Given the reaction Fe O2 Right arrow. Fe2(3 )O3(2-), what happens to the oxidation states of these elements? Fe O.

Ithink is a because if say increased in electronegativity

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

  super sorry but i dont know lo

5.6⋅10−^19  j

do you need the explaination?
