Find the electronic configuration for ionization energies of Magnesium, the orbital number in which the electrons are added in phosphorus ion, and the one will lose in the ionization of Alluminium.
1. The reasoning of why racemic mixtures are not exactly 50-50 of an SN1 reaction.
2. Explain why benzylic and allylic halides undergo SN2 reactions the fastest.
The tripeptide alanyllysylaspartate contains four ionizable groups with pKas of 2.0, 3.9, 9.9, and 10.5. Calculate the pI for this molecule.
how heavy in pounds is a gold bar at Fort Knox (dimensions of 7.0 in x 3 5/8 in x 1 3/4 inches? If the current price for gold is $1400 per troy ounce, how much is 1 bar of gold worth in ? (make sure you look up troy ounce!)
A buffer that contains 0.347 M of a base, B and 0.483 M of its conjugate acid BH+, has a pH of 8.08. What is the pH after 0.00713 mol of HCl are added to 0.442 L of the solution
Derive the rate law, and show that this reaction may follow the first-order equation at high pressures and the second-order equation at low pressures.
Nitrogen gas reacts with hydrogen gas to make ammonia(NH3). 15.5 L of N2 reacts at STP to make 30 L of ammonia. What is the percent yield?

What is the bond angle and molecular geometry around the 2 middle carbon atoms?
A student heats 5.128 g sodium bicarbonate to completely decompose the sample to sodium carbonate. 3.2349 g of sodium carbonate was produced. Calculate the atom economy of this reaction.
0.554g sample that is a mixture of oxalic acid, H2C2O4 and another solid that does not react with sodium hydroxide. If 29.58 mL of 0.550 M NaOH is required to titrate the oxalic acid in the 0.554g sample to the equivalence point
Why would it be more appropriate to put the elements La and Ac in the bottom two periods and put Lu and Lr in the transition metals? Why don't we see the use of any sublevels higher than the f sublevel?
How many grams of ethylene glycol C_2H_6O_2 must be added to 1.00 kg of water to produce a solution that freezes at -3.44 C?
Crude gunpowders often contain a mixture of potassium nitrate and charcoal (carbon). When such a mixture is heated until reaction occurs, a solid residue of potassium carbonate is produced.
