Using the thermodynamic data below, and a value of -717 kJ/mol for the Ulattice enthalpy for KCl, calculate the ionization energy of K. Hint: Remember to plug in numbers to the equation given in course content.
Enthalpy of ionization K = +89 kJ/mol
Enthalpy of formation KCl(s) = -437 kJ/mol
Enthalpy of formation Cl(g) = +121 kJ/mol
Electron affinity of Cl(g) = -349 kJ/mol
Assuming that the total pressure of the gases is 1.52 and that their mole ratio is 94 : 4.0 : 1.5 : 0.50, calculate the partial pressure (in atmospheres) of each gas.
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?
A voltaic cell is set up at 25º C with thefollowing half cells: Al3+ (0.0010 M) | Al and Ni2+(0.50 M) | Ni. Write an equation for the reaction that occurs when the cellgenerates an electric current and determinethe cell potential.
if you have 430.00 ml of water at 25.00 degrees celcius.and add 100 ml of water at 95.00 degrees celcius, what is the final temperature of the mixture?
would that be the same kind of functional group linking monosaccharides in long chain polysaccharides
