Answer
The balanced equation for the reaction is:
.
Explanation
This question is regarding a chemical reaction where iron oxide reacts with carbon to form iron and carbon dioxide. This is a fundamental and typical example of a metallurgical process (reduction of ore) wherein a metallic oxide is reduced to the metallic state using a suitable reagent. To balance an equation it is necessary to make the number and type of atoms on the left side of the equation equal to the number and type of atoms on the right side. In this reaction, 2 moles of iron oxide react with 3 moles of carbon to produce 4 moles of iron and 3 moles of carbon dioxide, satisfying the requirement that the number of atoms of each kind should remain conserved or constant both before and after the reaction.
