Question 1 Titanium(IV) oxide, TiO2, is a common solid found in everything from thin-film solar cells to whitening toothpaste. A common method to synthesize this compound is through the reaction between liquid titanium(IV) chloride, TiCl4(1), and water vapor, H₂O(g). Calculate the heat, in J, released by the conversion of 2.922 g TiCl4. TiCl4 (1) + 2 H₂O(g) →TiO2 (s) + 4 HCl (g) AH = -25.4 kJ Question 2 1 pts 1 pts Most of the world's aluminum comes from processing the mineral, bauxite, whose chemical formula is Al2O3, into aluminum metal. How many kilojoules of heat are required to convert 14.72 kg bauxite into solid aluminum? Al2 O3 (8) 2 Al (s) + O₂ AH = 1676 kJ
Question 3 Hydrogen gas can be synthesized from coal and water vapor according to the equation shown below. C(s) + H₂O(g) → CO(g) + H2 (9) AH = 131.3 kJ - How many kilojoules of heat are required to make 7.056 moles of hydrogen gas from excess reactants? Question 4 The reactions of nitrogen oxides are important in the environment and in industrial processes. Calculate the heat transferred, in kJ, when 58.5 g of O2 gas reacts with excess nitrogen monoxide to form solid dinitrogen pentoxide. 4 NO(g) + O₂ (9) 2 N₂O5 (s) AH = -219 kJ 1 pts 1 pts
