Answer the following question: Answer the following question given this paragraph: Sulfuric acid is the industrial chemical produced in greatest quantity worldwide. About 90 billion pounds are produced each year in the United States alone. Write the Lewis structure for sulfuric acid, H2SO4, which has two oxygen atoms and two OH groups bonded to the sulfur. 7.5 Strengths of Ionic and Covalent Bonds 64. Which bond in each of the following pairs of bonds is the strongest? (a) CC or C = C (b) CN or C N (c) C O or C = O (d) HF or HCl (e) CH or OH (f) CN or CO 65. Using the bond energies in Table 7.2, determine the approximate enthalpy change for each of the following reactions: (a) H 2(g) + Br 2(g) 2HBr(g) (b) CH 4(g) + I 2(g) CH 3 I(g) + HI(g) (c) C 2 H 4(g) + 3O 2(g) 2CO 2(g) + 2H 2 O(g) 66. Using the bond energies in Table 7.2, determine the approximate enthalpy change for each of the following reactions: (a) Cl 2(g) + 3F 2(g) 2ClF 3(g) (b) H 2 C = CH 2(g) + H 2(g) H 3 CCH 3(g) (c) 2C 2 H 6(g) + 7O 2(g) 4CO 2(g) + 6H 2 O(g) 67. When a molecule can form two different structures, the structure with the stronger bonds is usually the more stable form. Use bond energies to predict the correct structure of the hydroxylamine molecule:. Q: What is the industrial chemical produced in greatest quantity worldwide? A:
