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...

Magnesium-aluminum alloys are commonly used in aircraft construction. When treated with acid, both metals react to form hydrogen gas, as shown in the unbalanced chemical equations below. A 1.000 g sample of alloy produces 0.107 g of H2 (g) when reacted with excess HCl (aq). What is the percent composition by mass of Al in the alloy? Al (s) + HCl (aq) à AlCl3 (aq) + H2 (g) Mg (s) + HCl (aq) à MgCl2 (aq) + H2 (g)

A 1.268 g sample of a metal carbonate (MCO3) was treated with 100.00mL of 0.1083 M sulfuric acid (H2SO4), yielding CO2 gas and an aqueous solution of the metal sulfate (MSO4). The solution was boiled to remove all the dissolved CO2 and was then titrated with 0.1241 M NaOH. A 71.02 mL volume of NaOH was required to neutralized the excess H2SO4. What is the identity of the metal M?

1.53 g of aluminum metal is placed in a Erlenmeyer flask with 1.5 M sulfuric acid. The hydrogen gas produced from the reaction is collected over water as seen in the diagram below. The aluminum is allowed to react with the sulfuric acid until it stops reacting. There is still some unreacted aluminum left in the reaction flask. The gas in the collection flask is brought to the same atmospheric pressure as the surroundings, 765.25 torr and a temperature of...
