A chemist wants to make 4.5L of a 0.340M CaCl2 solution.What mass of CaCl2 (in g ) should the chemist use?
How many unpaired electrons in the F22+ ion are based on molecular orbital theory? The order of the molecular orbitals are (σ2s)(σ*2s)(σ2p)(π2p)(π*2p)(σ*2p).
Free radicals are also important in many environmentally significant reactions. For example, photochemical smog, which forms as a result of the action of sunlight on air pollutants, is formed in part by the following two steps.
