Get started for freeDetermine the oxidation number of each atom in \(\mathrm{CaCO}_{3} .\)
Write the balanced half-reaction for the change of \(\mathrm{O}_{2}(a q)\) to \(\mathrm{H}_{2} \mathrm{O}(l)\) in acidic solution.
The standard electrode potential for the reduction of \(\mathrm{Zn}^{2+}(a q)\) to \(\mathrm{Zn}(s)\) is \(-0.762 \mathrm{V}\) . What does this value indicate?
Explain what half-reactions are and why they are useful.
A fuel cell uses methanol, CH \(_{3} \mathrm{OH},\) as fuel. Assuming complete oxidation of the fuel to \(\mathrm{CO}_{2}\) and \(\mathrm{H}_{2} \mathrm{O}\) in acidic aqueous solution, how many electrons are transferred per \(\mathrm{CH}_{3} \mathrm{OH}\) molecule?
