Suppose a reaction was run that produces hydrogen gas and a sample of h2(g) collected. as a result of the collection 145 ml of water is displaced. the pressures of the gas and atmospheric pressure are equalized using the method described in this experiment. the atmospheric pressure is 745 mm hg. the temperature of the water and gas are identical at 22 c/ how many moles of h2 have have been evolved?

C: plants and animals

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
