A voltaic cell is constructed with a Ag/Ag+ half-cell and a Cd/Cd2+ half-cell. The silver electrode is positive. Write balanced half-reactions and the overall reaction. Draw a diagram of the cell, labelling the electrodes with their charges and showing the direction of electron flow in the circuit and of cation and anion flow in the salt bridge.
Construct a simulated 1H NMR spectrum, including proton integrations, for CH3CHCl2. Drag the appropriate splitting patterns to the approximate chemical shift positions; place the integration values in the small bins above the associated chemical s..
