10) Draw the energy diagram for the reaction H2+ I2<--> 2HI where the activation energy for the forward reaction is 38.9 KJ and the enthalpy change is +3.6 K).

Usually this mountain-building process produces majestic peaks and steep slopes. you should look for these along the other features.

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
