Non-metals and oxygen – Non-metals react with oxygen to form oxides. They often require heat to start the reaction. The oxides form acids when dissolved in water. For each element below provide the formula for the metal oxide and for the acid it forms when dissolved in water. S8(s) P4(s) C(s)

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
