Temp. for 1 mole of CO2 with 15 L of volume at 98.25 kPa.
Reactants:
C8H18 is molecular because carbon and hydrogen are both nonmetals. This is also a non-polar bond. This is not soluble in water.
Products:
CO2 is molecular because carbon and oxygen are both nonmetals. This is also a non-polar bond. This is soluble in water.
H2O is molecular because hydrogen and oxygen are both nonmetals. This a polar molecule. This is soluble in water.
Mass of each reactant needed to give 1 gram to every student / Molarity of solution
When any hydrocarbon undergoes complete combustion, it is converted to CO2 and water vapor.
This process is a combination of "oxidation" and "reduction".
All combustion reactions are "redox" reactions in which the carbon is "oxidized" and the oxygen is "reduced".
C8H18 + O2 --> CO2 + H2O
-18 +18 0 +4 -4 +2 -2

In the early 1900's chemists learned that they could control pre-ignition easily and inexpensively by adding "tetraethyl lead"
For more than 50 years, tetraethyl lead was added to give gasoline more resistance to self-ignition.
Octane inherently has this characteristic but because it comes out later in the crude oil distillation process, it's more expensive.
Octane is now added instead of lead.

O2:
The combustion of octane primarily occurs in the combustion engine.
Octane is a component of gasoline.
Combustion of octane produces a large amount of power for its size, which have been put into machines ranging in all sizes.
This creation has advanced the human race forward and has shaped the world to how we know it today.
H2O:
CO2:
C8H18 + O2 --> CO2 + H2O
a. Octane + Oxygen --> Carbon Dioxide + Water
b. 2C8H18 + 25O2 --> 16CO2 + 18H2O
c. Octane(l) + Oxygen(g) --> Carbon Dioxide(g) + Water(g)
d. This is an exothermic reaction because heat and energy is being released.
e. There are no catalysts in this reaction.
C8H18 + O2 --> CO2 + H2O
This is a combustion reaction because O2 is a reactant.
Octane(l) + Oxygen(g) --> Carbon Dioxide(g) + Water(g)
Oxygen, Carbon Dioxide and Water in this reaction are all gases.
This means that the particles have high entropy, with high amount of kinetic energy. The particles are also very spread out.
Octane (C8H18) in this reaction is a liquid.
This means that the particles have medium entropy and kinetic energy. The particles are not as spread out as the gases.
