Q2: Consider a molecular interaction denoted as X-HY, where "-" signifies a covalent bond and "..." indicates hydrogen bonding. The system can be described as a superposition of three structures: |X-HY-)= V1+s 1 0 (s) |X:, H+,: Y-) = (1); |X:-, H-Y) = 0 0 0 (s), 1 where 0 < s << 1. The first (last) structure represents a pure covalent bond between the atoms X (Y) and H, with Y (X) carrying a negative charge. The middle structure depicts an ionic configuration where X and Y bear negative charges, while H carries a positive charge. In this structure, there is no covalent bond.

Calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. Round your answer to 3 significant digits. Also, be sure your answer contains a unit symbol. Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such as silver or gold. In essence the metal object is made the cathode of an electrolytic cell in which the precious metal cations are dissolved in aqueous solution. Explanation W Lectu # 3 Check E 54 0.0 X R…
