2C2H6 + 702 + 4CO2 + 6H2O AH = - 2125 KJ/molrxn
Is this reaction exothermic or endothermic?

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

Radioactive fallout is a result of the fission creation used to ignite the thermonuclear fusion reaction.
