In a future hydrogen-fuel economy, the cheapest sourceof willcertainlybe water. It takes467kJ to produce one mol of H atoms from water. What is the frequency, wavelength and minimum energy of a photon that can free an H atom from water?
carbon- carbon bonds form the “backbone” of nearly every organic and biological molecule. The average bond energy of the C-C bond is 347kJ/mol. Calculate the frequency and wavelength of the least energetic photon that can break an average C-C bond. In what region of the electromagnetic spectrum is this radiation?
Are the bonds in each of the following substances ionic, nonpolar covalent, or polar covalent? Arrange the substances with polar covalent bonds in order of increasing bond polarity:
(a) KCl
(b) P4
(c) BE3
(d)SO2
(e) Br2
(f)NO2
