Burning candles and the rusting of nails are examples of chemical changes owing to the fact that there are chemical reactions occurring and new chemical compounds are being formed as the reaction continues.
When a candle burns, the wax and wick of the candle are undergoing combustion and (ideally) being chemically changed into carbon dioxide and water, which are two completely new chemical substances than were present in the candle. In the case of the nail, iron in the steel alloy from which the nail is made is combining with oxygen to form a chemical compound not present in the nail, namely iron oxide.
