Given the following pair of half-reactions, fill in the line notation for a standard cell using these two half-reactions. Since it is a standard cell, all concentrations will be 1 M, so do not enter concentrations. You have solid platinum (Pt) electrodes to use, where necessary. Do not include the physical state of the components, i. e., solid platinum would just be Pt. For subscript and superscripts use the model: Ag+ would be Ag^+ and SO42- would be entered as SO4^2-, with the "^" character indicating a superscript. Leave a space between components. Ag+ (aq) + e- → Ag (s) ξo = 0.80 CO3+(aq) + e- → Co2+(aq) ξo = 1.82

answer: your mm

i think it's letter a.

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
