Therefore carbohydrates are covalent compounds. Since electrons or more specifically valence electrons from their respective atoms are shared to form chemical bonds and acquire greater chemical stability from the bonds, this is present through out this biological macromolecule and is thus covalent.
When battery discharge / delivering current the lead at the anode is oxidized
that is ;
pb---->pb+ 2e-
since the lead ions are in presence of aquous sulfate in insoluble lead sulfate precipitate onto the electrode
the overall reaction at the anode is therefore
Pb + SO4^2- ---> PbSO4 + 2e-
