A car battery produces electrical energy with the following chemical reaction. Pb+PbO_(2)+2H_(2)SO_(4)arrow 2PbSO_(4)+2H_(2)O What is the mole ratio of PbO_(2) to water? PbO_(2):H_(2)O=1:square

The balanced chemical equation given is:<br />\[ Pb + PbO_2 + 2H_2SO_4 \rightarrow 2PbSO_4 + 2H_2O \]<br />From the equation, we can see that 1 mole of \( PbO_2 \) produces 2 moles of \( H_2O \). Therefore, the mole ratio of \( PbO_2 \) to \( H_2O \) is 1:2.
