2C8H18 + 17O2 --> 16CO + 18H2O

C8H18 + 8.5O2 --> 8CO + 9H2O

half equation, halfs can be used in combustion.

Is this chemical equation considered a combustion reaction and if yes why 4Na plus O2 equals 2NaO2?

4Na+O2=2Na2O? That must be the equation... Im not sure what you're asking... But, in a combustion reaction, something reacts with oxygen gas (O2). In this equation sodium is reacting with oxygen... So, yes, this is a combustion reaction.


Is this equation exothermic or endothermic C3H8g 5Og ----3CO2g 4H2Og 2220kJ?

This equation is exothermic. The energy is written in positive numerals on the right hand side. This means that energy has been released. Moreover, this is a combustion reaction.


Is Octane is seven carbon linear alkane?

No. Octane is an alkane but it has eight carbons.


What causes the Bunsen burner sometimes have a blue flame and sometimes an orange flame?

The blue flame is observable when complete combustion occurs, which is when the air valve is opened enough to allow the ideal amount of oxygen. The orange flame is due to the burning of carbon particles (soot) caused by incomplete combustion, which is an effect of too little oxygen available for the reaction.


Why does octane have a higher boiling point then water?

Octane is a straight chain molecule with a large surface area and stacks easily with other octane molecules. This increases the strength of the London dispersion forces that keep the octane molecules attracted to each other. The London dispersion forces on octane are greater than for smaller straight chain molecules because octane is both heavier and has more electrons that make it more polarizable.
