- Ethanol, C2H5OH, is produced industrially from ethylene, C2H4, by the following sequence of reactions: 3C2H4+2H2SO4C2H5HSO4+( C 2 H 5)2SO4C2H5HSO4+( C 2 H 5)2SO4+3H2O3C2H5OH+2H2SO4 What volume of ethylene at STP is required to produce 1.000 metric ton (1000 kg) of ethanol if the overall yield of ethanol is 90.1%?arrow_forwardThe barometric pressure measured outside an airplane at 9 km (30,000 ft) was 266 torr. Calculate the pressure in kPa.arrow_forwardEthanol, the alcohol used in automobile fuels, is produced by the fermentation of sugars present in plants. Corn is often used as the sugar source. The following equation represents the fermentation of glucose, the sugar in corn, by yeast to produce ethanol and carbon dioxide. C6H12O6(aq)2C2H5OH(aq)+2CO2(g) Ethanol is combusted in an automobile engine according to the equation C2H5OH(l)+3O2(g)2CO2(g)+3H2O(g) What would be the total volume of CO2 gas formed at STP when 3.00 kg of sugar is fermented and the ethanol is then combusted in an automobile engine?arrow_forward
- The chlorofluorocarbon CCl2F2 can be recycled into a different compound by reaction with hydrogen to produce CCl2F2(g), a compound useful in chemical manufacturing: CCl2F2(g)+4H2(g)CH2F2(g)+2HCl(g) (a) Outline the steps necessary to answer the following question: What volume of hydrogen at 225 atm and 35.5 C would be required to react with 1 ton (1.000103kg) of CCl2F2? (b) Answer the question.arrow_forward5.16 If the atmospheric pressure is 97.4 kPa, how much is it in mm Hg? In atm?arrow_forward59 During a collision, automobile air bags are inflated by the N2 gas formed by the explosive decomposition of sodium azide, NaN3: 2NaN32Na+3N2 What mass of sodium azide would be needed to inflate a 30.0-L bag to a pressure of 1.40 atm at 25 C?arrow_forward
- Before small batteries were available, carbide lamps were used for bicycle lights. Acetylene gas. C2H2, and solid calcium hydroxide were formed by the reaction of calcium carbide, CaC2. with water. The ignition of the acetylene gas provided the light. Currently, the same lamps are used by some cavers, and calcium carbide is used to produce acetylene for carbide cannons. (a) Outline the steps necessary to answer the following question: What volume of C2H2 at 1.005 atm and 12.2 C is formed by the reaction of 15.48 g of CaC2 with water? (b) Answer the question.arrow_forward5-114 Carbon dioxide gas, saturated with water vapor, can be produced by the addition of aqueous acid to calcium carbonate based on the following balanced net ionic equation: (a) How many moles of wet CO (g), collected at 60.°C and 774 torr total pressure, are produced by the complete reaction of 10.0 g of CaCO3 with excess acid? (b) What volume does this wet CO2 occupy? (c) What volume would the CO2 occupy at 774 torr if a desiccant (a chemical drying agent) were added to remove the water? The vapor pressure of water at 60.°C is 149.4 mm Hg.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
- Consider a 5.00-L tank containing 325 g of H2O at a temperature of 275 C. (a) Calculate the pressure in the tank using both the ideal gas law and the van der Waals equation. (b) Which correction term, a(n/V)2 or bn, has the greatest influence on the pressure of this system?arrow_forwardAmmonium nitrate can be used as an effective explosive because it decomposes into a large number of gaseous products. At a sufficiently high temperature, ammonium nitrate decomposes into nitrogen, oxygen, and steam. (a) Write a balanced net ionic equation for the decomposition of ammonium nitrate. (b) If 2.00 kg of ammonium nitrate are sealed in a 50.0-L steel drum and heated to 745C, what is the resulting pressure in the drum after decomposition? (Assume 100% decomposition.)arrow_forwardAn organic compound contains C, H, N, and O. Combustion of 0.1023 g of the compound in excess oxygen yielded 0.2766 g CO2 and 0.0991 g H2O. A sample of 0.4831 g of the compound was analyzed for nitrogen by the Dumas method (see Exercise 129). At STP, 27.6 mL of dry N2 was obtained. In a third experiment, the density of the compound as a gas was found to be 4.02 g/L at 127C and 256 torr. What are the empirical and molecular formulas of the compound?arrow_forward
