What is E∘cell for a galvanic cell constructed from aluminum and silver electrodes? Report your answer with three decimal places. Half Reaction E∘ (V) Mn2+(aq)+2e−⟶Mn(s) −1.185 Zn(OH)2(s)+2e−⟶Zn(s)+2OH−(aq) −1.245 Zn2+(aq)+2e−⟶Zn(s) −0.7618 Al3+(aq)+3e−⟶Al(s) −1.662 Mg2+(aq)+2e−⟶Mg(s) −2.372 Ba2+(aq)+2e−⟶Ba(s) −2.912 K+(aq)+e−⟶K(s) −2.931 Ag+(aq)+e−⟶Ag(s) +0.7996 Au3+(aq)+3e−⟶Au(s) +1.498 Provide your answer below:

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom

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
