Btw you could have had any combination as long as the "O2" on the left was less than 12.5 and CO was produced on the right, and the entire equation was balanced
+ for anyone else in this discussion about incomplete combustion
Here's a past paper for GCSE C1 (I think it was that) where they ask you to balance an equation for incomplete combustion with only CO and water as products
I mean the bit in smaller text, not in the orange box

i have no idea what you are going on about. You are talking down to people like they have no idea. They will accept red because it does turn slightly acidic FACT
Since it is causing so much controversy between two people, imagine it across the whole population; they should accept both orange and red since personally I think the question wasn't completely clear
They probably didn't realise there were fewer moles of aluminium than electrons and just did 20 x 27 = 540. I think someone I was talking to after the exam said she didn't know how to do it so guessed the method and got that.
If i times it by 3 instead of dividing it by 3, how many marks do you reckon i would get, if any?
Anyone that put just CO2 and H2O got it wrong - the picture taken in the CGP is COMPLETE combustion - this asked for INCOMPLETE COMBUSTION. Aditionally red would be acceptable as I reviewed this w/ my teacher.
I got C8H18 + 8.5O2 -> 8CO + 9H20 (my friends agreed but we could be wrong) I think yours might also be correct, as it's the example given in the CGP revision guide, although I don't think it said anything about producing carbon in the question.
Thank god, people got this. I got exactly this but was questioning myself due to the 8.5, but it balanced out. Also i remember doing a 1c past paper and that had nothing to do with carbon and carbon dioxide , hence i didnt go the cgp route
