EBK INTRODUCTORY CHEMISTRY
- In the Mthode Champenoise, grape juice is fermented in a wine bottle to produce sparkling wine. The reaction is C6H12O6(aq)2C2H5OH(aq)+2CO2(g) Fermentation of 750. mL grape juice (density = 1.0 g/cm3) is allowed to take place in a bottle with a total volume of 825 mL until 12% by volume is ethanol (C2H5OH). Assuming that the CO2 is insoluble in H2O (actually, a wrong assumption), what would be the pressure of CO2 inside the wine bottle at 25C? (The density of ethanol is 0.79 g/cm3.)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_forward51 What volume of oxygen at 24 C and 0.88 atm is needed to completely react via combustion with 45 g of methane gas?arrow_forward
- What volume, in milliliters, of hydrogen gas at 1.33 atm and 33 C is produced by the reaction of 0.0223 g lithium metal with excess water? The other product is LiOH.arrow_forwardA 21.4-mL volume of hydrochloric acid reacts completely with a solid sample of MgCO3. The reaction is 2HCl(aq)+MgCO3(s)CO2(g)+H2O(l)+MgCl2(aq) The volume of CO2 formed is 159 mL at 23C and 731 mmHg. What is the molarity of the HCl solution?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
- A typical barometric pressure in Redding. California, is about 750 mm Hg. Calculate this pressure in atm and kPa.arrow_forwardA person exhales about 5.8 102 L of carbon dioxide per day (at STP). The carbon dioxide exhaled by an astronaut is absorbed from the air of a space capsule by reaction with lithium hydroxide, LiOH. 2LiOH(s)+CO2(g)Li2CO3(s)+H2O(l) How many grams of lithium hydroxide are required per astronaut per day?arrow_forward57 What volume of hydrogen gas, in liters, is produced by the reaction of 3.43 g of iron metal with 40.0 mL of 2.43 M HCl? The gas is collected at 2.25 atm of pressure and 23 C. The other product is FeCl2?arrow_forward
- Hydrogen cyanide (HCN) is a poisonous gas. It can be formed by the following reaction: H+(aq)+NaCN(s)HCN(g)+Na+(aq)What volume of 6.00 M HCl is required to react with an excess of NaCN to produce enough HCN to fill a room 12119 feet at a pressure of 0.987 atm and 72F?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_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
