Bam makes a second solution, adding 6.4 g of Co(CH3COO)2 to 44.66 mL of H2O. Calculate the concentration of this solution in mole fraction.

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

The answer is fossil fuels.

Ican't see the chart but the density of both nickel and cobalt is 8.90 g/cm3, so it would be one of those.
