In your Lewis structure for above, label all the bonds as sigma or pi. a) how many sigma and pi bonds are represented? 7. b) for the bonds between C and O in the Lewis structure on the previous page, de the type of orbitals that overlap to form that bond.

During an experiment sulfuric acid was spilled onto a bench, in order to clean the spill sodium bicarbonate is sprinkled on to the spill. Predict the products of the reaction shown below: H2SO4(aq)+2NaHCO3(s)⟶?H2SO4(aq)+2NaHCO3(s)⟶? a.) Na2SO4(aq)+H2O(l)+H2CO3(aq)Na2SO4(aq)+H2O(l)+H2CO3(aq) b.) No reaction c.) Na2SO4(aq)+2CO2(g)+2H2O(l)Na2SO4(aq)+2CO2(g)+2H2O(l) d.) Na3SO4(s)+CO2(g)+H2O(l)
