17. Consider the following reaction: 4Al(s) + 302(8) 2A1,03(s)
It takes 2.00 L of pure oxygen gas at STP to react completely with a certain sample of
aluminum. What is the mass of aluminum reacted?
18. ​

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
