CO2 is produced in a 1.75 L container at 751 mmHg and 35oC by combustion ethanol (C2H6O), how many mL of ethanol was used in this combustion? (density of ethanol is 0.789 g/mL). a) 4.78 mL b) 0.399 mL c) 3.78 mL d) 4.00 mL e) 2.00 mL
Calculate the heat released when 135 grams of ethanol C2H5OH, burns. The heat of combustion of ethanol is 1233 kJ/mol. Molar mass of ethanol C2H5OH = 46.07 g/mol C2H5OH(g) + 3 O2(g) → 2 CO2 (g) + 3 H2O(l) LaTeX: \DeltaΔH = -1233 kJ/mol
QUESTION 3 How much heat (in kJ) is required to raise the temperature of 122 g of ethanol (mw 46.07) from 11.29 °C to its boiling point of 78.37 °C and then vaporize it completely creating ethanol gas at the boiling temperature? (specific heat - 2.46 J/g°C, AHyap = 48.6 kJ/mol) QUESTION 4 What is the change in enthalpy (in kJ) when 40.1 g of ethanol (mw-46.07) is condensed at its boiling temperature? (specific heat 2.46 J/g°C, AHvap 48.6 kJ/mol)...
