You will have 90 minutes to complete this exam. and report answers with correct units and number of significant figures for full credit. A periodic table is included on the last page of the exam. PV = nRT R = 0.08206L middot atm/mol middot K 1 atm = 760 mmHg 1 L middot atm = 101.3 J h = 6.626 times 10^-34 J middot s Hydrogen gas is produced by the reaction of Zn(s) with HCI(aq) according to the following balanced chemical equation. Zn(s) + 2HCI(aq) rightarrow ZnCI_2 (aq) + H_2 (g) If 0.105 g of zinc are reacted with an excess of hydrochloric acid at STP (0 degree C and 1.00 atm), what volume of hydrogen gas is produced, n liters? b. In a separate experiment, an unknown amount of line is reacted with excess HCI, and the gas produced is collected over water at a pressure of 755 mmHg. If a total volume of 52.0 mL of gas is collected, i) what is the partial pressure of the hydrogen gas. and ii) what was the mass of the original sample?
