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.

Fuel is burned in a boiler to produce saturated steam at 10.0 bar absolute pressure from saturated liquid water at 10.0 bar absolute pressure. This H20 flows through tubes that run through the boiler, Energy released by combustion is transferred as heat through the walls of the tubes to convert the liquid water to steam at 10.0 bar. The fuel consists of 37 mol% ethane and 63 mol% acetylene, and is fed in the vapor phase at 50 °C and...
