Compute the wavefunction and the probability to tunnel, for a proton in the potential: V(x)=0, when x< -0.20 nm, and x>0.00 nm, and V(x)=2.0*10-19 J otherwise. Consider this wavefunction to have a total energy of 1.2 eV, and its functional form in the x>0.00 region to be psi(x)=exp(i*k*x).
wo aliquots of serum are added to 5.00 mL portions of water. To one portion is added 20.0 microL of 0.0750 M KCl solution. The net emission signals in arbitrary units are 23.2 and 68.6, What is the magnitude of the emission signal produced by the s..
Gaseous C2H4 reacts with O2 according to the following equation: C2H4(g) +3O2(g) --> 2CO2(g) + 2H2O(g). What volume of oxygen at STP is needed to react with 1.50 mol of C2H4
Write the electron configuration of the atom in the third row of the periodic table that has the largest difference between the third and fourth ionization energies.
4.20 g of a chloride-containing compound of Ti was obtained. What is the empirical formula of the chloride-containing compound
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.
The density of an unknown gas is 4.00 grams per liter at 4.00 atmospheres pressure and 127 degrees C. What is the molecular weight of the gas?
formation of a compound cannot be truly explained. What is your view on this topic? Are there any other factors that should be considered?
what is the pressure exerted onto the closed end of an apparatus if the atmospheric pressure is 720 torr and the height of the water is 22.3 cm.
Assuming the density of a 5% acetic acid solution is 1.0 g/ml, determine the volume of the acetic acid solution necessary to neutralize 25.0 ml of .10M NaOH. Also record this calculation on your report sheet.
Give the repeating unit of the polymers prepared by ADMET polymerization
Using the same assumptions and approximations you used in lab, determine the molar enthalpy change (in kJ/mol) for the reaction below, assuming that CH3CO2H dissociates completely in water.
The pressure increased as the gaseous reaction PCl5 1 PCl3 +Cl2 occurred. When equilibrium was achieved, the pressure in the tube had increased to 1.25 atm. Calculate Kp.
