Why are burning candles and rusting nails examples of chemical change?

Burning candles and rusting nails are both examples of chemical change because they both involve redistribution of electrons. In burning of candles electrons that were shared between carbon and hydrogen atoms are now shared with oxygen atoms. In rusting electrons belonging to iron atoms are donated to oxygen atoms.

Was this reaction exothermic or endothermic?

Energy Diagrams

Endothermic Reactions Exothermic Reactions
Heat is absorbed by reactants to form products. Heat is released.
Heat is absorbed from the surroundings; as a result, the surroundings get cold. Heat is released by the reaction to surroundings; surroundings feel hot.
ΔHrxn is positive ΔHrxn is negative
