The equilibrium 3fe(s) c(s) → fe3c(s) is established in a solid solution. for such a solution, one can write an equilibrium constant expression in the usual way except that the concentrations that refer to solids in the solid solution are included. determine the equilibrium constant for the formation of cementite from iron and carbon at 680°c. (given: for this reaction at 25°c, δh°

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

The correct answer should be "electrons orbit the nucleus in circular motions exactly as shown on the classic bohr model."
