Endothermic reactions are those which absorb energy in the form of heat from the surroundings. This results in a decrease in the temperature of the surroundings during the reaction.
During an exothermic reaction.
An endothermic reaction is characterized by a net absorption of energy, where energy is taken in from the surroundings. This type of reaction requires heat input to proceed, and the products have higher energy than the reactants.
You probably mean "what reaction releases energy," in which case, lots. Reactions that release energy into the environment are called exothermic reactions. An example of which would be mixing sodium (Na) and water (H2O) to form sodium hydroxide (NaOH), hydride (H2), and heat/energy. 2Na + 2H2O ---> 2NaOH + H2 + heat/energy
Endothermic changes are processes where energy is absorbed by the system from its surroundings. This results in a decrease in temperature in the surroundings during the process. Examples include melting ice and evaporating water.
During an endothermic reaction, energy is absorbed from the surroundings. This energy is often taken from the immediate environment, including your skin, resulting in a cooling sensation. Even though energy is being absorbed overall, it feels like heat is being taken away from your body, making it feel cold.
An endothermic reaction is one in which energy is taken in from the surroundings to drive the reaction. This type of reaction requires an input of energy to proceed. It often results in a decrease in temperature of the surroundings.

A reaction where energy is taken in.
An endothermic reaction is a reaction in which energy is taken in from the surroundings, resulting in a decrease in temperature of the system. This type of reaction requires an input of energy to break bonds in the reactants and form bonds in the products.
Depending on the particular chemical reaction, energy may be either released or absorbed.
During an exothermic reaction.
In an endothermic reaction, heat is taken in from the environment. Heat is a form of energy. Therefore, energy is taken in, i.e. absorbed.
An endothermic reaction is a chemical reaction in which more energy is taken in than given off. This means that energy is absorbed from the surroundings during the reaction, causing a decrease in temperature. An example of an endothermic reaction is the reaction between baking soda and vinegar.
Depending on the particular chemical reaction, energy may be either released or absorbed.
Combustion, burning, releases more heat that is taken in to start the reaction.
An endothermic reaction is characterized by a net absorption of energy, where energy is taken in from the surroundings. This type of reaction requires heat input to proceed, and the products have higher energy than the reactants.
