Answer: This reaction is a type of synthesis reaction.
Explanation: When iron reacts with oxygen which is available in air, it leads to the formation of a reddish-brown compound known as rust.
This reaction is considered as oxidation-reduction reaction because iron is getting oxidized to [tex]Fe^{2+}[/tex] and oxygen is getting reduced to oxide ion.
Equation of the rust follows:
[tex]4Fe(s)+3O_2(g)+nH_2O(l)\rightarrow 2Fe_2O_3.nH_2O[/tex]
Synthesis reactions are defined as the reactions in which two or more than two reactants combine together to form a single product which can be a molecule or a compound.
The rusting of iron is also considered as a synthesis reaction because iron and oxygen are combining together to form a single compound known as rust.
Both these reactions are a type of Chemical reactions.
