Solution

Balanced chemical equation:

  • A balanced chemical equation is an equation where the number of atoms in the reactant and the product side should be an equal number.
  • It can be balanced by using coefficients in front of reactant or product species..

Chemical Reaction:

  • Iron (III) oxide reacts with carbon monoxide to form solid iron and carbon dioxide gas as follows:

Fe2O3(s)+3CO(g)2Fe(s)+3CO2(g)

  • The above reaction is an example of a redox reaction because both the removal and addition of hydrogen and oxygen happen.

Redox reaction:

  • A redox reaction is a chemical process that involves the exchange of electrons between two reactants. This electron transfer can be identified by changes in the oxidation states of the reacting species.
  • Redox is a combination of oxidation and reduction reactions.
