What chemical change occurs when a wax candle burns?

Question

Quizplus · Accepted Answer

When a wax candle burns, the heat of the flame melts the wax near the wick. This liquid wax is then drawn up the wick to the heat source, where it eventually vaporizes and reacts with oxygen in the air. This reaction produces heat, light, water vapor, and carbon dioxide, and represents a chemical change. The products of this reaction (water vapor and carbon dioxide) are different from the wax and oxygen used as reactants, so this represents a chemical change rather than a physical change.
