When the reaction:         A + 2B 

For the reduction of silver with hydrogen:                              2Ag+(aq) + H2(g) → 2H+(aq) + 2Ag(s) Given the thermodynamic data in the table, what is the standard change in Gibbs free energy for this reaction at 298 K?

A multi-dimensional being reaches down to Earth and inserts you miraculously without harm at some random time and place in the Universe.  It is bright everywhere. You have been able to travel around, and it’s clear that you are not inside a star. Yet your surroundings seem as bright as looking directly at the Sun. As you travel around, you notice that you cannot find a single neutral atom anywhere, nor can you find any nucleus besides those of hydrogen and helium. While it is hot (a few thousand degrees Kelvin), it is nowhere near the temperature needed for nuclear fusion. Where are you?

What is the oxidation number of chromium in sodium dichromate, Na2Cr2O7?

For the oxidation of iron to form iron(III) oxide:                              4Fe(s) + 3O2(g) → 2Fe2O3(s)          ΔSo = –549.73 J∙K–1 at 298 K. The enthalpy of formation of Fe2O3(s) is –824.2 kJ∙mol–1.  What is the standard change in Gibbs free energy for this reaction at 298 K?
