A broader definition of corrosion is the destructive attack on a metal through interaction with its environment. It is the process by which metallic atoms leave the compounds in the presence of water or gas. Metal atoms leave the metal until it fails or erodes from oxidation.
The tendency for oxidation is dependent on the metal. Metals used in construction, such as steel and copper alloys, are both subject to corrosion. Metals are chemical combinations of multiple elements. These metals are highly vulnerable because of the high energy content of the elements used in metallic form. The energy content is higher than that of their ores, allowing corrosion to become a natural process. Through being present in their natural environments, the ores in the metal revert back to their original form. For example, iron in moist air becomes iron oxide.
The resulting rust is a generic term for when iron corrodes. The reaction between iron and water causes rust to form on a metal object.

Combination reaction also called synthesis reaction, the product will always be a compound.
For example:
A + B -> AB
C2 + O2 -> CO2
H2+Cl2 -> HCl
Energy was given out in the process as such the reaction must be exothermic given the loss of energy.
<h3>What is a reaction profile?</h3>
The reaction profile shows the the interaction between substances. Now the vertical axes shows the energy while the horizontal axes shows the course of the reaction. The hump at the top of the profile shows the activation energy. The activation energy is the maximum energy that is required for reactants to cross the barrier and become products.
Now we know that the endothermic reaction is one in which energy is taken in while an exothermic reaction is one in which energy is given out.
As such we can see from the graph that the energy of the reactants is greater than that of the products. This implies that energy was given out in the process as such the reaction must be exothermic given the loss of energy.
