chapter 6 assignment 2

Chapter 6 Task 2: All steps required 1. Photosynthesis reactions in green plants use carbon dioxide and water to produce glucose and oxygen according to the following chemical equation: 6CO2 + 6H20CH,206 + 602 A plant has 44.0 g of carbon dioxide and 32.0 g of water available for photosynthesis. a) Which is the limiting reactant? b) What mass of glucose would be produced in this reaction? 2. The following reaction takes place in an alkaline battery. I Zn(s) + 2MnO2(s) + H2O(1) Zn(OH)2(s) + Mn,O3(s) a) Determine the limiting reactant if 25.0 g of Zn and 30.0 g of MnO2 are used. Assume there is excess H2O(l). b) Determine the mass of Zn(OH)2 produced. - 3. When an antacid tablet dissolves in water, the fizz is due to a reaction between sodium hydrogen carbonate, NaHCO3, and citric acid, H,C6H5O7. Both substances are present in the tablet. 3NaHCO3(aq) + H2C6H307(aq) - 3CO2(g) + 3H2O(l) + NazC6H5O2(aq) What mass of NazC6H50, can be produced if one tablet containing 1.00 g of NaHCO3 is dissolved? 4. Phosphorus pentachloride, PC15, is used to add chlorine to organic compounds. It is a dangerous compound because it reacts violently with water. Phosphorus pentachloride can be produced by the following reaction: P.(s) + 10C12(g) + 4PC13(g) If 23.0 g of Preacts with 16.0 g of Cly, which reactant is limiting? 5. The ore hematite, Fe2O3, is an important source of iron. The iron is extracted by reacting the hematite with carbon monoxide, according to the following reaction: TAI Fe,O3(s) + 3CO(g) 2Fe(s) + 3CO2(g) a) If 1 mol hematite reacts with 6 mol carbon monoxide, which reactant is the limiting reactant? b) What amount (in mol) of iron would be produced
