Final answer:
The equation 2 KClO₃ → 2KCl + 3O₂ is a balanced chemical equation because it has the same number of each type of atom on both sides of the arrow, following the law of conservation of mass.
Step-by-step explanation:
The chemical equation provided, 2 KClO₃ → 2KCl + 3O₂, is indeed a balanced chemical equation. Each element has the same number of atoms on both the reactant and product sides of the equation, which is the requirement for a chemical equation to be considered balanced. This type of equation represents a chemical reaction where potassium chlorate decomposes into potassium chloride and oxygen gas. It is not an unbalanced chemical equation, nuclear equation, or ionic equation. The process of balancing chemical equations ensures that the law of conservation of mass is obeyed, as the mass of the reactants must equal the mass of the products.
