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 else can I help you with?
Is thermal decomposition a endothermic or exothermic reaction?
Thedecompositionof water is endothermic since energy is required to break up the bonds between the hydrogen and oxygen in the water molecule. Therefore the decomposition of water absorbs energy, making the reaction an endothermic one.
What is the difference between energy releasing reaction and energy absorbing action?
Beacuse when you release energy out of your body or somthing, somthing has to take in the energy so absorbing;SO, it's like a chain reaction you release somthing els takes in, like humans breath oxygen plants breath our carbon dioxide and plants give us oxygenSo, it differs because when energy-realses somthing needs to take that energy in as in absorbing
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 the difference between a allergy cold and a regular cold?
One is caused by an allergic reaction, one is caused by a virus
What type of energy do people get from the food they eat?
we get chemical energy from food.but they are expressed in calories.two persons misread the questions i think.ok,see about the chemical energy. The energy held in the covalent bonds between atoms in a molecule is called chemical energy. Every bond has a certain amount of energy. To break the bond requires energy -- in chemical language it is called endothermic. These broken bonds then join together to create new molecules, and in the process release heat -- chemists call this exothermic. If the total heat given out is more than the heat taken in then the whole reaction is called exothermic, and the chemicals get hot. The burning of methane in oxygen is an example of this. If the heat taken in is more than the heat given out then the whole reaction is endothermic and the chemicals get cold. Combining carbon and hydrogen to make methane is an example. We rarely meet such reactions in every day life. They happen in living cells, the energy being supplied by sunlight or some other source. ATP is the molecule used by life to carry chemical energy. The bond between two of its phosphate groups carries a lot of energy because both phosphates have negative electric charge.
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.
How can you tell the difference between an endothermic and exothermic reaction?
You can generally tell by changes in temperature, whether you have an exothermic reaction which produces heat, or an endothermic reaction which consumes heat.
What is the difference between a exothermic chemical reaction and a endothermic chemical reaction?
energy released by the reaction or energy absorbed.
Is the reaction between HF and NaOH an endothermic or exothermic reaction?
EXTREMELY!!!!! exothermic. As in fires and explosions exothermic.
What is the difference between endothermic and exothermic?
An endothermic reaction absorbs heat. It cannot proceed without the addition of heat. An exothermic reaction releases heat. Since heat causes chemical reactions to go faster, an exothermic reaction can "feed on itself" and get out of control, releasing damaging amounts of heat and, if proceeding in a closed container, causing an explosion.
What is the difference between endothermicand and exothermic reaction?
An endothermic reaction absorbs energy, making its environment cooler. Ab exothermic reaction releases energy, making its environment warmer.
What is the difference between endothemic and exothemic?
The terms "endothermic" and "exothermic" refer to whether a chemical reaction absorbs or releases heat, respectively. In an endothermic reaction, heat is absorbed from the surroundings, while in an exothermic reaction, heat is released into the surroundings.
Is the reaction between zinc and copper sulphate endothermic or exothermic?
The reaction between zinc and copper sulfate is exothermic, as heat is released during the reaction.
What is the difference between an exothermic and an endothermic chemical reaction?
In an exothermic reaction, energy is released in the form of heat, making the surroundings warmer. In contrast, an endothermic reaction requires energy input from the surroundings to proceed, making the surroundings cooler as it absorbs heat.
Is the reaction between potassium permanganate and glycerin a endothermic or exothermic reaction?
The reaction between potassium permanganate and glycerin is exothermic, which means it releases heat as it proceeds. This reaction is highly exothermic and can lead to spontaneous combustion in some cases.
What is one similarity between exothermic reaction and an endothermic reaction?
Endothermic reactions and exothermic reactions all involve something called an enthalpy change: a change in the amount of energy a chemical contains. The difference here is that exothermic reactions release heat energy to their surroundings, whereas endothermic reactions absorb heat from their surroundings (in effect, getting colder).
What is the difference between a endothermic reaction and a exothermic reaction?
In an endothermic reaction, energy is absorbed from the surroundings, resulting in a decrease in temperature. In an exothermic reaction, energy is released to the surroundings, leading to an increase in temperature.
