4. Phosphorus pentachloride is the starting material for the production of certain polymers used to make artificial arteries and other prosthetic devices. It is made from elemental phosphorus, which in turn is produced from phosphate rock, Ca3(PO4)2. The equations are: 2 Ca3(PO4)2 (s) + 10 C (s) + 6 SiO₂ (s) → P4 (g) + 6 CaSiO3 (1) + 10 CO (g) P4 (s) + 10 Cl₂ (g) → 4 PC15 (s) What mass of chlorine (in kg) is required to react with the P4 produced from 1.20 kg of Ca3(PO4)2? Molar masses (g/mol): Cl₂ 70.91 Ca3(PO4)2 310.18

Amounts of tin may be alloyed with copper to produce bronzes of varying composition and properties. 8.9394 g of a particular bronze, compounded of only Cu and Sn, can be quantitatively converted into a 11.2311-g mixture of the Oxides CuO and SnO2. (Use the atomic masses: Cu 63.546, Sn 118.71, O 15.9994.) What was the percentage (by mass) of tin in the alloy?
Lead is found in Earth’s crust as several different lead ores. Suppose a certain rock is 38.0% PbS (galena), 25.0% PbCO3 (cerussite), and 17.4% PbSO4 (anglesite). The remainder of the rock is composed of substances containing no lead. How much of this rock (in kg) must be processed to obtain 5.0 metric tons of lead? (A metric ton is 1000 kg.)
Hemoglobin, a protein in red blood cells, carries O₂ from thelungs to the body’s cells. Iron (as ferrous ion, Fe²⁺) makes up 0.33 mass % of hemoglobin. If the molar mass of hemoglobin is 6.8x10^4g/mol, how many Fe²⁺ ions are in one molecule?

Phosgene, a substance used in poisonous gas warfare during World War I, is so named because it was first prepared by the action of sunlight on a mixture of carbon monoxide and chlorine gases. Its name comes from the Greek words phos (light) and genes (born of). Phosgene has the following elemental composition: 12.14% C, 16.17% O, and 71.69% Cl by mass. Its molar mass is 98.9 g/mol. (a) Determine the molecular formula of this compound. (b) Draw three Lewis structures for the molecule that satisfy the octet rule for each atom. (The Cl and O atoms bond to C.) (c) Using formal charges, determine which Lewis structure is the dominant one. (d) Using average bond enthalpies, estimate H for the formation of gaseous phosgene from CO(g) and Cl2(g).
