For questions 1-5, consider a beaker containing an unknown quantity of NaHCo,(s). After being dissolved in 200 mL of water, hydrogen chloride gas is added to the resulting solution and a reaction occurs, consuming all the hydrogen chloride. The carbon dioxide generated is collected over water at 20.0 â¡C and 760 torr. NaHCO (aq)+ HCIg)* NaCI(aq)+H00)+CO.g) 1 If0.00500 moles of Co(g) are collected, what volume of CO, was collected over water? The vapor pressure of water at 20.00C is 17.54 mmHg. A. 0.120 L 2.Which of the reactants ionize completely in water? A. NaHCO,(aq) and HCI(g) B. HCI(g) B. 8.40 mL C. 0.123 L D. 0.126 L C. NaHCO.(aq) D. Neither of these e3. What is the molarity of sodiunm chloride at the end of the reaction? Assume the water generated has a negligible effect on the total volume. A. 0.250 M B. 2.50 x 10-2 M C. 2.50 x 103 M D. 2.50 x 10- M HC The hydrogen chloride gas was originally introduced from a gas cylinder at a pressure of 30 atm. What volume did the reacting hydrogen chloridegas takeupat30 atrm at 20 â¬C? 4. Pe. 3004 T 20âã93k A. 2.74 x 104L B. 4.01 x 103L C. 40.1 mL D. 17.3 ml X 5.
