I Review Constants Periodic Table You may want to reference (Pages 349 - 353) Section 11.9 while completing this problem. Part A When Zn reacts with HCl solution, the products are H2 gas and ZnCl2: 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 n = Pearson

What is the concentration of helium dissolved in 3.5 L of water when enclosed in a sealed container and pressurized with 15 atm of helium gas? (kH(He) = 3.7 x 104 mol L-1 atm1) 0.019 mol/L O 0.0016 mol/L 0.056 mol/L O 0.0031 mol/L

Solve correctly please, need all subparts.
