When iron rusts, solid iron reacts with gaseous oxygen to form solid iron(III) oxide. Write a balanced chemical equation for this reaction.
Here, we are going to write a balanced chemical equation for the given reaction.
A chemical equation represents a chemical reaction. It shows change of reactants to products through an arrow placed between them. The reactants are written on the left-hand side (LHS) with a plus sign (+) between them. Similarly, products are written on the right-hand side (RHS) with a plus sign (+) between them. The arrowhead points towards the products, and shows the direction of the reaction.
While writing a balanced chemical equation, the number of atoms of each element remains the same, before and after a chemical reaction.
