What is an Exothermic Reaction? A reaction that is chemical in nature and is characterized by the release of energy in the form of heat or light is called an exothermic reaction. Matching a light using a matchstick is one example of this type of reaction where the release is in the form of both heat and light.An exothermic reaction is a reaction in which energy is released in the form of light or heat. Thus in an exothermic reaction, energy is transferred into the surroundings rather than taking energy from the surroundings as in an endothermic reaction.Solution : 1) Reactions in which heat energy is released by the reactants is called an exothermic reaction. Eg : Burning of coal. <br> 2) when coal burnt in oxygen, carbon dioxide is produced an also large amount of heat enery is also released. <br> `C+O_(2)rarr CO_(2)+Q` <br> 3) It is an exothermic reaction.

Which is an exothermic reaction?
In thermochemistry, an exothermic reaction is a “reaction for which the overall standard enthalpy change ΔH⚬ is negative.” Exothermic reactions usually release heat and entail the replacement of weak bonds with stronger ones.

What is exothermic and endothermic reaction Class 10?
CaO(s) + H 2 O(l) → Ca(OH) 2 (aq) + Heat. Since heat is produced / released in this reaction, this reaction is called an exothermic reaction. A chemical reaction in which a large amount of heat / energy is absorbed is called endothermic reaction. For example, On heating of Calcium Carbonate (limestone)

What is an example of an exothermic reaction in everyday life?
Burning Of Candles
The burning of the candle is an exothermic reaction. The candle is a paraffin wax which is made up of hydrocarbons. When the candle burns, it comes in the contact of oxygen, and there is a breaking of hydrocarbon bonds and hence the release of energy take place.
Why is it called an exothermic reaction?
Chemical reactions that release energy are called exothermic. In exothermic reactions, more energy is released when the bonds are formed in the products than is used to break the bonds in the reactants. Exothermic reactions are accompanied by an increase in temperature of the reaction mixture.
