Explanation / Answer
Which statement about the Born-Haber cycle is false?
d. The cycle involves an enthalpy of fusion.
The answer is d. The Born Haber cycle do not include the enthaply of fusion
Which statement about covalent bonds is false?
d.Covalent bonds are unreactive.
Covalent bonds are reactive. If you give appropriate energy, these bonds break and can form new bonds which is the basis of the formation of the new compounds.
