A balloon containing 0. 500 mol Ar at 0. 00°C and 65. 0 kPa pressure is expanded by adding more argon. How many moles of argon are added to bring the sample to a final volume of 60. 0 L at 30. 0°C and 45. 0 kPa? What is the original volume of the gas? L.

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

Answer is (d)a brainliest would be appreciated

Idont know. if you want an answer you need to give us some context dude.
