Cell Diagrams

When writing cell diagrams based on balanced equations how do we know when to add Pt(s) onto each end of the reaction? For example, see 13b from chapter 14. (b) Ce4+(aq) + I-(aq) --> I2(s) + Ce3+(aq) the solutions say that the cell diagram is Pt (s) | I-(aq) | I2(s) || Ce4+(aq) | Ce3+(aq) | Pt(...

Re: Question about the Negative Sign in En = -hR/n^2

Yes, we would not express frequency or wavelength in terms of a negative number. However, when discussing change in energy, your value would be negative because energy is being released. Your final energy is less than your initial energy level.
