What is the mole ratio of PbO2 to water in the chemical reaction of a car battery: Pb + PbO2 + 2H2SO4 ‚Üí 2PbSO4 + 2H2O?

Answer

Considering the stoichiometry of the reaction, the mole ratio of PbO‚ÇÇ to water (H‚ÇÇO) is 1:2. The balanced chemical equation is: Pb + PbO‚ÇÇ + 2 H‚ÇÇSO‚ÇÑ ‚Üí 2 PbSO‚ÇÑ + 2 H‚ÇÇO. In terms of the moles involved, we have: Pb: 1 mole, PbO‚ÇÇ: 1 mole, H‚ÇÇSO‚ÇÑ: 2 moles, PbSO‚ÇÑ: 2 moles, and H‚ÇÇO: 2 moles. This indicates that 1 mole of PbO‚ÇÇ produces 2 moles of water, confirming the mole ratio of PbO‚ÇÇ:H‚ÇÇO is indeed 1:2.
