A voltaic electrochemical cell is constructed using the following reaction. The half-cell components are separated by a salt bridge. Br2(1) + Mn(s)-2Br (aq) + Mn2+(aq) Write the reactions that take place at the anode and at the cathode, the direction in which the electrons migrate in the external circuit, and the direction the anions in the salt bridge migrate. Use smallest possible integer coefficients. If a box is not needed, leave it blank. Enter the reaction that takes place at the anode. Include state symbols: > Enter the reaction that takes place at the cathode. Include state symbols: In the external circuit, electrons migrate v the Mn electrode the Br, electrode. Anions migrate vthe salt bridge the Br2 compartment.

Write the cell notation for an electrochemical cell consisting of an anode where Sn (s) is oxidized to Sn2* (aq) and a cathode where Cu²* (aq) is reduced to Cu (s). Assume all aqueous solutions have a concentration of 1 mol L.

A voltaic cell is constructed in which the anode is a Al|Al3+ half cell and the cathode is a H2|H+ half cell. The half-cell compartments are connected by a salt bridge. (Use the lowest possible coefficients. Be sure to specify states such as (aq) or (s). If a box is not needed, leave it blank.)
