The experimentally determined heat of combustion of ethanol is 1233 kJ/mol. Calculate the heat of combustion of ethanol in kJ/g. Molar mass of ethanol C2H5OH = 46 g/mol C2H5OH(g) + 3 O2(g) → 2 CO2 (g) + 3 H2O(l) LaTeX: \DeltaΔH = -1233 kJ/mol
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.
16) Ethanol, CHsO, is produced by the fermentation of sugars in wine and beer. Given that ethanol has a molecular weight of 46.07 g/mol and a density of 0.789 g/em answer the following questions: a) How many mL of ethanol are consumed in a 12 oz. glass of red wine that contains 13.4 % ABV? Note: ABV stands for alcohol (ethanol) by volume. You must use the following conversion factors in your calculation: 128 oz- 1 gal; 1 gal 3.785...
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...

A 2.11 g sample of ethanol (C2H5OH) is burned in a bomb calorimeter with a heat capacity, C-5.65 kJ/"C. C2H5OH() + 3 O2(g) + 2 CO2(g) + 3 H2O(g) AH'rxn=-1235 kJ If the initial temperature is 25.0°C, what is the final temperature (in "C) of the calorimeter? The molar mass of ethanol is 46.07 g/mol. Remember, in the heat equation, q=m's'AT, heat capacity is equivalent to Cum's, giving Heat capacity is extensive whereas specific heat is intensive. -CAT.
