compound is broken down by heat into simpler substances.
Synthesis
A reaction in which two or more substances combine to form a more complex product.
Displacement
A reaction in which a more reactive element takes the place of a less reactive element in a compound.
Effervescence
A fizzing made when gas is produced.
Precipitate
