eccchhhhhhh!!! Is this AP Chem? Dx
Here's what I did.

a) Justify the choice of the solid sodium hydrogen carbonate to clean up the spill. Include relevant equations(s).
H2SO4+NaHCO3=CO2+H2O+NaSO4
500ml of H2SO4 (sulfuric acid) with 18molL-1 is 9 mols.
Balancing the rest of the equation gives you:
9(H2SO4)+18(NaHCO3)=18(CO2)+9(H2O)+9(Na2SO4)
Your products are then CO2 (harmless), H2O (even more harmless), and Na2SO4 (a precipitate).
b) Calculate the minimum mass of sodium hydrogen carbonate needed to neutralise the spilled acid completely.
