6. Given the data; AH®. C(s) = -394 kJ, AH®. H2g) = -286 kJ, AH®. C3H6(g) = -1911 kJ; wh: the standard enthalpy change for the reaction C3H6(g) - · 3C(9) + 3H2(g)? A. - 3951 kJ В. + 129 kJ C. + 1231 kJ D. – 129 kJ Questions 7 & 8 are based on the following information: The standard enthalpy change of formation of CO2 is -393.5 kJ mol-l. 7. What therefore is the standard enthalpy change of combustion of carbon in kJ moll? A. + 393.5 В. - 393.5 С.О D. + 787 8. What therefore is the standard enthalpy change of formation of carbon in kJ mol-l? A. +393.5 В.- 393.5 С.0 D. + 787 9. The successive ionization energies of element X are 900, 1720 and 15000 kJ. Which ic most likely to be present in the crystalline compound formed between X and fluorine? А. X 2+ В. X+ С. Х D. x 2- 10. Which of these conversions is a reduction? А. Fe(OH), — Fe(ОН), B. Ni → Ni?+ C. VO3 → VO²+ D. Clz — НОСІ
