Pick any two normalized eigenfunctions of the particle in the box Hamiltonian. Show by direct integration that these functions are orthogonal functions.
A 93.7 g (5.20 mole) sample of water is heated to exactly 94.4 celsius. It is then added to 90.1 g (5.00 mole) of water at 22.5 celsius in a styrofoam cup calorimeter.
Water beads on the surface of a freshly waxed car hood. Use your knowledge of intermolecular forces to explain
Suppose that an excess of propane, C3H8 burns in 320 g of O2. How many moles of H2O will be formed
A solution is prepared by dissolving 179 g sucrose (C12H22O11) in enough water to produce 1.15 L solution. What is the molarity of this solution?
In which state is the average distance between molecules the greatest?, Explain the difference in densities at the two temps in terms of the kinetic molecular theory.
suppose that a student performing an experiment mistakenly calibrated the pH meter using pH 6 instead of a pH 7 buffer. As a result all pH meter readings were too low.
In the titration, 20.46 mL of the sodium hydroxide was used to react with 0.1082 grams of KHP. What is the molarity of the NaOH?
how many atoms are on the surface of the particle? What fraction of the gold atoms in the particle are on the surface?
If the Ksp of Fe(OH)2 is 7.9 × 10-16, what is the maximum [Fe2+] that can coexist with these solutes in the solution?
The vapor pressure of water at 20.0°C is 17.5mmHg . If the pressure of a gas collected over water was measured to be 453.0mmHg . What is the pressure of the pure gas
the ratio of the number of nuclei in the first excited nuclear energy level to the number of of nuclei for a nucleus with ε1 - ε0 = 1MeV at 25C. At what temperature is kBT on the order of ε1 - ε0. Note 1MeV = 10^6eV
If there's a mixture of O2 and N2, and the mol of N2 is 0.605 mol, and fraction (f) of O2 is 0.251; then, what is the mol of O2?
