Working from our Hamiltonian for hydrogen, what would be the Hamiltonian for He? In your Hamiltonian, label which term accounts for kinetic energy, the potential energy between the electrons and the nucleus, and the potential energy between the electrons. Keep in mind that Coulomb's law only applies to pairwise interactions, but that you can treat the nucleus as a single particle.
Detailed calculations show that the value of Z eff for the outermost electrons in Na and K atoms is 2.51+ and 3.49+ , respectively. What value do you estimate for Zeff experienced by the outermost electron in both Na and K by assuming core electro..
If a mixture of 14.0L of N2 and 24.0L of H2 are reacted, what volume of NH3 can be produced at STP?
How many antacid tablets should you give him if you want to neutralize all his stomach acid and explain your rationale for your answer. Include the balanced equation you used to determine your answer.
Calculate the equilibrium partial pressure of bromine gas. No approximations can be made because the equilibrium constant is too large.
The pKa of the alpha-carboxyl group of glutamine is 2.17 as well as the pKa of its alpha-amino group is 9.13. Compute the average net charge on glutamine if it is in a solution that has a pH of 8.40.
Calculate the concentration of the hydrochloric acid if a 15.0-mL sample is titrated with standard sodium carbonate solution. The titration required 10.00 mL of 0.350 mol/L sodium carbonate to neutralize the acid.
Despite his physical activity on his farm (he owns a pet tiger as well), a less than ideal lifestyle and acute love of Jack Daniels have finally taken their toll and Calvin is due to have liver transplant surgery very soon.
The half life of Uranium-238 is 4.5 x 10^9 yr. A sample of rock of mass 1.6 g is found to produce 29 dis/s. Assuming all the radioactivity is due to Uranium 238, find the percent by mass of Uranium 238 in the rock.

Determine the final concentration and Determine What mass of Ar is needed to exert half the pressure (at the same conditions of volume and temperature)?
What is the maximum mass in grams of NH3 that can be produced by the reaction of 1.0g of N2 with 3.0g of H2
Calculate the mass (in grams) of the product formed when 3.95 of Ba completely reacts. Assume that there is more than enough of the other reactant
