Question
9. Pure copper may be produced by the reaction of copper(l) sulfide with oxygen gas as follows: Cu,S(s) + O,(g) – 2Cu(s) + SO,(g) What mass of copper(I) sulfide is required in order to prepare 269.89 g of copper metal? Molar mass of Cu = 63.55g/mol Molar mass of Cu,S = 159.16g/mol 10. For the formation of 6.07 mol of water, how many moles of nitric acid are needed? Cu + HNO, - Cu(NO,), + NO + H,O Molar Mass: Cu: 63.55 g/mol H: 1.01 g/mol N:14.01 g/mol O: 16 g/mol 11. How many grams of oxygen can be obtained by the determination of 233 g of reactant in the following reaction: 2KCIO3 – 2KCI + 02 Molar Mass: K: 39.10 g/mol Cl: 35.45 g/mol O: 16 g/mol
