2C4H9OH + 11.75O2---->8CO2 + 9.5 H2O


Anyways Thanks A@di, Vin n Kimo :D

Ivo:
Right, my major(est) doubt so far.  Cropped up in many papers before, but for one example, w02, Q2) c) ii).  I don't understand any of the concentration, temperature stuff and sketching graphs.  Cos everytime they have a different y-axis, and sometimes they say same volume of oxygen level, sometimes it doubles.  Can someone please explain a general rule.

Many thanks in advance; I'm sweating over this!  :o

Q 7-a (i)
In the MS it's written "an equation that gives: alkene + alkane or alkene + alkene + hydrogen"

Why is that. Cracking of alkanes --> alkene + hydrogen not alkene + alkane

--- End quote ---
crackin of alkanes can be also used to produce hydrogen

Lariemeeva:
^Trust me. I know that very well. That's not my question. Why is it alkene + alkane + hydrogen
