I need help I don’t get this

1) Convert pressure to atm
119 kPa x 1 atm/101 kPa = 1.18 atm

2) Convert temperature to Kelvin
35 + 273 = 308 K

3) Use PV=nRT and solve for V
(1.18 atm)(V)=(0.0972 mol)(0.0821)(308 K)

V = (0.0972 mol)(0.0821)(308 K) / (1.18 atm)

V = 2.08 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
