For a voltaic cell based on the reaction below, what reaction happens at the anode? 2Ni3+(aq)+Cd(s)→2Ni2+(s)+Cd2+(aq) Ni3+(aq)+e-→Ni2+(aq) Ni2+(aq)→ Ni3+(aq)+e- Cd2+(aq)+2e-→Cd(s) Cd(s)→Cd2+(aq)+2e- A student measures the voltage across different metal electrodes placed in a voltaic cell. Using a copper cathode, the voltages when using a first a tin, then gold anode are positive and negative, respectively. The order of chemical reactivity of the solid metals must be Au>Cu>Sn Au=Sn Sn>Cu>Au Au=Sn>Cu

answer question 1 using table 1 provided
bellow:
1. Generate a reactivity series for the metals tested. E° = 0.34 V for the copper half-cell. Use this value to calculate Eº for each of the other half reactions. Write each half reaction as a reduction and arrange them with the most powerful reducing agent at the top of the table. When arranged in this manner, a metal on the right side of an equation will spontaneously react with a species...

Question #1. Place the metals: Pb, Ag, Zn, Cu and Mg in order of decreasing activity, most active first. Question #2. Why can you not place Hydrogen in its proper place in this order using the above information. Question #3. What test (metal and salt or acid) would you still need to do to place Hydrogen where it belongs in the activity order. There is no need to send me a photo, just email me your...

5. The nickel-cadmium battery, despite issues with the toxicity of Cd, is still used in some rechargeable batteries because it has very consistent voltage over long discharge times. a) Using only half-cell reactions given in Table 16.1, write the overall reaction and give the highest AV° value possible for a NiCd battery. b) The actual half-cell reactions used in a Nicd battery are: Ca(OH)2(8) + 2e → Cds + 2OH(aq) (Vº = -0.86V) NiO(OH)) + H2O) +e Ni(OH)2(s) + OH(aq)...
