Cars are powered by lead-acid batteries and the electrochemical cell processes are described the following net redox reaction: Pb(s) + PbO2(s) + 2H2SO4(aq) → 2PbSO4(s) + 2H₂O(1) Identify which ONE of the following statements is CORRECT? O a. Lead as both the metal and in the ionic compound is reduced and hydrogen is oxidised. O b. Lead as both the metal and in the ionic compound is oxidised and hydrogen is reduced. O c. Lead in the ionic compound is reduced and metallic lead is oxidised. d. Lead as both the metal and in the ionic compound is oxidised and oxygen is reduced. O e. Oxygen is oxidised and lead as both the metal and in the ionic compound is reduced.
