Complete combustion of 2-methyloctane, C9H20, gives two products. Write a balanced equation, with state symbols, to represent the complete combustion of 2- methyloctane.
What is the state symbol and answer?
What is the state symbol and answer?
State symbol is usually liquid (I believe)
C9H20(l) + 14O2(g) —-> 9CO2(g) + 10H2O(l)

When you burn a hydrocarbon completely, you always form carbon dioxide and water vapour.
Do you know the formulae and physical states of carbon dioxide and water vapour?

I see. I was trying to avoid giving an answer, but fair enough.
I suppose water is a difficult one as it is a liquid in the standard enthalpy change of combustion and at room temperature.

I know it is too late, but notice for the next time that a combustion means to react with the oxygen in the air and that goes for both the C-atoms and the H-atoms in a general alkane. Because alkanes are nothing more than hydrocarbons, so bonds between H- and C-atoms.
And if you don't know what balancing equations means: the number of atoms - also the ones in a molecule - have to be the same on both sides of the chemical equations - for each atom!
State of symbol means just to write the letter in brackets for the proper aggregate phase (l is liquid, g is gaseous and s is solid).
