Titanium (Ti) is an important material in manufacturing airplane 1. engines and frames. It is obtained from titanium tetrachloride (TiCIĄ), prepared from titanium dioxide, carbon, and chlorine through the following reaction: 3TIO2(s) + 4C(s) +6C2(g) à 3TIC4(g) 2CO2(g) + 2CO(g) a. If the reactor contains 11.34 g C, 13.56 g Cl2, and 8.3 g TiO2, identify the limiting reagent. b. Compute the theoretical yield of TICI4.

62 Ammonium dinitramide (ADN), NH4N(NO2)2, was considered as a possible replacement for aluminium chloride as the oxidizer in the solid fuel booster rockets used to launch the space shuttle. When detonated by a spark, AND rapidly decomposes to produce a gaseous mixture of N2,O2, and H2O. (This is not a combustion reaction. The ADN is the only reactant.) The reaction releases a lot of heat, so the gases are initially formed at high temperature and pressure. The thrust of the rocket results mainly from the expansion of this gas mixture. Suppose a 2.3-kg sample of ADN is denoted and decomposes completely to give N2,O2, and H2O. If the resulting gas mixture expands until it reaches a temperature of 100°C and a pressure of 1.00 atm, what volume will it occupy? Is your answer consistent with the proposed use of ADN as a rocket fuel?
Butane gas, C4H10, is sold to campers as bottled fuel. Its density at 25C and 1.00 atm is 2.38 g/L. What volume of butane gas at 25C and 1.00 atm is required to heat one gallon of water (d=1.00g/mL) from 25C to 98C ? The reaction for the combustion of butane (H f =125.6kJ/mol) is C4H10(g)+132 O2(g)4CO2(g)+5H2O(g)
The density of air at 20C and 1.00 atm is 1.205 g/L. If this air were compressed at the same temperature to equal the pressure at 50.0 m below sea level, what would be its density? Assume the barometric pressure is constant at 1.00 atm. The density of seawater is 1.025 g/cm3.
A gaseous hydrocarbon reacts completely with oxygen gas to form carbon dioxide and water vapour. Given the following data, determine Hf for the hydrocarbon: Hreaction=2044.5KJ/molhydrocarbonHf(CO2)=393.5KJ/molHf(H2O)=242KJ/mol Density of CO2 and H2O product mixture at 1.00 atm, 200.c = 0.751g/L. The density of the hydrocarbon is less than the density of Kr at the same conditions.
97 Homes in rural areas where natural gas service is not available often rely on propane to fuel kitchen ranges. The propane is stored as a liquid, and the gas to be burned is produced as the liquid evaporates. Suppose an architect has hired you to consult on the choice of a propane tank for such a new home. The propane gas consumed in 1.0 hour by a typical range burner at high power would occupy roughly 165 L at 25°C and 1.0 atm, and the range chosen by the client will have six burners. If the tank under consideration holds 500.0 gallons of liquid propane, what is the minimum number of hours it would take for the range to consume an entire tankful of propane? The density of liquid propane is 0.5077 kg/L.

Some solar-heated homes use large beds of rocks to store heat. (a) How much heat is absorbed by 100.0 kg of rocks if their temperature increases by 12C? (Assume that c=0.82J/gC.) (b) Assume that the rock pile has total surface area 2 m2. At maximum intensity near the earth's surface, solar power is about 170 watts/m2. (1watt=1J/s.) How many minutes will it take for solar power to produce the 12C increase in part (a)?
9.102 A runner generates 418 kJ of energy per kilometer from the cellular oxidation of food. The runner's body must dissipate this heat or the body will overheat. Suppose that sweat evaporation is the only important cooling mechanism. If you estimate the enthalpy of evaporation of water as 44 kJ/mol and assume that sweat can he treated as water, describe how you would estimate the volume of sweat that would have to be evaporated if the runner runs a 10-km race.
Octasulfur(S8) is the most common allotrope of sulfur and is widely used in the chemical industry, especially in the production of petroleum. While S8 is the main component of elemental sulfur on earth is can also be produced in the laboratory from the reaction of sulfur dioxide with hydrogen sulfide. The balanced chemical equation for this reaction is shown below: 8SO2(g)+16H2S(g)-----3S8(s)+16H2O(g) Consider the reaction of 93.0 grams of SO2 with 93.0 grams of H2S to answer the questions below. A. What is the limiting reagent? B. What is the excess reagent? C. How many grams of S8 can be formed? D. How many grams of excess reagent are left over?
4a Assume that worldwide combustion of fossil fuel accounts for an energy use of 500 x 1015 kJ/year. Also, assume that all fossil fuels can be represented by the formula C3H5 with energy content of 32,500 kJ/kg.Finally, assume that air is 79% N2 and 21% O2 , and has a molecular weight of 29 kg/kmol. i. Estimate the annual release of CO2 to the atmosphere by burning fossil fuels, in kg/yr ii. If all that CO2 entered the atmosphere (and none was removed), estimate the increase in atmospheric concentration, in ppm by volume. Assume the atmosphere contains 6.7 x 1018 kg of air.

The emission of NO2 by fossil fuel combustion can be prevented by injecting gaseous urea into the combustion mixture.
