Question

what are endothermic reaction plz with explanation​

Answer 1

Answer:

An endothermic reaction is a chemical reaction in which more energy is needed to break bonds in the reactants than is released when new bonds form in the products. A constant input of energy, often in the form of heat, is needed to keep an endothermic reaction going.

• Endothermic reactions are chemical reactions in which the reactants absorb heat energy from the surroundings to form products. These reactions lower the temperature of their surrounding area, thereby creating a cooling effect.

$\pink { \tt{</u></em></strong><strong><em><u>EXAMPLE</u></em></strong><strong><em><u>:</u></em></strong><strong><em><u>-</u></em></strong><strong><em><u> }}$When ammonium chloride (NH4Cl) is dissolved in water, an endothermic reaction takes place. The salt dissociates into ammonium (NH4+) and chloride (Cl–) ions. The chemical equation can be written as follows: NH4Cl (s) + H2O (l) ⟶ NH4Cl (aq) – Heat.
