The combustion reaction of a candle can be represented by the equation: C25H52 + 38O2 → 25CO2 + 26H2O. This equation shows the burning of the paraffin wax (C25H52) in the presence of oxygen (O2) to produce carbon dioxide (CO2) and water (H2O) as the main products of combustion.
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.
Unbalanced: C25H52 + O2 → CO2 + H2O Balanced: C25H52 + 38 O2 → 25 CO2 + 26 H2O
The balanced chemical equation for a burned candle is C25H52 (wax) + O2 (oxygen) -> CO2 (carbon dioxide) + H2O (water) + heat. This represents the combustion reaction that occurs when a candle burns, turning the wax and oxygen into carbon dioxide, water vapor, and releasing heat.
When a candle is burned, it undergoes combustion to produce carbon dioxide and water vapor. The balanced reaction equation for the combustion of a candle can be represented as: Candle wax (C25H52) + 38 O2 → 25 CO2 + 26 H2O

I assume you're talking about burning a candle. Nope, it's a chemical change. Candle wax is a chemical, and when you burn the candle, the wax reacts with oxygen in the air to produce carbon dioxide and water vapor (neither of which you can see.) Any smoke you see if simply soot from the burning of the wick. (Looking a little deeper, wax, or paraffin, is a covalently bonded hydrocarbon alkane with the approximate formula C25H52. When it reacts with oxygen in a combustion reaction, the balanced equation for it is: C25H52 + 38O2 --> 25CO2 + 26H2O.)

No, candle wax is not a conductor of electricity. It is an insulator.
A wax candle is an example of something made of wax that can be lit.
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.
Burning 1 mole of candle wax (C25H52) releases about 1,784 kJ of energy. Assuming complete combustion and constant heat output, and using the specific heat capacity of candle wax, it would take approximately 2 hours to burn 1 mole of candle wax at a steady rate.
Tallow is used as candle wax
Candle wax evaporates when the candle is burning because the heat from the flame causes the wax to melt and turn into a gas, which then evaporates into the air.
