A chemist fills a reaction vessel with 0.623g mercurous chloride(Hg2Cl2) solid, 0.645M mercury (I) (Hg2^2+)aqueous solution, and 0.905M chloride (Cl-) aqueous solution at a temperature of 25.0°C.

Under these conditions, calculate the reaction free energy ΔG for the following chemical reaction:
Hg2Cl2(s) ⇌ Hg2^2+ (aq) + 2Cl^- (aq)

You are performing an experiment in a lab to attempt a new method of producing pure elements from compounds. the only problem is that you do not know what element will form. by your previous calculations you know that you will have 6.3 moles of product. when it is complete, you weigh it and determine you have 604.4 grams. what element have you produced?
