For the E0E_0E0 potential step, =[(+ik)/(ik)]A.\beta = [(\alpha + ik)/(\alpha - ik)]A.=[(+ik)/(ik)]A. This is because hydrogen chloride has almost twice the molecular weight of ammonia, and the rate of diffusion is inversely proportional to the square root of the molecular mass of the gas. Concentrated solutions of this acid are extremely corrosive. 15. To form a Cu2+ ion a copper atom loses the 4s electron and one of the 3d electrons, leaving it with the electronic structure: 1s2 2s2 2p6 3s2 3p6 3d9. 16.
