1. Property of Ethanol Molecular formula: C2H50H
Colorless, inflammable liquid
Burns with smokeless blue flame
Hydroxyl group  Hydrogen Bonding
Ethylene Hydration and Fermentation
Flash point: 13°C
Density: g/cm3

2. Property of Gasoline Molecular formula: C8H18
Yellow color, volatile and inflammable liquid
Vaporizes at the low temperature
Burns with black smoke and red flame
Oil refineries (distillation)
Flash point: 43°C
Density: g/cm3

3. Combustion of Ethanol C2H50H(l) + 3O2(g)  2CO2(g) + 3H20(l)
50 L of Ethanol ≈ 50000cm3
50000 × = 39450g
Number of Ethanol moles: 39450÷46.08 ≈ moles
Mole ratio of Ethanol and CO2 gas – 1:2
Number of CO2 moles: moles
Amount of CO2 gas produced
mol × 44.01g = g
≈ kg

4. Combustion of Gasoline
C8H18(l) O2(g) = 8CO2(g) + 9H2O(l)
50L of Gasoline ≈ 50000cm3
50000 × = 36000g
Number of Gasoline moles: 36000÷ ≈ moles
Mole ratio of Gasoline and CO2 gas – 1:8
Number of CO2 moles: moles
Amount of CO2 gas produced
mol × 44.01g = g
≈ kg
