What would the potential of a standard hydrogen electrode (S. H.E.) be under the given conditions? [H+]=0.78 MH2=2.2 atm=298 K

=
V

8.7 degrees celsius and 15.6 degrees fahrenheit

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na

Electrons are emitted

It will appear as o2(g) as a reactant
