Based on your observations in the virtual lab, complete the data table. question 3 options: separated using a filter; mass separated using a magnet; magnetism separated using a filter; density separated using a filter; not soluble in water

D. or separated using a filter; not soluble in water. The sand is insoluble. Its like salt when you boil the water with salt, the water boils away then all you're left with is the salt. Same thing with sand.   

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
