How do you know that the burning of candle of wax is an exothermic change?

∙ 8y ago
An exothermic reaction involves the release of heat into a system. The burning of a candle is combustion reaction. Combustion reaction release heat, and this can be detected and measured by the burning of a candle's wax. From these testable observations it is determined fact that candle burning is indeed exothermic.

How do you know that a burning of candle wax is an exothermic change?
Because heat is coming out of the reaction, that means it is losing energy
How we know a chemical change has occurred when burning a candle?
Burning is a chemical reaction, an oxydation.
How do you know if a candle is a chemical change?
Can you reverse the change?
Is Burning of a dead body is endothermic or exothermic?
the answer is exothermic, because of the fact that anything that puts off heat or burns is exothermic.
What happens when you cover the top of a glass that has a burning candle inside?
i dont know just tell me the answer
Why cant you get candle material back after burning?
Candle while burning, its wax gets burnt and matter gets changed into heat and light energy. These get radiated and pass away. So we cannot get back the candle material. Energy can neither be created nor be distroyed. This cannot be violated in any case. But matter can be changed into energy. So to get back the matter we have to know the technique to collect heat and light energy and know the skill to change it back to matter.
How do you know that burning coal is exothermic?
It release heat which you feel as it being hot. Exothermic means to release heat and endothermic means to intake heat(energy) making it feel cold like water freezing.
How do you know if an enthalpy change diagram is endothermic or exothermic?
If you plot the reaction coordinate (what I think you mean by "enthalpy change diagram"), the reaction will be exothermic if the products are lower on the graph than the reactants. If they are higher than it is endothermic. For instance, if you go to the linked Wikipedia page (link to the left of this answer), the graph shown is of an exothermic reaction.
Sulfuric acid and magnesium ribbon endothermic or exothermic?
I don't know for sure, but it is probably exothermic. (PLEASE CORRECT ME!)
Which animal groups are endothermic?
all animals are exothermic. If you change this answer, then you don't know what that word means. All living creatures are exothermic, meaning they give off heat. Even "cold blooded" animals give off heat.
Is ammonium endo or exothermic?
endothermic but don't know why? As AN crystals are formed the reaction is exothermic. Endothermic when it melts back with water. This is the reason AN is used in cold packs.
What is lightning a candle a physical or chemical change?
