Practice with Hess's Law and Standard Heats of Formation 1. (Example) The reaction C2H4 (g) + 6 F2 (g) → 2 CF4(g) + 4 HF (g) can be written as the sum of: C2H4 (9) ► 2 C(s) + 2 H2 (g) AH = -52.3 kJ/mol 2 C(s) + 4 F2 (9) ► 2 CF4(9) AH = -1360 kJ/mol 2 H2(g) + 2 F2 (g) → 4 HF (a) AH = -1074 kJ/mol C2H4(g) + 6 F2(g) → 2 CF4(g)...
Synthetically produced ethanol is an important industrial commodity used for various purposes including: as a solvent (especially for substances intended for human contact or consumption); in coatings, inks, and personal-care products; for sterilization; and as a fuel. Although a great deal of attention has been given to the production of ethanol by fermentation of sugars, industrial ethanol is a petrochemical synthesized by the hydrolysis of ethylene: C2H4 (9) + H20 (v) = C2H5OH (v) Some of the product is converted...
1. A scientist measures the standard enthalpy change for the following reaction to be -2913.0 kJ: 2C2H6(g) + 7 O2(g)->4CO2(g) + 6 H2O(g) Based on this value and the standard enthalpies of formation for the other substances, the standard enthalpy of formation of H2O(g) is kJ/mol. 2. A scientist measures the standard enthalpy change for the following reaction to be -138.6 kJ : H2(g) + C2H4(g)->C2H6(g) Based on this value and the standard enthalpies of formation for the other substances, the...
