1. Not the first option because there are too many Oxygen molcecules on the right. ( 2O:  3O)

2. Not the second option because, again the oxygen's are not balanced. (6O:8O)

3.Correct! this is a balanced equation as there are equal amounts of all the molecules on each side of the reaction.

4. Not the fourth one because the Magnesium(Mg) are not balanced. (2Mg:1Mg)

The branch of science which deals with chemicals and bonds is called chemistry.

The correct answer is C

A balanced reaction is defined as the equal number of atoms present in the reactant and product.

According to the question, the correct balanced reaction is C that is.[tex]2 Fe_2O_3 + 3 C---> 4 Fe + 3 CO_2[/tex]

In this reaction, all the atoms are equal on both sides.

Hence, the correct option is C that is [tex]2 Fe_2O_3 + 3 C---> 4 Fe + 3 CO_2[/tex]
