7. Transition elements come from the d block. Examples of d block elements are manganese, cobalt, iron, copper, scandium and zinc. (a) Write the electron configurations for the atoms and ions of manganese and cobalt below. Mn atom: 1s? Co2* ion: 1s? (b) When iron is added to copper (II) sulfate solution, the iron displaces the copper ions from solution. However, when copper is added to iron (II) sulfate solution, the iron ions are not displaced and they remain in solution. (i) Write the half equation for the reduction of copper (II) ions to form copper.) (ii) Explain why the reaction takes place only if iron is added to copper (II) sulfate solution.

Hi, For part B it says its incorrect, can you please explain me and how the right drawing? Thank you :)
Any phd experts there??? Question 34. In the course material you have been introduced to multiple charging for electrospray spectra. Each peak in the spectrum below can be used to provide a measure of the mass of this protein, you can work out the charge associated with each peak, and measures can be averaged to find the overall mass. Use simultaneous equations to find the charge associated with each peak in the spectra below, which will allow you to calculate the average mass of each species. Include an estimate of the error associated with this measure. Graph for Intrpt. Below is samples see calculation etc
