Aqueous hydrochloric acid reacts with magnesium to produce hydrogen gas according to the balanced equation below...
Aqueous hydrochloric acid reacts with magnesium to produce hydrogen gas according to the balanced equation below 2HCl (aq) + Mg (s) = MgCl2 (aq) + H2 (g) If 250.0 mL of 3.00 M HCl is combined with 9.92 g Mg, what volume of hydrogen gas can be produced? Assume the temperature and pressure of the gas are 25oC and 0.988 atm, respectively. ( R=0.08206 )
Hydrogen gas is produced by the reaction between metallic aluminum and aqueous hydrochloric acid. 2 Al(s)...
Hydrogen gas is produced by the reaction between metallic aluminum and aqueous hydrochloric acid. 2 Al(s) + 6 HCl(aq) — 2 AICI, (aq) + 3 H, (g) The hydrogen gas produced by this reaction is typically collected via water displacement. During this process, the hydrogen gas becomes saturated with water vapor. If 294.9 mL of gas with a total pressure of 1.33 atm is collected via water displacement at 29.4 "C, what is the partial pressure of the hydrogen gas...

When 0.40 g of impure zinc reacted with excess hydrochloric acid, 127mL of hydrogen gas were collected over water at 10 degrees C at a total pressure of 737.77 Torr. The vapor pressure of water at 10 degrees C is 9.21 Torr. The reaction in question is: Zn (s) + 2HCl (aq) --> ZnCl2 (aq) + H2 (aq) A.) what amount (in grams) of H2 gas was collected? B.) what is the percentage of purity of the zinc, assuming that...
