How do nonmetals form bonds a. they lose electrons b. they transfer electrons c. they gain electrons d. they share electrons

D) They share electrons

Explanation: Nonmetals under goes a bond called covalent bond. The chemical bond that requires the sharing of electron pairs is known as covalent bond. This bond is of three types namely; polar covalent, non polar covalent, and coordinate covalent.

It's is very difficult for an electron to be removed from nonmetals, that is, they exhibit high ionization energy.

So because of this characteristics, when two nonmetals bond, they share electrons instead of transferring electron.

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
