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.
