When Zn reacts with HCl solution, the products are H2 gas and ZnCl, Part A Zn(s) + HCI(aq)-→H2(g) + ZnCl2 (aq) What was the partial pressure of the H2 gas? A volume of 418 mL of H2 gas is collected over water at a total pressure of 779 mmHg and 16 °C. The vapor pressure of water at 16 °C is 14 mmHg. Express your answer to three significant figures and include the appropriate units. P = 765 mmHg Submit Previous Answers v Correct Since a sample collected over water is a mixture of the gas desired (H2 here) and water vapor, the total pressure is the sum of the pressures of both gases. By subtracting the pressure contributed by the water vapor (14 mmHg) from 779 mmHg , the pressure of the H2 gas can be calculated. Part B How many moles of H2 gas were produced in the reaction? Express your answer with the appropriate units. HA ? Value Units P Pearson
