Use the Lewis dot structure (make sure you show all electron pairs) and VSEPR theory to predict which of the following molecules is polar.

A 25.00 mL sample of the sulfuric acid solution was titrated with 45.42 mL of a 0.9598 M solution of sodium hydroxide, NaOH. Use the equation below to find the stoichiometric (mole) ratio and apply it to calculate the molar concentration of the sulfuric acid, H2SO4. H2SO4(aq) + 2 NaOH(aq)   →  Na2SO4(aq) + 2 H2O(l)
