White gas is a mixture of C5 compounds and C6 compounds. The heavier hydrocarbons in white gas are hexanes (C6H14).
a. Calculate the fuel value of C6H14, given that ?Hdegreescombustion = -4163 kJ/mol
b. How much is the heat released during the combustion of 5.00 kg of C6H14?
c. How many grams of C6H14 are needed to heat 1.00 kg of water from 29.5 degrees celsius to 77.5 degrees celsius? Assume that all of the heat released during the combustion is used to heat the water.
d. Assume white gas is 25% C5 hydrocarbons (fuel value=48.99 kJ/g) and 75% C6 hydrocarbons. How many grams of white gas are needed to heat 1.00 kg of water from 29.5 degrees celsius to 77.5 degrees celsius?
