IB Chemistry: Further covalent bonding questions

1. The bonding in sulfur trioxide is sometimes explained by sulfur expanding its octet to six pairs of outer electrons (by using available d orbitals) to give three S=O double bonds.It is also sometimes explained by keeping to the ‘octet rule’ where only eight outer electrons around the central sulfur atom are involved. Draw the resonance hybrids to illustrate this model of bonding and explain why all the S–O bonds...
