... A cell is set up between the steel and the attached metal. Electrons flow to the half-cell at the more positive potential. The iron half-cell with E! = –0.44 V is at a more positive potential than the magnesium and zinc half-cells, and so electrons will flow from Mg and Zn to Fe2+. Magnesium and zin ...

... calculated by B3PW91/LANL2DZ(2f,p)* is more than halved, going from 283 kcal/mol in the gas phase to 119 kcal/mol in aqueous environment (PCM-H2O). While the dearth of reliable redox data for Au2+ species plus the crudity of our solvation model conspire to forestall quantitative comparisons, the cal ...

Partial molal volume is the increase in the volume of an infinite amount of solution (or an amount so large that insignificant concentration change will result) when 1 mole of component i is added. This is by no means equal to the volume of 1 mole of pure i. Partial molal volume is connected to othe ...
