WebAnswer: When chemical reactions occur, they are accompanied by a transfer of energy, sometimes to and sometimes from the surroundings, which can often take place in the form of a temperature change. An endothermic reaction is one that results in the absorption of heat, and an exothermic one is th...

Why are endothermic reactions useful? – KnowledgeBurrow.com
WebExergonic reactions are also called spontaneous reactions, because they can occur without the addition of energy. Reactions with a positive ∆ G (∆ G > 0), on the other hand, require an input of energy and are called … WebA strongly exothermic reaction will usually also be exergonic because ΔH⚬ makes a major contribution to ΔG⚬. Most of the spectacular chemical reactions that are demonstrated in classrooms are exothermic and exergonic. The opposite is an endothermic reaction, which usually takes up heat and is driven by an entropy increase in the system. can i withdraw from my ira and put it back
