Chapter 10 Solutions
Chemistry, Loose-leaf Edition (8th Edition)
- 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)arrow_forwardWhen two cotton plugs. one moistened with ammonia and the other with hydrochloric acid, are simultaneously inserted into opposite ends of a glass tube that is 87.0 cm long, a white 1111g of NH4Cl forms where gaseous NH3 and gaseous HC1 first come into contact. NH3(g)+HCl(g)NH4Cl(s) At approximately what distance from the ammonia moistened plug does this occur? (Hint: Calculate the rates of diffusion for both NH3 and HCI, and find out how much faster NH3 diffuses than HCI.)arrow_forwardCalculate H when a 38-g sample of glucose, C6H12O6(s), burns in excess O2(g) to form CO2(g) and H2O() in a reaction at constant pressure and 298.15 K.arrow_forward
- Use the kinetic theory to justify the following observations: (a) the rate of a reaction in the gas phase depends on the energy with which two molecules collide, which in turn depends on their speeds; (b) in the Earth’s atmosphere, light gases, such as H2 and He, are rare but heavier gases, such as O2, CO2, and N2, are abundant.arrow_forwardNitroglycerine ( C,H,N,O,) is a very strong explosive that degrades over time and is too shock sensitive to transport safely. Dynamite is made by combining nitroglycerine with stabilizers and adsorbents, which makes it much safer to use. The explosion of nitroglycerin can be represented by: 4 C,H,N,O,() → 6 N2(9) + 12 CO(9) + 10 H,0(9) + 7 O2(9) A stick of 40% dynamite is about 20 cm long and about 3 cm in diameter and weighs 241 grams. It is 40.0% nitroglycerine by mass. What is the total number of moles of gas produced when a stick of 4o% dynamite explodes? mol gasarrow_forwardThe atmosphere slowly oxidizes hydrocarbons in a number of steps that eventually convert the hydrocarbon into carbon dioxide and water. The overall reaction of a number of such steps for methane gas is:CH4(g) + 5 O2(g) + 5 NO(g) ------> CO2(g) + H2O(g) + 5 NO2(g) + 2 OH(g) Suppose that an atmospheric chemist combines 155 mL of methane at STP, 885 mL of oxygen at STP, and 55.5 mL of NO at STP in a 2.0-L flask. The flask stands for several weeks at 275 K. If the reaction reaches 90.0% of completion (90.0% of the limiting reactant is consumed), what is the partial pressure of each of the reactants and products in the flask at 275 K? What is the total pressure in the flask?arrow_forward
- Propane (C3H8) is sold in metal cylinders for use in portable camp stoves. The complete combustion of propane in air can be described by the following equation: C3H8(g)+5O2(g)-->3CO2(g)+4H2O(g). Using the ideal gas law estimate the volume (in liters) of air (at 20 degrees Celsius and 0.92 atm) required for combustion of 1.36 moles of propane assuming air is 20.0% (by volume) O2arrow_forwardOxygen gas can be generated by heating potassium chlorate: heat 2KCIO, (s) 2KCI(s) + 30, (g) What volume of oxygen gas, collected by displacement of water and measured at 750.1 torr and 80.0 °C (vapor pressure of water 80.0 °C -355.63 torr), will be formed by the decomposition of 19.3 g of potassium chlorate? Be sure your answer has the correct number of significant figures. Note: Reference the Conversion factors for non-SI units and Fundamental constants tables for additional information.
