Explanation:
A quick difference between endothermic and exothermic involves reactions in the environment. An endothermic reaction takes place when energy is absorbed from surroundings in the form of heat, and exothermic is when energy is released from the system into the surroundings. Both terms are mostly used in science and chemisThe reaction occurs when two or more molecules interact with each other, and something happens or is produced. Endothermic absorbs heat, and exothermic produces heat. The difference between the words themselves and the prefixes give another hint as to their differences. Thermic refers to heat, endo means inside, and exo means outside. Endothermic, heat absorbed or in something, exothermic, heat being released or sent out.
1.Endothermic must be supplied with heat and is basically the opposite of exothermic. An everyday reaction is in the cooking of an egg. There must be heat added or absorbed from the environment to cook the egg or any other food item. The two reaction differ because the amount of energy of the reactants is fewer than the products, as opposed to an exothermic reaction.try, but there are everyday examples as well.
Exothermic reactions, on the other hand, make the surrounding environment hotter since heat energy is released, radiating energy while it progresses. A campfire is an excellent example of this reaction. The energy from the chemical bonds of paper and wood is released in the form of light, and of course, heat. Those sitting around the campfire become warm as a result of the released heat.
2.Exothermic reactions will contain less energy because it is removed from the chemical bonds in the reactants. Activation energy, like the match for the campfire, is needed to get the process started. Following the process, the product will have lower heat and is more compact.
Answer:1 and 2 will be endothermic while 3 and 4 will be exothermic
Explanation:
Displacement reactions are always exothermic while dissolution of salts may be endo or exo. In this case it is endothermic.
