Problem: Practice Set 2 Energy Released by Combustion

I. Isooctane (C8H18; d = 0.698 g/mL) is used as the fuel in a test of a new automobile drive train.

i. How much energy (in kJ) is released by combustion of [12.1] gal of isooctane to gases (?Hrxn = -5.44 x 10^3 kJ/mol)?

ii. The energy delivered to the automobiles at 65 mph is 5.5 x 10^4 kJ/h. Assuming all the energy is transferred as work to the wheels, how far (in km) can the vehicle travel on the [12.1] gal of fuel?

II. A [33.1] g sample of the radiator coolant ethylene glycol releases [717] J of heat. What was the initial temperature of the sample if the final temperature is 32.5°C (717 of ethylene glycol = 2.394 J/g K)

III. An FM station broadcasts music at [89.9] MHz (megahertz or 106 Hz). Find the wavelength (in m, nm, and A) of these waves.

IV. How fast must a [184] baseball travel to have a de Broglie wavelength equal to that of an x-ray photon with ? = 100 n
