When a candle burns, it releases heat and light energy into the surrounding environment. This release of energy is a characteristic of exothermic reactions, where energy is given off to the surroundings. In the case of candle wax burning, the chemical bonds in the wax molecules are broken, releasing energy in the form of heat and light, confirming that the process is indeed exothermic.

How we know a chemical change has occurred when burning a candle?
Burning is a chemical reaction, an oxydation.
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.

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.
Why does burning of candle produce flames and burning of coal cannot?
First of all we will have to know that what is a flame made up of,a flame is made at a point where fuel and oxygen combine,so in case of both candle and coal there is a fuel ie.wax in candle and coal is itself a fuel.................but if we just think till this much then even coal should produce flame but it doesn't go like this ,actually we are missing something ie. hydrogen(the main component in every flame producing substance).........if hydrogen is not there flame will not be produced .So wax has hydrogen atoms whereas coal doesn't because coal has been burnt before and hydrogen has been used.................that is why hydrogen containing waxy candle produces flames whereas already burnt coal just gives heat not flames. Hope this helps.
How do you know that the burning of candle of wax is an exothermic change?
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 if a candle is a chemical change?
Can you reverse the change?
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.
What is the energy change in burning ethanol?
if you were smart u would know that u just have to write TINECIBE. it meens there is no enargy change in it. it stays the same.
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?
When you cover the top of a glass with a burning candle inside, you restrict the flow of oxygen to the flame. This causes the flame to consume the available oxygen within the glass, leading to the extinguishing of the flame due to lack of oxygen. Additionally, the heat and gases produced by the burning candle may build up within the glass.
How do you know that burning coal is exothermic?
Burning coal is exothermic because it releases heat energy in the form of light and heat during the combustion process. This is a result of the chemical reaction between the coal (carbon) and oxygen in the air, which produces carbon dioxide and water vapor along with heat. The net result is that energy is released in the form of heat, making it an exothermic reaction.

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.
Why does the wax not freeze at the top of a candle?
wax do not freeze on top of the candle because the heat on top of the candle makes it melt and as we know heat makes solid melt.
