What are the reactants of burning gasoline?
2C8H18 + 25 O2 → 16CO2 + 18 H2O + energy so the reactants are octane (actually there are other hydrocarbons present too) and oxygen.
Is burning octane exothermic or endothermic?
EXOTHERMIC
How many moles of H2O are produced when 0.468 mol of octane is burned?
It forms H2O when burned.There are 3.744 moles of H2O after burned.
How many moles of water can be produced by burning 325g of octane in excess oxygen?
Balanced equation: 2C8H18 + 25O2 ==> 16CO2 + 18H2Omoles of octane used: 325 g x 1 mole/114g = 2.85 moles octanemoles H2O produced: 18 moles H2O/2 moles C8H18 x 2.85 moles C8H18 = 25.65 moles H2O
How many moles of H2O are produced when 0.721mol of octane is burned?
6,49 moles of water are obtained.
Word equation for the reaction for the burning of octane in air?
octane + oxygen --> water + carbon dioxide

What is a use for octane?
Octane is one of the alkane group of hydrocarbons and is a major component of petrol (gasoline). Burning octane gives this chemical reaction: 2.C8H18 + 25.O2 = 16.CO2 + 18.H2O The formula shows that 1 kg of octane burns with 3.51 kg oxygen to produce 3.09 kg carbon dioxide and 1.42 kg water.

Can you run high octaine fuel?
It depends on the type of engine and how high of octane you are running. Octane slows the burning of fuel, so if it is too high of octane for the engine, you will end up burning out your exhaust valves because burning fuel is being pushed out of them. 92 or 93 octane that is available at fuel pumps as "premium" fuel is ok for most engines. I wouldn't run anything over about 100 octane.
What is a physical change melting ice or burning paper or rusting iron or burning gasoline?
Meting ice: you start with H2O and finish with H2O
How many moles of H2O are produced when 0.721mol of octane is burned?
6,49 moles of water are obtained.
Is octane an element a compound a mixture or not matter?
Octane is a compound. octane + O2 = CO2 + H2O + Energy, You can tell by the inputs and outputs. Octane and Oxygen inputs and Carbon dioxide and water outputs, means Octane must consist of hydrogen H and carbon C, thus a compound not an element.
What does octane mean?
Octane rating is the resistance to burning. For example (not real number) a gas with an octane rating of 50 will burn at 100 degrees Fahrenheit whereas a gas with an octane rating of 100 will burn at 200 degrees Fahrenheit. Higher the octane number the harder it is to burn.
What is the combustion of C8H18?
Combustion of Octane: 2 C8H18 + 17 O2 --> 16 CO2 + 9 H2O
