Mg and hcl reaction endo or exothermic
WebbReactions in which heat is released along with the formation of products are called exothermic reactions. Example of exothermic reaction: Burning of natural gas: CH 4 (g) + 2O 2 (g) CO 2 (g) + 2H 2 O (g) + Heat. Reactions in which energy is absorbed are known as endothermic reactions.
