The wick. The wax is there to prevent the wick from burning too fast.
the flame of a candle is a reaction of oxygen with carbon to form carbon(iv)oxide and vapour
It is actually both. The burning of the wick involves a chemical change. The physical change is the wax.
the products of a burning candle are water vapor and carbon dioxide
No, burning a candle is not reversible. When a candle is burned, the wax is melted and the wick is consumed, resulting in irreversible changes to the candle's structure.
A burning candle produces thermal energy and light.
a burning candle is a light source due to the fire.
A burning candle produces water vapor and carbon dioxide gas.
Burning a candle is the process in which the wick is burnt. The wax is there to make the wick burn slower in order to let the candle burn for longer. Melting wax is part of the process but not burning the candle itself.
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.
combustion is burning -_-
Burning the Candle - 1917 was released on: USA: 5 March 1917
Vapours of the candle wax, which contain carbon and hydrogen, react with oxygen in the air to create carbon dioxide and water. Often, the combustion is incomplete and small amounts of carbon monoxide as well as carbon (soot) are released.
