43. Answer the following questions using principles of chemical bonding and molecular structure.
(a) Consider the carbon dioxide molecule, CO2, and the carbonate ion, CO3²-
(ii) Account for the fact that the carbon-oxygen bond length in CO3²- is greater than the carbon- oxygen bond length in CO₂.
(b) Consider the molecules CF4, and SF4.
(i) Draw the complete Lewis electron-dot structure for each molecule.
