Explanation:
PLS PLS mark it as BRAINLIEST..
Exothermic reactions are reactions that release energy into the environment in the form of heat. Exothermic reactions feel warm or hot or may even be explosive.
More energy is released making chemical bonds than is used breaking them. In an exothermic reaction, the enthalpy change has a negative value: ΔH < 0 ion
example :-any combustion reaction
-a neutralization reaction
-rusting of iron (rust steel wool with vinegar)
-the thermite reaction
-reaction between water and calcium chloride
-reaction between sodium sulfite and bleach (dilute sodium hypochlorite)
-reaction between potassium permanganate and glycerol
-reaction between sodium and chlorine to make sodium chloride (table salt)
-reaction between water and any strong acid
-reaction between water and any anhydrous salt
