The O-H stretch of a concentrated solution of an alcohol occurs at a lower frequency than the O-H stretch of a dilute solution.
Write ionic and net ionic equations for the following reactions. (Use the lowest possible coefficients. Include states-of-matter under SATP conditions in your answer.)
why was nortripyline measured here? was there post-mortem redistribution? Explain.Were amitriptyline and nortriptyline over the toxic dose? Acute overdose/rapid death or chronic administration/show death? Explain
Your stock solutions are 20% glucose, 1M tris and 0.5M EDTA. The diluent is distilled water. Determine how much of each you will add to make the desired buffer.
A mixture is prepared by adding 50.0 mL of 0.200 M NaOH to 75.0 mL of 0.100 M NaOH. What is the [OH-]? the answer is .140 M
Consider an electrolysis cell that might be used to electroplate nickel onto other metal surfaces. Label the anode and the cathode
suppose you have 10 ml of 0.10m sucrose solution. you add 90 ml of water to the solution.Do the number of sucrose change? Does the molarity change?
Consider the halide ions as nucleophiles. Briefly explain why F-, the strongest base among the halide ions, is the best nucleophile in polar aprotic solvents while iodide the weakest base is the best in protic solvents.
Rank the following compounds in order of reactivity toward nitration with HNO3
A calorimeter containing 200.0 mL of water was calibrated by carrying out a reaction which released 15.6 kJ of heat. If the temperature rose 3.25 degrees celcius then the heat capacity of the calorimeter inclusing the water is?
If 156 mL of wet H2 is collected over water at 24C and a barometric pressure of 736 torr, how many grams of Zn have been consumed?
