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.

Is fusion an atomic process that is used to produce energy?
Fusion occurs when two atomic nuclei collide. The reaction that is produce by the collision can be used to provide energy. Fusion is the reaction that powers most active stars in the universe.
What nuclear reaction combines gas to form helium and produce most of the suns energy?
nuclear fusion
When fossil fuels are burned how is most of the energy released?
Fossil fuel molecules have energy in the form of chemical bonds holding the atoms together. When burning, some energy is used to break these bonds. Oxygen the combines with the atoms of the fuel forming bonds with less energy. The difference in the energy of the old bonds and the new bonds is released as both heat and light. Most of the energy is released as heat.
What is the most common energy used?
That released by fission in a nuclear reactor
Who recognised that large energy is released as a result of the fusion of hydrogen nuclei to form deuterium?
The most likely fusion reaction to be exploited is deuterium + tritium forming helium +a neutron, not what you have put in your question. The physics of this was worked out by Hans Bethe
Most of the energy in an isoctane reaction is released in the form of what?
During burning the energy is released by heat.
Most of the energy in an iso-octane reaction is released in what form or forms?
Heat and light (:
In a chemical reaction what does it take energy to do?
For most chemical reactions, energy is required to supply an "activation energy" required before reaction.
A chemical reaction that transfers energy from the reactants to the surroundings is reffered to as?
A chemical reaction that transfers energy from the reactants to the surroundings is referred to as an exothermic reaction. A reaction that takes energy in is endothermic.
What type of reaction supplies the most energy?
fusion nuclear reaction followed by fission nuclear reaction
Can energy be released during chemical reaction can it be absorbed can chemical reaction take place in which energy is neither absorbed or released?
The simple ANSWER IS yes!!! The reaction that does this is referred to as 'Exothermic'. Energy can be absorbed during a chemical reacton, but it needs an activation energy to start the reaction. For all chemical reactions there is always a change of energy. No reaction is ever 'energy less'. However, the exchange of energy can be very small. Example of an exothermic reaction is sulphuric acid and sodium hydroxide. if you hold the beaker the two reactants are in , it will feel warm. This is an exothertmic reaction. For the thermal decomposition of calcium carbonate, you have to heat it up; you are driving energy in, so it is an endothermic reaction. Other endo thermic reactions, may feel cold, they are absorbing heat at ambient room temperature.
In photosynthesis which process uses the most energy?
Energy is stored in light reaction in ATP.That energy is used in dark reaction
Do enzymes increase the activation energy of biochemical reactions?
Enzymes speed up a chemical reaction by lowering the energy required for a reaction to procede, the Activation Energy (Ea). The overall change in energy of the reaction is unchanged, so the net amount of energy released in a reaction is not increased.
What type of reaction produces most of our energy?
Respiration, which is a redox reaction. C6H12O6 + 6O2 --> 6H2O + 6CO2
Are exothermic reactions chemical?
Most chemical reactions are exothermic, that is, they release a certain amount of heat as a by-product of the reaction. Endothermic reactions, those which absorb heat, also do occur, but they are more rare. Endothermic reactions are driven by entropy only, whereas exothermic reactions are driven by the energy that is released. The more energy is released, the more easily the reaction will occur.
What factor will most likely lower the activation energy of a reaction?
The presence of a catalyst will lower a reaction's activation energy.
What reaction produces thermal energy?
The most common reaction producing heat is burning, in which fuel is combined with oxygen from the atmosphere to produce heat which is a form of thermal energy. The problem of using the heat in the most efficient way possible in engines leads to the science of Thermodynamics, a branch of physics.
