Consider the following information. the lattice energy of cscl is δ h lattice = − 657 kj/mol. the enthalpy of sublimation of cs is δ h sub = 76.5 kj/mol. the first ionization energy of cs is ie 1 = 376 kj/mol. the electron affinity of cl is δ h ea = − 349 kj/mol. the bond energy of cl 2 is be = 243 kj/mol. determine the enthalpy of formation, δ h f , for cscl ( s ) .

-310.5 kJ/mol

Explanation:

The CsCl(s) will be formed by steps:

The enthanlpy of formation is the sum of all the energies involved in the steps:

ΔHf = 76.5 + 376 -349 + 243 -657

ΔHf = -310.5 kJ/mol

kuchisake

kuchisake-onna (口裂け女, "slit mouth woman ") is a malevolent figure appearing in japanese ghost stories, possibly dating back to the edo period. she takes the form of a masked woman who approaches people and asks them if they believe she is pretty.
