3. A student investigated the stoichiometry of the reaction of zinc (Zn) with HCl solution and reported the following data. When 0.2158 g of Zn reacted with 10.00 mL of 1.000M HCI, 82.062 g of water was displaced. A total of 36.00 mL of 9.501 x 10 M NAOH solution was required to titrate the HCI remaining in the reaction mixture at the end of the reaction. The room temperature was 27.0°C and the barometric pressure was 777 torr. The gram atomic mass of Zn is 65.38 g mol-1. The density of water at 27.0 °C is 0.9965 g mL- and its vapor pressure is 27.0 torr. R = 8.21 × 10 2 L-atm K mol. (Hint: See Calculations.) (1) Calculate the volume of the displaced water from its mass. Note that the volume of the water will be equal to the volume of the gas collected. 109/ U5,4 91M

Below is a description of a double displacement reaction between the reactants, lead (II) nitrate and potassium iodide, to form the products, lead (II) iodide and potassium nitrate. Lead (II) nitrate and potassium iodide are both semi-crystalline white solids that when dissolved in water forms a clear solutions. If these two solutions are combined, a banana yellow opaque mixture is created. The resulting solution is filtered to collect the banana yellow lead (II ) iodide precipitate. The filtrate containing the potassium nitrate byproduct is a clear and colorless solution.
