That is the titratable acidity of the sealion cove exhibit if a 50.0 mL water sample required 13.90 mL of 0.024 M sodium hydroxide to reach the titration endpoint. Report your answer in meq/L. Hint, you are basically calcualting the concentration of acidic protons (H+ in the reaction below) in millimoles per liter (mmol/L). H+(aq) + NaOH(aq) --> Na+(aq) + H2O(l)

Which of the following is true for the actual yield of a reaction? it is always calculated as a ratio. it is the yield from the excess reactant. it is the yield from the limiting reactant. it is always less than the theoretical yield.

What is the molar mass of the anhydrous compound? answer using four significant figures. 36.02 g/mol 120.15 g/mol 156.12 g/mol

You just calculated that the heat of fusion for chloromethane is 6400 j/mol. the heat of fusion for hydrogen is 120 j/mol.? which of the following account for this difference? more than one correcta. chloromethane can absorb more energy at the same temperature. b. hydrogen has stronger intermolecular forces than chloromethane. c. hydrogen molecules can pack more closely than chloromethane molecules. d. chloromethane experiences dipole-dipole interactions. e. chloromethane has a higher molar mass than hydrogen.
