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...
