Answer:
Exothermic Reactions.
Explanation:
Reactions that release energy are called exothermic reactions.
Whereas that absorb energy are called Endothermic reactions.
More energy is being released to the surroundings than was absorbed to initiate and maintain the reaction in case of exothermic reactions.
Burning of a candle is an exothermic reaction.
The most common way of preventing bumping is by adding one or two boiling chips to the reaction vessel. However, these alone may not prevent bumping and for this reason it is advisable to boil liquids in a boiling tube, a boiling flask, or an Erlenmeyer flask.
