The reaction 2KClO3 --> 2KCl + 3O2 is a decomposition reaction, where a single compound breaks down into two or more simpler substances.
Combustion reaction
An acid plus a base will yield a salt and water in a neutralization reaction.
This reaction is called "metal-metal exchange reaction".
This is a single displacement reaction, specifically a redox reaction. In this reaction, iron displaces copper from copper sulfate to form iron sulfate and copper.
Na2O + H2O ---> 2NaOH this is a metal oxide (base) reacting with water to form an alkali
this is an exotermic reaction
Displacement reaction
This is an oxidation-reduction reaction.
A double replacement reaction.
This is an double-displacement reaction, in this case and acid-base reaction.
It is an eothermic type of reaction.
decomposition reaction
Combustion reaction
An acid plus a base will yield a salt and water in a neutralization reaction.
This reaction is called "metal-metal exchange reaction".
kraker
This is an acid-base reaction or proton exchange, but there are many more reaction possibillities depending of Cu2+, OH- and NH3 concentration
