Verified step by step guidance1
Identify the chemical equation given: 2 KClO3(s) → 2 KCl(s) + 3 O2(g).
Analyze the stoichiometry of the reaction: The coefficients in the balanced equation indicate the number of moles of each substance involved in the reaction.
Examine the oxygen atoms: The reactant side has 2 moles of KClO3, each containing 3 oxygen atoms, totaling 6 oxygen atoms. The product side has 3 moles of O2, each containing 2 oxygen atoms, also totaling 6 oxygen atoms.
Check the potassium atoms: There are 2 moles of KClO3 on the reactant side, each containing 1 potassium atom, totaling 2 potassium atoms. On the product side, there are 2 moles of KCl, each containing 1 potassium atom, also totaling 2 potassium atoms.
Verify the chlorine atoms: There are 2 moles of KClO3 on the reactant side, each containing 1 chlorine atom, totaling 2 chlorine atoms. On the product side, there are 2 moles of KCl, each containing 1 chlorine atom, also totaling 2 chlorine atoms.
