The enthalpy of formation of xef2(g) is –108 kj mol–1 and the bond dissociation enthalpy of the f–f bond is 155 kj mol–1 . what is the average bond dissociation enthalpy of a xe–f bond

Average bond dissociation enthalpy of a (Xe–F) bond is 131.5kJ/mol.

Expatiation:

..(1)

..(2)

Subtracting (1) from (2)

Average bond dissociation enthalpy of a (Xe–F) bond :

Since there are two (Xe-F) bonds in molecule the average the bond energy of Xe-f bond will be =

Hence, Average bond dissociation enthalpy of a (Xe–F) bond is 131.5kJ/mol

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
