What is the relationship between bond length and bond strength?
The shorter the bond the stronger it is!!! What is the relationship between bond length and bond strength?
Define endothermic! And explain the difference between endothemric and exothermic!!!
Endothermic is used to describe a chemical reaction when you have to put more energy in to break the bonds then you get out when new bonds form!!!! Endothermic- you put more energy in Exothermic- you get more energy out Define endothermic! And explain the difference between endothemric and exothermic!!!
