What type of chemical reaction occurs when a candle burns?

Explanation

Burning a candle is a combustion reaction, in which the wax, a hydrocarbon, reacts with oxygen in the air to produce carbon dioxide, water vapor, heat, and light. This exothermic reaction releases stored chemical energy as the candle wick draws up melted wax to fuel the flame. Combustion reactions are the basis for how most engines and power plants generate usable energy from fuel. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
