Question

In the reaction, $SO_2$ (sulfur dioxide) acts as a Lewis acid because it accepts an electron pair, and $O^{2-}$ (oxide ion) from $CaO$ acts as a Lewis base because it donates an electron pair. This forms $CaSO_3$ (calcium sulfite). The formatting errors in the question seem to indicate these substances.
