Section Exercises 1.8.1 Phosphorus trichloride is produced from the reaction of solid phosphorus and chlorine gas: P4 + 6 Cl2 + 4 PC13 a. What mass of phosphorus trichloride can be prepared from 75.0 g of phosphorus? b. What mass of chlorine will be consumed in the reaction? 1.8.2 Tooth enamel consists, in part, of Ca5 (PO4)3 (OH). Tin(II) fluoride (also called stannous fluoride) is added to some toothpastes because it exchanges F- for OH to give the more decay-resistant compound fluoroapatite, Caz(PO4)3F In addition, this reaction produces tin(II) oxide and water. What mass of Ca(PO4)3(OH) can be converted to Ca5(PO4)3F by reaction with 0.115 g of tin(II) fluoride? 1.8.3 Combustion reactions require molecular oxygen. In an automobile the fuel-injection system must be adjusted to provide the right “mix” of gasoline and air. Compute the number of grams of oxygen required to react completely with 1.00 L of octane (C8H18, which has a density p=0.80 g/mL). What masses of water and carbon dioxide are produced in this reaction? NEED MORE PRACTICE? Try Problems 1.61 and 1.62
