Helium and lithium are two elements that differ only in one electron. Why do you think they exhibit such different chemical and physical behavior?
Why is food irradiated with gamma rays from a Cobalt-60 source? Does the food become radioactive? Discuss your answer.
Is carbon dating more appropriate to measure the age of materials that are a few years old, or a few thousand years old or a few million years old?
For this assignment you will undertake an analysis based on a self-designed fictitious study that utilizes statistical analyses. You will first develop a fictitious problem to examine. It can be anything.
Give the relationship between standard free energyand equilibrium constant.The relationship between standard free energy and equilibrium constant is given by?GO= -R Tln(K)Where?GOis the std.
Discuss the applicability of each model - Does it differ based on the interactions you would expect for each model. Can you conclude that one of the models is 'better' than the others from your graphs/analysis in Problems 3.1-2?
The Soave-Redlich-Kwong equation is a commonly used cubic equation of state, second in popularity only to the Peng-Robinson Equation of state. In this problem, just derive the two equations (7.66) given in the problem.

The unit cell for Cr2O3 has hexagonal symmetry with lattice parameters a = 0.4961 nm and c = 1.360 nm. If the density of this material is 5.22 g/cm3, calculate its atomic packing factor.
The heat capacity at constant pressure of hydrogen cyanide is given by the expression Cp[J/(mol ·°C)] = 35.3 + 0.0291T(°C) (a) Write an expression for the heat capacity at constant volume for HCN, assuming ideal gas behavior.
Wet air containing 4.0mole% water vapor is passed through a column of calcium chloride pellets. The pellets adsorb 97.0% of the water and none of the other constituents of the air. The column packing was initially dry and had a mass of 3.40kg, fol..
List the formulas of three soluble bromide salts and three insoluble bromide salts. Do the same exercise for sulfate salts, hydroxide salts, and phosphate salts (list three soluble salts and three insoluble salts).
Discuss how transmission electron microscopy (TEM) can provide information complementary to that which can be obtained from standard X-ray or neutron diffraction methods, giving suitable examples.
