Organic chemistry question:
The combustion of gasoline produces CO2. T combustion of ethanol produces CO2. Why is ethanol considered to be a green alternative fuel when it produces CO2, just as traditional fuels do (CO2 is considered to be a greenhouse gas)? Your answer must address CO2 production.
Homework Answers
Combustion of gasoline equation:
2C8H18 + 25O2 ~> 16CO2 + 18H2O
So for every mol of octane (in gas) burned, 8 mol of CO2
areproduced
Combustion of ethanol equation:
1 CH3CH2OH + 3O2 ----> 2 CO2 + 3 H2O
For every mol of ethanol burned, 2 mol of CO2 are produced

5. 20% A 2.4-L gasoline fuelled internal combustion engine produces a maximum power of 220 kW when the fuel is burned stoichiometrically with air. The thermal efficiency of the engine at this maximum power is 43%. Methanol (CH3OH) is to be used as an alternative biofuel for this engine. The stoichiometric air-fuel ratio for gasoline is 14.6. Assume a combustion efficiency of 98%. The lower heating values of gasoline and methanol are 44 MJ/kg and 20 MJ/kg, respectively. Consider the...

Many power plants produce energy by burning carbon-based fuels, which also produces carbon dioxide. Carbon dioxide is a greenhouse gas, so over-production can have negative effects on the environment. Use enthalpy of formation data to calculate the number of moles of CO2(g) produced per megajoule of heat released from the combustion of each fuel under standard conditions (1 atm and 25 �C). Each must be in mol * MJ^-1 (a) coal, C(s, graphite) (b) natural gas, CH4(g); (c) propane, C3H8(g);...

Ammonia has been studied as an alternative "clean" fuel for internal combustion engines, since its reaction with oxygen produces only nitrogen and water vapor and in the liquid form it is easily transported. An industrial chemist studying this reaction fills a 25.0 L tank with 1.4 mol of ammonia gas and 1.6 mol of oxygen t 37.0°C. He then raises the temperature, and when the mixture has come to equilibrium measures the amount of water vapor to be 1.3 mol....

Please summarise below in a concise way. Alternative energy is studied as a result of the increasing costs of energy, the harm that fossil fuel may be costing the planet and the fact the energy demand is going up and the supply of fossil fuels may be going down. Energy and economic growth have always been going up, the more energy we consume, the more wealth we create as seen in the GDP of developed nations such as the USA,...

Consumers face a series of important questions when shopping for a new vehicle: Electric or hybrid? Petrol or diesel? Powerful or fuel-efficient? Sporty or economical? Yet for eco-minded consumers who seek the ultimate in green motoring, the decision to purchase a vehicle often comes down to one simple question: Where do I fill it up? Where to refuel is a perplexing issue for buyers of alternative-fuel vehicles. This is because cutting-edge green vehicles lack a nationwide fuelling infrastructure. The USA...

Question 1 The following gas phase reaction produces ethanol (C2H5OH) by catalytic hydrogenation of acetaldehyde (CH3CHO). The reaction reaches equilibrium at a temperature of T= T(N) and a pressure of 3 bar: CH,CHO(g) + H, (g) C,H,OH (8) The reactive system initially contains 1.5 moles of Hydrogen (Ha) for each mole of acetaldehyde (CH3CHO). The mixture is assumed to be an ideal gas. T(N) is the temperature corresponding to the student number as...
