You want to determine δh o for the reaction zn(s) + 2hcl(aq) → zncl2(aq) + h2(g) to do so, you first determine the heat capacity of a calorimeter using the following reaction, whose δh o is known:

The air is going to come out because of the low pressure.

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
