A round bottom flask containing 30g of water at 25 C is attached to a vaccum line. The pressure in the flask is reduced until water in the flask begins to boil. Under these circumstances determine if G, H, S sys, S total are positive, negative or zero
How do glucagon and epinephrine block fatty acid biosynthesis. How does insulin activate fatty acid biosynthesis
Calculate the pH of a solution prepared by mixing equal volumes of 0.21M methylamine (CH3NH2), Kb = 3.7X10^-4 and 0.61M CH3NH3Cl
Which of the following cannot act as a Brønsted-Lowry base in an aqueous solution? a) ammonia, NH3 b) acetate ion, CH3CO2-
The Ka for hypochlorous acid (HClO) is 3.0 x 10?8. What is [OH?] in a 0.145 M solution of sodium hypochlorite (NaClO)
A 706 mL gas sample at STP is compressed to a volume of 248 mL, and the temperature is increased to 39?C. What is the new pressure of the gas in Pa.
The volumes listed correspond to the ½ equivalence point, equivalence point, 1 ½ equivalence point, and 2 equivalence point. The pH will equal pKa2 at the 1 ½ equivalence point, which is 11.55. Therefore, the [H+] = 10^(-11.55) = 2.81 x 10-12
