(C) The wavelengths of absorbed radiation for these compounds are 770 nm and 290 nm (not respectively). Match the complex ion to the wavelength of radiation and explain.

4. A balloon is becoming its full extent after heating the air inside. In the final stage of this process the volume of the balloon changes from 4.0 × 106 L to 4.5 × 106 L by addition of 1.3 × 108 J of the energy as heat. Assuming the balloon expand against a constant pressure of 1.0 atm, please calculate E for the process.
