Combustion reaction
Synthesis
exothermic
rapid oxidation aka combustion aka burning process
displacement reaction
Na2O + H2O ---> 2NaOH this is a metal oxide (base) reacting with water to form an alkali
neutralisation reaction
It is a neutralistion reaction.
decomposition reaction
This is an oxidation-reduction reaction.
It is an eothermic type of reaction.
This is an double-displacement reaction, in this case and acid-base reaction.
decomposition
Synthesis
exothermic
single replacement
That is a synthesis reaction, also called a combination reaction.
Decomposition
