Question

what do the chemical reactions that occur during burning and rusting have in common

Answer 1

Rusting refers to a chemical reaction when a metal, in the majority of the cases, iron, reacts with water vapor and oxygen to get transformed into a metal oxide, like iron oxide. Burning is also a chemical reaction, which involves a fuel and oxygen. It discharged high amount of energy in the form of heat.  

Both burning and rusting are examples of oxidation reactions and exhibits oxygen as the oxidizing agent.  

Answer 2

Explanation:

The chemical reactions that occur during burning and rusting have the process of oxidation in common.

As oxidation is a process where there is loss of electrons or addition of oxygen atom.

For example, the chemical reaction occurring in rusting is as follows.

          $Fe^{2+} + O_{2} \rightarrow Fe_{2}O_{3}$

Here, Fe losses an electron and oxygen gains that one electron as a result, there is formation of iron (III) oxide.

In a burning reaction, the process of oxidation also occurs.

For example, the chemical reaction occurring when carbon is burnt in oxygen is as follows.

        $C + O_{2} \rightarrow CO_{2}$

In this process, addition of oxygen displays that oxidation is taking place.
