What are the reactants and pruducts when isooctane and oxygen burn to form carbon dioxide and water?
reactants: isooctane & oxygen products: carbon dioxide & water
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 its empirical formula isooctane?
I don't know the exact formula but, i know the density of iso-octane: 0.69 g/ml And one gallon is equal to 3,840 ml so.... all you need is the volume.
Is it possible to determine an octane rating from a vapour?
The octane rating of a substance is a measure of its resistance to autocombustion when compressed. By definition, isooctane has an octane rating of 100, and n-heptane a rating of 0, and all others are in comparison to these two.There are various ways to measure the octane rating of a substance. On way is determined by running the fuel through a specific test engine with a variable compression ratio under controlled conditions, and comparing these results with those for mixtures of isooctane and n-heptane.For other more information, and for the source of this information, see the Wikipedia link under the Web Links to the left of this answer.

What does a gasoline octane rating of 93 mean?
it has 93 percent isooctane
Is isooctane toxic?
Iso-octane is toxic only at high concentration.
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.
Is isooctane polar or non polar?
Isooctane is nonpolar because it has a symmetrical molecular structure with no significant difference in electronegativity between the carbon and hydrogen atoms. This results in a molecule that does not have a permanent dipole and does not interact strongly with other polar molecules.

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.
What element are in octane?
What most people mean when they talk about "octane" is slightly different from what a chemist means by the word (a layman's "octane" is a chemist's "isooctane", or 2,2,4-trimethylpentane). However, both octane and 2,2,4-trimethylpentane are hydrocarbons, meaning they contain exactly two elements: hydrogen and carbon.
What is octane number of a fuel?
Many car engines run on gasoline. If the octane is low, the engine will knock. If it is high, the engine will not knock, which means that sometimes it will make a knocking sound as you drive along. It also might keep running when you turn off the key to the car. With high octane, the engine also starts easier. It is more expensive to make high octane fuel. Lower octane fuel gets better milage. There are two organic chemicals: isooctane and heptane. Isooctane is a good fuel for cars. It is rated at 100 octane. Heptane is a bad fuel for cars. It is rated at zero octane. When gasoline is made, they need to make a certain octane. They put the gasoline in a car engine. They then run the car with a mixture of isooctane and heptane. They find the mixture that matches the batch of gasoline. That is the octane rating of the new batch of gasoline.
Why does gasoline conduct electricity?
In my knowledge, any liquid will conduct electricity. It was one of my first childhood lessons. Haha Fuel (gasoline) is made of hydrocarbons such as isooctane. Hydrocarbons itself has no free electrons, nor charges, so it is not conductive.
What is its empirical formula isooctane?
