When zinc metal reacts with oxygen gas, 2Zn(s) + O2(g) → 2ZnO(g), large amounts of light and heat are released. A student states that this reaction is a combustion reaction but
not a redox reaction. Do you agree? Defend your answer by explaining whether or not it
meets the requirements of each type of reaction.
