An endothermic reaction is a reaction which requires energy. The enegry is required for the reaction to take place, maning the energy is used up in the reaction. An example of an endothermic reaction is photosythesis.

∙ 9y agoEnergy is conserved in an endothermic reaction because the heat absorbed becomes potential energy. This potential energy isn't lost energy, it's simply stored, instead of being used.

What is the difference between an exothermic and endothermic reaction?
Exothermic (hyperthermic) reaction: a chemical reaction that releases energy,*Endothermic (hypothermic) reaction: a chemical reaction that absorbs energy.** Energy = heat, light, etc.The direction of Heat transfer:Exothermic reactions transfer heat energy to the environment.Endothermic reactions transfer heat energy from the environment .
What is given off in all energy changes?
energy is released which makes it hotter because it is an exothermic reaction, or energy is absorbed which makes it colder and an endothermic reaction =]
What is an example of an endothermic chemical change?
An endothermic reaction is one that requires energy to take place (e.g. light or heat energy); breaking bonds in a molecule is always endothermic; and energy is a reactant.Some examples of endothermic reactions are as follows:citric acid and sodium bicarbonate.ammonium chloride and watera chemical cold pack used in first aid kitsphotosynthesisbioluminescence by a firefly
What is striking a match an example of?
Striking a match is an example of an endothermic reaction. It is also an example of simple combustion and a chemical reaction.
The change in which ice absorbs energy and melts is a?
Endothermic reactions are those in which energy is absorbed during the reaction. Exothermic reactions are those in which heat is evolved during the reactions.When ice melts its absorbs energy in the form of heat so why it melts,
A chemical reaction that requires a net input of energy?
"Activation Energy reactions"; Endothermic reactions require energy.
Does the energy go from surrounding to the chemicals in an exothermic reaction?
No. It is endothermic when this happens.
A chemical reaction that absorbs free energy?
Can be called endothermic.
What is the different between endothermic and endothermic?
The difference between endothermic and exothermic energy is that exothermic energy is the reaction that releases energy and endothermic is the reaction in ehich energy is absorbed.
What is a reaction which takes in energy?
endothermic
Reaction that absorbs energy in the form of heat?
Endothermic.
An endothermic reaction is one that uses which form of energy?
An endothermic reaction is one that uses chemical energy.
What chemical reaction describes where energy is absorbed?
Endothermic, if the energy is in the form of heat.
How do chemical reactions that absorbs energy are called?
Endothermic reaction = absorbs energyExothermic reaction = releases energy
A reaction that absorbs energy is called?
Endothermic-take in Heat, as opposed to exothermic which gives off heat-like a fire or explosion.
What happens in an endothermic reaction?
An endothermic reaction need heat to occur.
A reaction in which energy is absorbed?
endothermic reaction
