Illustrate (draw) the thermodynamic cycles for the acid dissociation of both HCl and HF. Classify each cycle as exergonic or endergonic. Do your calculated values agree with the observed strengths of each acid in water? Use the given experimental values below to answer this part of the question:
The aqueous solvation enthalpy of H+ is -1091 kJmol-1. The solvation energy of HX(g) ? HX(aq) is approx. -40 kJmol-1. The ionization energies of HCl(g) and HF(g) are 1393 kJmol-1 and 1553 kJmol-1 respectively.
consider the reaction CO2+H2=CO+H2O.The equilibrium concentrations are [CO]= 0.050M, [H2]=0.045M, [CO2]=0.086M, and [H2O]= 0.040M. Calculate K .
The average person generates about 2500 Kcal of heat a day. How many kilowatt-hours of energy is this? If walking briskly dissipates energy at 500 W, what fraction of the day's energy does walking one hour represent.
The piece of iron with a mass 102.9g was submerged in a graduated cylinder filled with water. The initial level of water was 20.0 ml. The density of iron is 7.86 g/ml.
What is the emf for this cell when [Fe3+] = 0.50M, PH2 = 0.25 atm, [Fe2+] = 0.010M and the pH in both compartments is 4.00
Really confused on calculating/finding the half-equivalence point in a titration curve. This was a lab experiment done in my chem lab. We added 0.0750 M NaOH to acetic acid (pipet 10.00mL of ~0.1M HCH3CO2 into the beaker and add 40mL of DI water).
How many grams of Fe(NO3)3 · 9 H2O are required to prepare 300.0 mL of a 0.249 M solution of Fe(NO3)3 · 9 H2O?
Environmental magazine about the success of global initiatives in solving environmental concerns, using the Montreal Protocol and ozone depletion as a focus.
Synthesizing ethers via acid-catalyzed condensation reactions has limited usefulness. The conditions (sulfuric acid and heat) are also conducive to elimination products. Clarification of Organic Chemistry
A 12 m 11 m 3.0 m basement had a high radon content. On the day the basement was sealed off from its surroundings so that no exchange of air could take place.
For each alkene, indicate the direction of the dipole moment. For each pair, determine which compound has the larger dipole moment. a) cis-1,2-difluoroethene and trans-1,2-difluorothene
A sample of gas is collected over water at a temperature of 35.0C when the barometric pressure reading is 763 torr. What is the partial pressure of the dry gas, given PH2O =42.2 torr?
