Worksheet Endothermic And Exothermic Reactions

Worksheet Endothermic And Exothermic Reactions During chemical reactions the bonds between atoms break and new bonds form Energy must be absorbed to break a bond so breaking bonds is endothermic Making new bonds is exothermic because energy is released a When green copper carbonate decomposes the equation is CuCO 3 CuO CO 2 copper carbonate copper oxide carbon dioxide

Chemical processes are labeled as exothermic or endothermic based on whether they give off or absorb energy respectively 7 3 Exothermic and Endothermic Reactions is shared under a CC BY NC SA 3 0 license and was authored remixed and or curated by LibreTexts Atoms are held together by a certain amount of energy called bond energy In Sam s case when ammonium nitrate was dissolved in water the system absorbed heat from the surrounding the flask and thus the flask felt cold This is an example of an endothermic reaction In Julie s case when calcium chloride was dissolved in water the system released heat into the surroundings the flask and thus the flask felt hot This is an example of an exothermic reacti
