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

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
