There are two types of reaction in reference to heat change.viz: Endothemic nd exothemic reaction.Endothemic reactions are reactions dat involves the absorbtion of heat while exothemic reactions involve d giving out of heat.

Endothermic reaction absorbs heat while exothermic reaction gives out heat

An endothermic reaction is one in which heat is absorbed from the surroundings into the system, meaning that the surroundings lose heat and the temperature around the reaction decreases.

The answer is ENDOTHERMIC cos endothermic deals with the absorbtion of heat while the other one which is exothermic deals with the release of heat

An endothermic reaction has a positive change in hydrogen vale indicating that heat energy has been absorbed from the surroundings.

Endothermic Reaction is one in which heat is absorbed from the surronding during the reaction.
Therefore,when a reaction is said to absorb heat from its surrounding;it is said to be an Endothermic Reaction while when it is said to give-off or release heat to the surrounding;it is said to be an Exothermic Reaction.

When heat is absorbed it is called endothermic reaction and when it is liberated it is called exothermic

This is elementary chemistry. Endothermic reactions releases heat while endothermic reactions are reaction where heat is absorbed

Endothermic reaction is a reaction in which an absorption of heat from the surrounding takes place in passing from reactants to products. In summary, heat is absorbed from the surrounding.

the answer is endothermic reaction because heat is absorbed from the environment unlike exothermic reaction where by heat is evoled or lost to the enviroment.e.gsodium react with cold water rapidly to liberate heat to it surrounding hence it is an exothermic reaction.

When heat is absorbed during a chemical reaction, it's called an endothermic reaction because the system (the reacting substances) takes in energy from the surroundings, usually in the form of heat. This energy is required to break chemical bonds in the reactants so that new bonds can form in the products.

As a result, the temperature of the surroundings may drop, because heat is being drawn into the reaction. Common examples of endothermic reactions include photosynthesis and the reaction between barium hydroxide and ammonium chloride.

In short:
Endothermic = energy in (heat absorbed).
