Answer to Question #180237 in General Chemistry for Mariah

Question #180237

Write the balanced ionic equation and determine ΔE^o(cell) for the following half reaction equations:

2H⁺ (aq) + 2e^- --> H₂ (g) E^o = 0 V

Al⁺3 (aq) + 3e^- --> Al(s) E^o = -1.66 V

Expert's answer

"Al_ \n{(aq)}\n^{+3}\n\u200b\t\n +H_\n2\n\u200b\t\n \u2212\u2212>2H_\n{(g})\n+Al_\n{(s)}\n\t\n +e^ \n\u2212"

∆E°=-1.66-0 = -1.66V
