(a) compute the voltage at 25°c of an electrochemical cell consisting of pure cadmium immersed in a 2  10-3 m solution of cd2+ ions, and pure iron in a 0.4 m solution of fe2+ ions. (b) write the spontaneous electrochemical reaction

Drive down any three characteristic of modern periodic table

Particles vibrate in a rigid structure and do not move relative to their neighbors.

In vapor-liquid equilibrium in a binary mixture, both components are generally present in both phases. how many degrees of freedom are there for such a system? the reaction between nitrogen and hydrogen to form ammonia occurs in the gas phase. how many degrees of freedom are there for this system? steam and coal react at high temperatures to form hydrogen, carbon monoxide, carbon dioxide, and methane. the following reactions have been suggested as being involved in the chemical transformation:
