Unbalanced: C25H52 + O2 → CO2 + H2O
Balanced: C25H52 + 38 O2 → 25 CO2 + 26 H2O
Melting candle wax is a chemical change. Why? Because when you cook or burn candle wax it melts so it is a chemical change.
A chemical name for the main ingredient of a candle is "paraffin", but this is a generic chemical name and does not correspond to any exact formula. It can be written generically as CnH(2n + 2), where n represents a collection of positive integers that are all high enough for the compounds represented for a particular choice of n to be solids at room temperature.
The chemical energy stored in the candle wax.
The hardening of candle wax is a physical change. This is because the wax simply changes from a liquid to a solid state without any change in its chemical composition.
Heating a candle causes its wax to melt and burn, which involves a chemical reaction where the wax molecules are broken down and combine with oxygen in the air to produce heat, light, water vapor, and carbon dioxide. This transformation of wax into different compounds is a chemical change, as the composition of the candle wax is altered irreversibly during the process.

Some wax burns, and as it does so, chemical changes occurs. Wax converts to CO2, CO, and H2O. That is an exothermic reaction The rest of the wax melts with the increased temperature. That is the physical change.
The chemical energy stored in the candle wax.
The hardening of candle wax is a physical change. This is because the wax simply changes from a liquid to a solid state without any change in its chemical composition.
A candle converts chemical energy stored in the wax and wick into heat and light energy through combustion. The chemical energy in the candle is released as heat and light when the wax is burned, creating a flame.
A candle utilizes chemical energy stored within the wax. When the candle is burned, this chemical energy is converted into light and heat energy.

This transformation of wax into different compounds is a chemical change, as the composition of the candle wax is altered irreversibly during the process.
Candle wax typically reacts with oxygen in the air when it is burning, producing heat, light, and carbon dioxide. The chemical reaction that occurs during the burning of candle wax is called combustion.
Candle wax is a physical property since it is a characteristic of the substance itself. Physical properties describe the appearance, composition, and behavior of a material without changing its chemical composition.
The burning of a candle involves the chemical reaction of wax with oxygen to produce carbon dioxide and water. The general equation can be represented as: Wax (C25H52) + Oxygen (O2) -> Carbon dioxide (CO2) + Water (H2O) + Heat and Light.
