Given the following, which statement is TRUE? 2H* + 2e Pb2+ + 2e Ni²* + 2e Fe2+ + 2e Cr* + 3e Zn²+ + 2e K* + e -> H2 0.00v -> Pb -0.13v -> Ni -0.23v -> Fe -0.44v -> Cr -0.74v -> Zn -0.76v -> K -2.92v All of these metals will dissolve in 1.0M acid. Lead is the most easily oxidized metal on this list. Potassium metal dropped into 1M acid will form H2 gas. Zn will not dissolve in 1M acid. The hydrogen half-cell has zero voltage because it is always at equilibrium under standard conditions
