2 HCl + Zn --> ZnCl2 + H2
When you use 25 ml. of 4.0 M HCl to produce H2 gas, how many
grams of zinc does it react with?

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

Deposition is the transition of matter going from gas to solid without passing through the liquid phase.a.) gas—-> solid
