An exothermic reaction is a chemical reaction that releases energy in the form of light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants → products + energy ==Overview== An exothermic reaction is a chemical or physical reaction that releases heat. It gives out energy to its surroundings. The ene...
Chemical reaction giving off heat in the process, such as combustion.
A chemical reaction in which energy is released as heat and light. The opposite of an endothermic reaction in which energy is absorbed.
(from the article `alkali metal`) The reaction with water of liquid sodium having a high surface area can be explosive. The sodium-water reaction is highly exothermic (that is, heat ... The alkali metals can be burned in atmospheres of the various halogens to form the corresponding halides. The reactions are highly exothermic, ... Ch...
The majority of chemical reactions are accompanied by the evolution of heat - these is known as exothermic reactions. The reaction between an acid and a base is exothermic, it is possible to feel the temperature change when one is added to the other - seegives out more energy than was put in to start the reaction. It has a negative DH. It keeps going after it is started. An example is a fire.
A chemical reaction which evolves heat. Combustion reactions are exothermic
A chemical reaction that proceeds with the liberation of heat.The majority of chemical reactions are accompanied by the evolution of heat - these is known as exothermic reactions. The reaction between an acid and a base is exothermic, it is possible to feel the temperature change when one is added to the other - see below:
A reaction from which heat is lost eg: combustion
In chemistry, exothermic reaction is a chemical change in which heat is liberated.
A reaction from which heat is lost eg: combustion.
[n] - a chemical reaction accompanied by the evolution of heat
Chemical reactions involving the liberation of heat. See Endothermic Reaction. 
A chemical reaction in which heat is evolved.
noun a chemical reaction accompanied by the evolution of heat
Chemical reaction during which heat is given out (see energy of reaction). For example, burning sulphur in air to give sulphur dioxide is an exothermic reaction. 2S + O2 ® SO2
