Hydrogen gas generated by the reaction of zinc and hydrochloric acid is collected via water displacement in an inverted graduated cylinder. THe pressure of the gas collected at 23oC is 99.750 kPa. If the reading from the gas collection cylinder is 0.750 L, how many moles of dry hydrogen were collected? The water vapor pressure at 23oC is 2.809 kPa.

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

Just took the quiz on edgenuity and the correct answer is "c.  4.54 x  10–12  j"
