- A 275-mL sample of CO gas is collected over water at 31C and 755 mmHg. If the temperature of the gas collection apparatus rises to 39C, what is the new volume of the sample? Assume that the barometric pressure does not change.arrow_forwardperform stoichiometric ca1cu1uions for reactions involving gases as reactants or products.arrow_forward5-25 A gas in a bulb as in Figure 5-3 registers a pressure of 833 mm Hg in the manometer in which the reference arm of the U-shaped tube (A) is sealed and evacuated. What will the difference in the mercury levels be if the reference arm of the U-shaped tube is open to atmospheric pressure (760 mm Hg)?arrow_forward
- The compression ratio in an automobile engine is the ratio of the gas pressure at the end of the compression stroke to the pressure in the beginning. Assume that compression occurs at constant temperature. The total volume of the cylinder in an automobile is 350 cm3, and the displacement the reduction in volume during the compression stroke is 309 cm3. What is the compression ratio in that engine?arrow_forward5-113 Ammonia and gaseous hydrogen chloride react to form ammonium chloride according to the following equation: If 4.21 L of NH3(g) at 27°C and 1.02 atm is combined with 5.35 L of HCI(g) at 26°C and 0.998 atm, what mass of NH4CI(s) will be generated?arrow_forward5-115 Ammonium nitrite decomposes upon heating to form nitrogen gas and water vapor according to the following unbalanced chemical reaction: When a sample is decomposed in a test tube, 511 mL Of wet N2(g) is collected over water at 26°C and 745 torr total pressure. How many grams of dry NH4NO2(s) were initially decomposed? The vapor pressure of water at 26°C is 25.2 torr.arrow_forward
- The barometric pressure measured outside an airplane at 9 km (30,000 ft) was 266 torr. Calculate the pressure in kPa.arrow_forwardA typical barometric pressure in Kansas City is 740 torr. What is this pressure in atmospheres, in millimeters of mercury, and in kilopascals?arrow_forwardThe density of liquid oxygen is about 1.4 g/cm3. Vaporized at 00C and 760 torr, this same 1.4 g occupies 980 cm3, an expansion of 700 times the liquids volume.arrow_forward
- Helium gas, He, at 22C and 1.00 atm occupied a vessel whose volume was 2.54 L. What volume would this gas occupy if it were cooled to liquid-nitrogen temperature (197C)?arrow_forward5-54 Automobile air bags are inflated by nitrogen gas. When a significant collision occurs, an electronic sensor triggers the decomposition of sodium azide to form nitrogen gas and sodium metal. The nitrogen gas then inflates nylon bags, which protect the driver and front-seat passenger from impact with the dashboard and windshield. What volume of nitrogen gas measured at 1 atm and 27°C is formed by the decomposition of 100. g of sodium azide?arrow_forwardA gas effuses through an opening one-fifth as fast as helium gas effuses through the same opening. (a) Is the gas heavier than helium? (b) What is the molar mass of the gas?arrow_forward
