I want to thank your team (Jeff) for finding a new writer when you were unable to reach my existing writer to revise my paper. I appreciate your professionalism and efforts. Thanks
Endothermic means absorbs heat. Exothermic means releases heat.
Think of it this way.
##”EX”##othermic means ##”EX”##it. If the heat is ##”EX”##iting, then it is an ##”EX”##othermic reaction.
This means that the system goes to a lower energy level.
The burning of hydrogen gas is an exothermic reaction.
##”2H”_2(“g”) +” O”_2(“g”) → “2H”_2″O”(“g”) + “heat”##
##”EN”##dothermic means ##”EN”##ter. If the heat is ##”EN”##tering, then it is an ##”EN”##dothermic reaction.
This means that the system goes to a higher energy level.
The decomposition of calcium carbonate into calcium oxide and carbon dioxide is an endothermic reaction.
##”CaCO”_3(“s”) + “heat” → “CaO”(“s”) + “CO”_2″(g”)##
The following video shows some more exothermic and endothermic processes.
