I just don't know where to start with this one... Consider the following data for a substance:

Critical point: 113.7 atm and 550°C

Triple point: 0.109 atm and 113°C

Normal melting point: 1.00 atm and 123°C

What is the normal boiling point of the substance?

Enter your answer in units of °C to three significant figures.

The answer is c) pyrite

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
