123 g of water is placed in an insulated cup, its initial temperature is 25.6°C. A 587.0 g sample of an unknown metal is heated. Its initial temperature is 125.0°C. The hot metal is added to the cold
water. The inal temperature of both is 39.3°C. Determine the Specific Heat of metal Identity the
metal?

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
