Calculate Ecell for the reaction below 2AgBr(aq) + 2Hg(l) --> 2Ag(s) + Hg2Br2(s)

given the following standard reduction potentials

Hg2Br2(s) + 2e- --> 2Hg(l) + 2Br-(aq) E = +0.140 V

AgBr(aq) + e- --> Ag(s) + Br-(aq) E = +0.071 V

B. a graduated substance

False, as a substance changes from a solid to a liquid and from a liquid to a gas the molecules get farther apart from each other

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?
