A crab has an exoskeleton. The combusting wax in a candle wick is exothermic. What does the prefix “exo” mean and how does it apply to the burning of wax?

What is the definition of 'exothermic'?
A chemical reaction that gives off heat ... like burning a candle.
Is melting of candle an exothermic or endothermic reaction?
It is exothermic. When you put your hand close to the burning candle, does the air feel cooler or warmer? If it feels cooler, then it is drawing in heat and is endothermic (endo = in). If it feels warmer, then it is giving off heat and is exothermic (exo = out). (If the system is gaining energy (heat) than it is endothermic, releasing energy is exothermic.)
Is a candle a endothermic or exothermic change?
exothermic- because exothermic gives off heat and endothermic is cold
What is burning candle it is physically Chang or chamically?
Burning a candle is a chemical change, as is burning anything.
What is the effect of candle wax?
Candle wax is the fuel a candle uses to keep burning. So, I guess the effect of the wax is the candle keeps burning.
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.
Is wax in a candle burning an exothermic process or endothermic?
Exothermic process
Is a burning candle exothermic reaction?
Yes, a burning candle is an example of an exothermic reaction. When the candle wax reacts with the oxygen in the air, it produces heat and light energy as byproducts. This release of heat is what makes the candle flame feel warm to the touch.
Why is burning of candle a exothermic reaction?
Because exothermic change releases energy.
Why burning a candle is an exothermic reaction not endothermic?
The reaction releases heat and light to its surroundings, so it is exothermic.
Reaction such as a candle burning give off energy in the form of heat they're called?
Exothermic Trishi! =)
A reaction that releases energy in the form of heat?
It is called an exothermic reaction. Example: a burning candle

What are the changes that are exothermic?
exothermic chemical reaction is any reaction that releases energy to the enviorementex: burning a candle (heat energy is released) eutralization reaction
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
Is exothermic reaction an example of photosynthesis?
An exothermic reaction is a reaction where heat or light energy is released. An example of this type of reaction is burning a candle.
