Question

a student writes the chemical equation for rusting: 4fe + 3o₂ → 2fe₂o₃ what does this balanced equation show? iron atoms are destroyed when rust forms. the total number of each type of atom is equal on both sides. oxygen atoms are created during the reaction. the mass of the reactants is greater than the mass of the products.

Explanation:

In a balanced chemical equation, the law of conservation of mass is obeyed. This means the total number of each type of atom on the reactant side is equal to the total number of that type of atom on the product side. Atoms are neither created nor destroyed in a chemical reaction.

Answer:

The total number of each type of atom is equal on both sides.
