Solution
The chemical reaction involved in the corrosion of iron metal is that of oxidation as well as combination.
Explanation:
During corrosion, iron metal reacts with oxygen gas in the presence of moisture to form hydrated iron(III) oxide (rust). This is an oxidation reaction because oxygen is added to the iron. It is also a combination reaction because multiple reactants (iron, oxygen, and water) fuse together to form a single compound.

Four metals P, Q, R and S are all obtained by the reduction of their oxides with carbon. Metal P is used to form a thin layer over the sheets of metal S to prevent its corrosion. Metal Q is used for electroplating tiffin boxes made of metal S whereas metal R is used in making car batteries. Metals Q and R form an alloy called solder. What are metals P, Q, R and S?
