Bond energy of ethanol
WebThe bond enthalpy D X–Y of a diatomic molecule X—Y is the enthalpy change for the (usually hypothetical) process: (8.6.1) XY ( g) → X ( g) + Y ( g) (8.6.2) Δ H o ( 298 K) = D x − y We have already used the term bond … WebVerified answer. engineering. To dramatize the loss of energy in an automobile, consider a car having a weight of 5000 lb that is traveling at 35 mi/h. If the car is brought to a stop, determine how long a 100-W light bulb must burn to expend the same amount of energy. (1 mi = 5280 ft.) Verified answer.

WebDec 9, 2024 · Bond breaking liberates energy, so we expect the ΔH for this portion of the reaction to have a negative value. Using the table, the single bond energy for one mole of H-Cl bonds is found to be 431 kJ: ΔH 2 = -2 (431 kJ) = -862 kJ By applying Hess's Law, ΔH = ΔH 1 + ΔH 2 ΔH = +679 kJ - 862 kJ ΔH = -183 kJ Answer
WebEthanol is able to form strong hydrogen bonds with water whereas ethanethiol does not have similar capability. The formation of hydrogen bonds increases the attraction between molecules of ethanol and molecules of water, making them more soluble in each other.
