(a)
Interpretation:
The evidence has to be given for the octane rating is not a measure of the energy content of a gasoline.
Concept introduction:
Octane rating or octane number:
It is a measurement of the performance or quality of gasoline. If the octane rating is high, the fuel burns within the engine of a vehicle is better.
(b)
Interpretation:
The importance of octane ratings in measure a fuel’s ability to minimize or prevent engine knocking has to be explained.
Concept introduction:
Octane rating or octane number:
It is a measurement of the performance or quality of gasoline. If the octane rating is high, the fuel burns within the engine of a vehicle is better.
(c)
Interpretation:
The reason has to be explained for the higher octane blend is more cost than lower octane.
Concept introduction:
Octane rating or octane number:
It is a measurement of the performance or quality of gasoline. If the octane rating is high, the fuel burns within the engine of a vehicle is better.
(d)
Interpretation:
The fuel contains oxygenates or not has to be identified when the octane rating of 91 (premium gasoline).
Concept introduction:
Octane rating or octane number:
It is a measurement of the performance or quality of gasoline. If the octane rating is high, the fuel burns within the engine of a vehicle is better.

Chemistry In Context
- Calculate the amount of carbon dioxide (in kg) emitted into the atmosphere by the complete combustion of a 15.0 gallon tank of gasoline. Do this by following these steps: Assume that gasoline is composed of octane (C8H18). Write a balanced equation for the combustion of octane. Determine the number of moles of octane contained in a 15.0 gallon tank of gasoline (1 gallon = 3.78 L). Octane has a density of 0.79 g/mL. Use the balanced equation to convert from moles of octane to moles of carbon dioxide, then convert to grams of carbon dioxide, and Finally to kg of carbon dioxide.arrow_forward4.60 Why are fuel additives used?arrow_forwardA newspaper article states that biomass has actually been used as an energy source throughout human history.

- The best solar panels currently available are about 15% efficient in converting sunlight to electricity. A typical home will use about 40. kWh of electricity per day (1 kWh = 1 kilowatt hour; 1kW = 1000 J/s). Assuming 8.0 hours of useful sunlight per day, calculate the minimum solar panel surface area necessary to provide all of a typical homes electricity. (See Exercise 124 for the energy rate supplied by the sun.)arrow_forward4.1 List at least two factors that make it difficult to describe the combustion of gasoline accurately.

- Calculate how many grams of each of the following would be required to produce 7.8 X 103 KJ of energy a. pine wood b. octane c. ethanol d. coal e. natural gasarrow_forwardPropane (C3H8) is the commonly used fuel in our barbeques at home. It is a great fuel because it will release 2220 kJ of energy for every mole that combusts. A. Write the balanced reaction for the combustion of propane. B. When 50.0g of propane cobusts, how much energy is released? C. Is this reaction exothermic or endothermic? Provide evidence.arrow_forwardThey are all part of one question. Ethanol, C2H6O, is most often blended with gasoline - usually as a 10 percent mix - to create a fuel called gasohol. Ethanol is a renewable resource and ethanol-blended fuels, like gasohol, appear to burn more efficiently in combustion engines. The heat of combustion of ethanol is 326.7 kcal/mol.The heat of combustion of 2-methylhexane, C7H16, is 1.150×103 kcal/mol. How much energy is released during the complete combustion of 495 grams of 2-methylhexane ? ______kcalAssuming the same efficiency, would 495 grams of ethanol provide more, less, or the same amount of energy as 495 grams of 2-methylhexane? Hydrocarbons, compounds containing only carbon and hydrogen, are important in fuels.The heat of combustion of cyclohexane, C6H12, is 936.8 kcal/mol.Write a balanced equation for the complete combustion of cyclohexane. + + How much energy is released during the complete combustion of 364 grams of cyclohexane ? _______kcal Combustion…arrow_forward
