Use the References to access important values if needed for this question. A sample of krypton gas at a pressure of 1.02 atm and a temperature of 167°C, occupies a volume of 587 mL. If the gas
is heated at constant pressure until its volume is 849 mL, the temperature of the gas sample will be
°C.

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
