Now 3 The combustion of octane to form carbon dioxide and liquid water can be written as: CH3(g) +2502(g) → 8C02(g) +9H, O(1) AH = -5450kJ mol-1 The combustion of octane to form carbon dioxide and water vapour can be written as: C2H18(8)+ 25 02(g) → 8C02()+9H, O(g) How would the energy released by the combustion of 1 mol of octane to form water vapour compare with the energy released by 1 mol of octane to form liquid water? 5
Combustion of hydrocarbons such as octane (CH) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's atmosphere can trap the Sun's heat, raising the average temperature of the Earth. For this reason there has been a great deal of International discussion about whether to regulate the production of carbon dioxide. 1. Write a balanced chemical equation, including physical state symbols, for the Combustion of liquid octane into gaseous carbon dioxide and gaseous water 3 2. Suppose 0.250 kg...
Part A The combustion of gasoline produces carbon dioxide and water. Assume gasoline to be pure octane (C8H18) and calculate the mass (in kg) of carbon dioxide that is added to the atmosphere per 2.3 kg of octane burned.
