There are 2; the melting of the candles wax is physical but the wick burning is chemical.
Chemical energy in the match is converted to thermal energy, which produces heat to ignite the candle.
Yes, a combination reaction occurs when two or more reactants combine to form one product. This type of reaction typically involves the synthesis of a compound.
The energy being released from a burning candle is primarily in the form of heat and light. The flame is the result of a chemical reaction between the wax and oxygen, producing energy in the form of heat and light.
A reaction force is a type of contact force that occurs in response to an action force. It acts in the opposite direction to the action force, according to Newton's third law of motion.
A chain reaction is a type of reaction that keeps going on its own once it starts due to the products of the reaction continuing to fuel the reaction. Nuclear fission reactions in nuclear power plants and explosions are examples of chain reactions that continue on their own once initiated.
When water is removed, dehydration is a type of reaction that occurs.
This is a thermal degradation reaction.
A fusion reaction.
maybe i dont care
An exothermic reaction is a reaction where heat or light energy is released. An example of this type of reaction is burning a candle.
A candle burning in air consumes about 4 grams of oxygen for every gram of wax that is burned. This ratio can vary slightly depending on the type of wax in the candle.
Chemical energy in the match is converted to thermal energy, which produces heat to ignite the candle.
This is an endothermic reaction.
Nuclear fission is the primary type of nuclear reaction that occurs in a reactor. It involves the splitting of heavy atomic nuclei to release energy.
Oxidation or combustion
Endothermic reaction
