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 f
A reaction that is used to propel rockets is N2O4(l) + 2N2H4(l) --> 3N2(g) + 4H2O(g). This reaction has the advantage that neither product is toxic, so no dangerous pollution is released.
Assume that a solid has a constant of Cp,m=25 J/K-mol from 50K to 298K and that the DeBye approximation is valid from 0K to 50K. Estimate the standard molar entropy Sm for the solid at 298K.
30 mL of 0.25 M acetic acid are titrated with 0.05 M KOH. What is the volume of KOH needed to reach the equivalence point. A. 0.15 mL B. 150 L C. 150 mL D. 1.5 L
Equilibrium system given: Fe3+(aq) + SCN- (aq) <- -> FeSCN2+(aq) 1. Equilibrium system Net ionic equation 2. Equilibrium system + 1M Fe(NO3)3 Net ionic equation What stress caused the equilibrium to shift and in which direction it shift
assuming the end units will be Molarity as well. 13.1mL of AgNo3 solution are reacted with excess Na2CO3 solution to form AgCO3 precipitate. If 5.62mg of Ag2CO3 are formed, what was the original concentration
Calculate the pH of a 7.40×10^-1 M aqueous solution of sodium fluoride (NaF). (For hydrofluoric acid, HF, Ka = 7.20×10^-4)
To resolve an object in an electron microscope, the wavelength of the electrons must be close to the diameter of the object. What kinetic energy must the electrons have in order to resolve a protein molecule that is 7.00 nm in diameter? Take the m
List all possible bonds that can occur between the elements P, Cs, O, and H. Predict the type of bond (ionic, covalent, or polar covalent) one would expect to form for each bond.
How many mL of 0.425 M NaOH are needed to react completely with 25.0 mL of 0.250 M Fe Cl3 solution. FeCl3 aq + 3NaOH arrow to Fe(OH)3 aq +3NaCl aq
