Consider the following representation of a chemical change. 2 KClO₃(s) → 2 KCl (s)+ 3 O₂(g)
Which of the following correctly describes this process?

• A. There are two reactants and one product.
• B. The reaction involves the gas, liquid, and solid states.
• C. Oxygen and potassium chloride are the products of the reaction.
• D. Potassium chlorate and potassium chloride are the reactants in the reaction.

Answer: (C)

Verified step by step guidance

1. Identify the reactants and products in the chemical equation. The reactants are on the left side of the arrow, and the products are on the right side.
2. In the given equation, 2 KClO3(s) is the reactant, and 2 KCl(s) and 3 O2(g) are the products.
3. Determine the states of matter for each substance. KClO3 and KCl are solids (s), while O2 is a gas (g). There is no liquid state involved in this reaction.
4. Count the number of reactants and products. There is one reactant (KClO3) and two products (KCl and O2).
5. Based on the analysis, the correct description of the process is that oxygen (O2) and potassium chloride (KCl) are the products of the reaction, and potassium chlorate (KClO3) is the reactant.
