Chemical reactions are very common in everyday life. When we turn on a gas stove, we are carrying out a combustion reaction, in which propane or butane gas combine with oxygen from the air to form carbon dioxide and water.

Another well-known reaction is the oxidation of Iron, its combination with oxygen from the air under appropriate conditions generates Iron oxide. This chemical reaction produces millions in losses, due to the rapid deterioration of tools, structures, etc.

There are very spectacular reactions, such as the one that takes place between Iron (III) oxide and aluminum metal (powdered), to produce liquid iron and aluminum oxide. This reaction gives off a large amount of heat, releasing products in the liquid phase. It is used to weld large iron structures and is known as thermite reaction.
