What are the characteristics of an exothermic reaction?

Answer 1

Exothermic reactions release energy, it often produces an increase in temperature, and in this reaction, the bonds energies of the reactants are less then the energies of the products (meaning it is greater when it is on the reactant side).

Answer 2

In an endothermic chemical reaction, energy or heat is absorbed. Over the course of an endothermic reaction, the reacting system takes energy from its surroundings to produce a reaction. The products of an endothermic reaction have more heat than the reactants.Some examples of endothermic chemical reactions include ice cubes melting into liquid water, liquid water evaporating and becoming water vapor, and a cake baking in an oven. Water's states of matter are the clearest way to compare exothermic and endothermic reactions. As water moves from a solid to a liquid or from a liquid to a gas, the process is endothermic; when water condenses from a gas to a liquid or when liquid water freezes, the reaction is exothermic.Think about the example of ice cubes sitting in a glass of water. The ice and the liquid water are constantly exchanging molecules, meaning some water molecules are freezing while some ice molecules are melting. Assuming the reaction is occurring at room temperature, the rate of melting exceeds the rate of freezing. The ice will eventually melt which means that the net reaction was endothermic, but the reaction involved both absorption and release of energy.

Answer 3

An exothermic reaction releases energy in the form of heat to the surroundings. This type of reaction typically feels warm to the touch and has a negative enthalpy change. Examples include combustion reactions and neutralization reactions.

Answer 4

Heat, light, energy are emitted.. meaning "exo" what is leaving the reaction. :)

Answer 5

Any chemical reaction that releases energy.

such as burning gasoline, living

Answer 6

well one hits another and one absorbs an one dont enit

Answer 7

Endothermic:

-absorbs heat

-feels cold

Exothermic:

-releases heat

-feels hot
