Rewrite this measurement with a simpler unit, if possible.
1.4*kg*m^4*kg/kg^2*m

Ithink it’s 3 as the answer.

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

C) the increase in atmospheric pressure pushes the walls of the balloon outward thus making it  is the answer.hope i you.
