Question

what are exothermic and endothermic reaction give suitable examples

Answer 1

Exothermic Reaction: A chemical reaction in which heat is given out is known as exothermic reaction.

Endothermic Reaction: A chemical reaction in which heat energy is absorbed is known as endothermic reaction.

examples:

example of an exothermic reaction is combustion, such as lighting a candle. An initial input of energy causes oxygen and wax react to produce carbon dioxide, water, and heat.

ndothermic or heat-absorbing processes: melting ice cubes. ... converting frost to water vapor (melting, boiling, and evaporation, in general, are endothermic processes) making an anhydrous salt from a hydrate.

PLS MARK AS BRAINLIEST!!!

Answer 2

an exothermic reaction is that which gives off energy to the surroundings eg a fire giving off heat
an endothermic reaction takes in energy from the surroundings eg snowman melting hope it helps you
