Chemical reactions that release energy in the form of heat, light, or sound are called exothermic reactions.
Example: Mixture of sodium and chlorine to yield table salt
In other words, combination reactions are exothermic.
Reactions that absorb energy or require energy in order to proceed are called endothermic reactions.
For example: In the process of photosynthesis, plants use the energy from the sun to convert carbon dioxide and water to glucose and oxygen.
To put it simply, an exothermic reaction is a chemical reaction in which energy is released in the form or light or heat. If the reactant (A) has more energy than the products (B and C) of a chemical reaction, then the excess energy will released and you have an exothermic reaction. When you digest food, energy is released for your body to use. Combustion reactions (fire) and the explosions of bombs are also good examples of exothermic reactions.
So:
If A ≠B + C, then
A = B + C + Excess Energy
Endothermic reactions, on the other hand, absorb heat. You can notice this when ice melts and when ammonium nitrate is dissolved in water (which is used to create commercial cold/ice packs).
An exothermic reaction is a reaction that gives off heat. For instance, when wood burns heat that was stored in chemical bonds is given off into the environment.
.
An endothermic reaction is a reaction that stores heat. For example, reacting citric acid and baking soda.
.
The above examples are chemical reactions. There are also endothermic and exothermic physical reactions. For instance, boiling water or melting ice cubes is and endothermic reaction because it takes heat to do it, and that heat is stored. Also, dissolving salts can be both endothermic and exothermic (depending on the salt used.)

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 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 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.
How do you predict if a reaction will be exothermic or endothermic?
You can predict if a reaction will be exothermic or endothermic by comparing the energy of the products and reactants. If the products have lower energy than the reactants, the reaction will be exothermic (energy released). Conversely, if the products have higher energy than the reactants, the reaction will be endothermic (energy absorbed).
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.

EXTREMELY!!!!! exothermic. As in fires and explosions exothermic.
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.
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).
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.
Difference between endothermic and exothermic?
Endo draws heat from around it. Exo gives off heat. Example: Ice melting is a endothermic reaction. A match lighting is an exothermic reaction.An exothermic reaction releases heat to it's surroundings. The change in energy is negative. An example is combustion of natural gas.An endothermic reaction absorbs heat, so the temperature of the surroundings drops. The energy is positive. An example is melting ice cubes.
What is the difference between endothermic and exothermic change?
Endothermic reactions absorb heat from the reactants, i.e , the vessel or beaker in which the reactions have happened will be cool to touch........ Whereas in exothermic reactions, Heat will be given out and the vessel will be hot to touch..........
How do you predict if a reaction will be exothermic or endothermic?
You can predict if a reaction will be exothermic or endothermic by comparing the energy of the products and reactants. If the products have lower energy than the reactants, the reaction will be exothermic (energy released). Conversely, if the products have higher energy than the reactants, the reaction will be endothermic (energy absorbed).
