Determine the electrochemical potential and the free-energy change for a system where a solution of 0.1 M Mn2 at pH 1 is shaken in air at 0.2 bar pressure of O2, resulting in produc- tion of MnO2 (s), with the reduction of the oxygen to water. If the pH is held constant at 1 and the oxygen pressure at 0.2 bar, what will be the equilibrium concentration of Mn2 in the presence of excess MnO2 (s)

Which of these statements explains the difference between nuclear binding energy and the strong nuclear force ?

How can one make a supersaturated solution? (apex)

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
