Two different answers:Yes, an exothermic reaction releases energy into its surroundings No, its products do NOT have more energy than the reactant(s)
Endothermic. Assuming the energy absorbed is heat. Exothermic reactions release heat, such as the oxidation of hydrogen to create water.
More technically, the energy is released.
A reaction that releases energy is exothermic.
Endothermic means that the net energy produced when chemical bonds reform is less that the energy required to break the original bonds. (It gets cold because it need more energy from the surrounding molecules)Exothermic means that the net energy produced is more than the required energy to break the original bonds. (it gets hot because it releases energy)Using logic and personal experiences, when you ignite something, such as methane, it burns. just the fact that it burns shows that it is releasing energy in the form of light/heat. this makes the combustion of methane Exothermic.

An endothermic reaction contains more chemical energy.
Exothermic. Glucose is one of the major source of energy of the body and can only act as an energy source because its breakdown into CO2 is an exothermic reaction.
Yes, fusion is exothermic until nickel & iron are produced.

exothermic
Condensation is generally exothermic in that the material doing the condensing will be giving up thermal energy to do so. And giving up heat energy is the exit of thermal energy, hence the name exothermic. The atoms or molecules of this consate give up some of their kinetic energy, their energy of atomic or molecular motion, that thermal energy, to condense.
Although it is hard to predict if a reaction will be exothermic or endothermic, there are many factors that can be considered when trying to determine it. first endothermic reactions usually employ the breaking of strong bonds, and the creation of weak bonds. While exothermic reactions usually break weak bonds and create strong bonds. Sadly these are the only ways to predict if a reaction will be endothermic or exothermic, altough there are other methods that could be used that are much more complex.
Single replacement reactions can be either endothermic or exothermic, depending on the specific reaction. The energy change of the reaction will determine whether it is endothermic (absorbs heat) or exothermic (releases heat).
