Identify the reactants in the following chemical reaction: C₁₀H₈ + 12 O₂ → 10 CO₂ + 4 H₂O

Question

Quizplus · Accepted Answer

The reactants are the substances that undergo a chemical change in a reaction. In this case, the only substances listed on the left-hand side of the reaction (the reactants side) are C₁₀H₈ (a hydrocarbon called naphthalene) and 12 O₂ (oxygen gas). Thus, the correct choice is C, which includes both of these reactants. Choice A (C₁₀H₈ and 10 CO₂) and choice D (10 CO₂ and 4 H₂O) both include products as well as reactants, while choice B includes only products.
