2. A deep underground cavern contains 2.24 x 106 Liters of methane gas at a pressure of 1500 kPa and a temperature of 42°C. How many grams of methane(CH.) does this gas
deposit contain?

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 it is also known as the completion state is untrue of the activation complex;
