The heat of combustion of ethanol, C2H5OH(l), is -1367 kJ/mol. A batch of sauvignon blanc wine contains 11.2 % ethanol by mass.
Assuming the density of the wine to be 1.0 g/mL, what is the caloric content due to the alcohol (ethanol) in a 6-oz glass of wine (177 mL)?

For the unbalanced combustion reaction shown below, 1 mol of ethanol, C2H5OH, releases 327 kcal (1370 kJ). C2H5OH+O2→CO2+H2O How much heat (in kilocalories) is released from the combustion of 7.38 g of ethanol? How many grams of C2H5OH must be burned to raise the temperature of 360.0 mL of water from 20.0 ∘C to 100.0 ∘C? (The specific heat of water is 1.00 cal/g⋅∘C or 4.184 J/(g⋅∘C). Assume the density of water at 20.0∘C is 1.00 g/mL.

The heat of combustion of heptane and isooctane are -4501 kJ/mol and -5100 kJ/mol, respectively. Isooctane (2,2,4-trimethylpentane, pronounced iso-octane) is a pretty good model for the complex mixture of hydrocarbons that is gasoline. The density of these two liquids (essentially the same for all liquid hydrocarbons) is 0.7 g/mL (kg/dm3). What is the heat of combustion of one gallon of the two liquids? Are they essentially the same or quite different? Why? a. b. The U.S. Congress (our representatives) mandated...
