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).
the equilibruium constant Kc for the reaction A(g)+ B(g)----> C9(g) is 0.76 at 150C. If 0.800 mol of A is aded to 0.600 mol of B in a 1.00-L container at 150degrees C
Enter the sign of H° and S° for the condensation for CO2. Enter the sign as either + or -. Also indicate the temperature conditions (high temperature or low temperature) that favor condensation of CO2
How does the enthalpy change for the neutrlization of hydrochloric acid compare to the enthalpy change for the neutralization of aceitc acid. Explain any similarities or differences.
Calculate the theortical potential of the following cell. indicate if the cell as written is galvanic or electrolytic
A sample weighing 25g starts at 99 degrees celsius. It is put in a calorimeter containing 100g water. The water temperature begins at 20 degrees and both water and sample reach equilibrium at 32 degrees. What is the specific heat of the sample?
When HSCN is added, you expect that the equilibrium will shift to the right and the reaction mixture will become darker (more orange).
Using the calibration data provided below, calculate the concentration of cocaine (mg/mL) in the original urine sample.
A 530. g piece of copper tubing is heated to 92.0°C and placed in an insulated vessel containing 49.5 g of water at 39.5°C. Assuming no loss of water and heat capacity for the vessel of 10.0 J/K,
