Is wax burning exothermic?
Explanation: If we talk about melting of wax then it is endothermic but if we talk about burning of candle then it is exothermic.
When candle is burning is it endothermic or exothermic?
A burning candle is an example of an exothermic reaction.
What is the reaction when candle wax is burning?
oxygen
All the light a candle makes comes from a chemical reaction known as combustion in which the wax (made from carbon-based chemicals typically derived from petroleum) reacts with oxygen in the air to make a colorless gas called carbon dioxide. Water is also produced in the form of steam.
What type of reaction occurs when a candle is burned exothermic?
A candle flame is an exothermic reaction because when the candle burns it gives off heat rather than taking it in which would be endothermic. When Endothermic reactions absorb energy , a temperature drop is measured during the reaction.
Which of the following is an example of an exothermic process a candle burning?
Another simple example of an exothermic reaction is combustion, such as lighting a candle. An initial input of energy causes oxygen and wax react to produce carbon dioxide, water, and heat.
Is it exothermic or endothermic?
An exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings.”
Does burning a candle create co2?
After all, candles emit carbon dioxide too. Most candles are made of paraffin, a heavy hydrocarbon derived from crude oil. Burning a paraffin candle for one hour will release about 10 grams of carbon dioxide.
What chemical is in candle wax?
Paraffin wax
Paraffin wax (or petroleum wax) is a soft colorless solid derived from petroleum, coal or oil shale that consists of a mixture of hydrocarbon molecules containing between twenty and forty carbon atoms….Paraffin wax.

Is the burning of candle is a thermochemical reaction?
When the solid burns, the hydrocarbon reacts with oxygen to form carbon dioxide and water. The reaction is exothermic, meaning it releases heat to the atmosphere along with the other products.
How is burning a match an exothermic reaction?
A match requires initial energy, provided by the heat generated from the friction as it strikes the rough surface on the matchbox to ignite it. Once the match starts burning, it releases more energy than was required for ignition so the reaction is still exothermic.
How could you detect an exothermic reaction?
There are two methods for distinguishing between exothermic and endothermic reactions.
- Monitor temperature change. When energy is released in an exothermic reaction, the temperature of the reaction mixture increases.
- Calculate the enthalpy of reaction (ΔH)
