Suppose that a fully charged lead¨Cacid battery contains 1.16 L of 5.00 M H2SO4. What will be the concentration of HSO4- in the battery after 2.83 A of current is drawn from the battery for 6.3 h? Pb(s) + PbO2(s) + 2H+(aq) + 2HSO4−(aq) ¡ú 2PbSO4(s) + 2H2...

A concentration cell is constructed of two hydrogen electrodes. The pressure of H2 is 1.00 atm in each hydrogen electrode. One of the electrodes is immersed in a solution with [H+] = 1.0 M and the other in a solution with 0.62 M NH3. What will be the value of Ecell? (Hint: Fir...
