A car battery produces electrical energy with the following chemical reaction.
Pb + PbO2 + 2H2SO4 →; 2PbSO4 + 2H20
What is the mole ratio of PbO2 to water?
PbO2:H,0 = 1:



Answer :

It has a 1:2 ratio
If you look at the start of PbO2 it does not have a number so that is the one and if you look at 2H2O that has a 2 in front so that is where you get the 1:2 ratio
