What is the maximum number of electrons in an atom that can have the following set of quantum numbers? n = 4 l = 3 ml = -2 ms = +1/2 A. 0 B. 1 C. 2 D. 6 E. 10
Consider the reaction of 1-butanol with PCC (pyridinium chlorochromate). Draw only the organic product derived from 1-butanol. If the product is an ion, do not draw the counter ion. If the given reaction has more than one step, give only the final..
A buffer is to be prepared with a pH of 4.5 from 0.1M solutions of sodium acetate and acetic acid. How many mL of 0.1M NaAc would have to be added to 100mL of 0.1M HAc to make the proper buffer solution?
It takes 33 melt 3.51 joules to exactly 1 gram of H2O. What is the molar heat of fusion for water, from this data?

Use the standard half-cell potentials listed below to calculate the standard cell potential for the following reaction occurring in an electrochemical cell at 25°C.
The Calfhead stream (flow rate 0.05m3s-1) discharges into the Oxhead river (flow of 3.00 m3.s-1). It is proposed to discharge waste into the Calfhead stream but the EPA requires a stream mixing study be undertaken.
As NaOH is added to the column, the pH of the effluent is monitored carefully. After 2 mL of 0.4 M NaOH has been added, the effluent pH changes dramatically. Estimate the total column capacity in milliequivalents from this information.
