What are the reactants and pruducts when isooctane and oxygen burn to form carbon dioxide and water?
reactants: isooctane & oxygen products: carbon dioxide & water
How many moles of Oxygen are needed to completely react with 4 moles of isooctane?
To determine how many moles of oxygen are needed to completely react with isooctane (C₈H₁₈), we can use the balanced combustion reaction: 2 C₈H₁₈ + 25 O₂ → 16 CO₂ + 18 H₂O. From this equation, 2 moles of isooctane react with 25 moles of oxygen, indicating that 1 mole of isooctane requires 12.5 moles of oxygen. Therefore, for 4 moles of isooctane, 4 × 12.5 = 50 moles of oxygen are needed.
What does a gasoline octane rating of 93 mean?
it has 93 percent isooctane
One gallon of isooctane has a mass of 2.6 kg What is the change in enthalpy for the combustion of one gallon of this compound?
The change in enthalpy for the combustion of one gallon of isooctane can be calculated using the heat of combustion for isooctane, which is -5470 kJ/kg. Given the mass of one gallon (2.6 kg), the change in enthalpy would be -5470 kJ/kg * 2.6 kg = -14222 kJ.

What is the structure of isooctane?
Isooctane, also known as 2,2,4-trimethylpentane, has the chemical formula C8H18. Its structure consists of a five-carbon pentane backbone with three methyl (–CH3) branches attached to the second and fourth carbons. This branching contributes to its properties, including its high octane rating, making it a common reference fuel in the automotive industry. The molecular structure can be visually represented as a central chain of five carbon atoms with three additional methyl groups extending from it.
Most of the energy in an isooctane reaction is released in the form of?
Isooctane is an organic compound that is used in gasoline powered internal combustion engines. When it burns, it gives off heat. The heat makes gas expand and that pushes pistons down which makes the crankshaft turn. That makes the car move. Isooctane does not cause a gasoline engine to knock, which means it does not cause the gas-air mixture in a cylinder to burn before the spark plug ignites it. When an engine knocks, the mixture ignites in several places inside a cylinder and makes a knocking sound. Another chemical, heptane, causes an engine to knock. A mixture of octane and heptane is compared to another fuel to determine the octane rating of the other fuel. If the mixture is 90% octane (actually isooctane) and 10% heptane, then the fuel has an octane rating of 90. It is possible for a chemical to have an octane rating of over 100. In that case, the chemical is mixed with heptane until the percent is equal to 100% octane when the engine starts to knock. Then extrapolation is used.An engine with a 4:1 compression ratio can use a very low octane gasoline. An engine with an 8:1 compression ratio needs a high octane gasoline. An engine with a 12:1 compression ratio needs close to 100 octane.During world war 2, America went over to 100 octane gasoline and higher compression ratios. then its fighter aircraft became faster than German fighters.
