Lake Michigan is a very large, very deep body of water, located in a region of the United States that gets quite cold in winter. On the coldest day of last year, what was the temperature at the bottom of Lake Michigan? explain your answer in terms of the density of water.
Draw the mechanism of Grignard Synthesis of Malachite Green. (Ensure that all mechanistic arrows are correctly drawn.) Show the following
After the Ketone react with sodium borohydride in ethanol. HCl be added dropwise, and then remove the ethanol by distillation, then add DCM and ice water.
The normal boiling point of bromine is 58.8°C. Given that the vapor pressure of methanol is 75.0 torr at 2.5°C, calculate the molar enthalpy of vaporization of bromine.
If delta H for the reaction is -851.5 kJ/mol at 25'C, calculate the standard free energy change, delta G for the reaction at 25'C. Calculate the temperature at which the reaction changes from spontaneous to non-spontaneous.
130 mL of an HCl solution with pH of 3.90 is added to 200 mL of an HNO3 solution. The resulting solution is 1.40 mL. What was the pH of the original HNO3 solution?
