I have a question about Optics and how this links to burning fuels in a combustion reaction.
If I have hexane, the following reaction occurs:
hexane + oxygen $\rightarrow$ carbon dioxide + water vapour
Now, I have a question. Why don't we tend to see any water being formed when we burn methane on a gas cooker?
This is only because the same equation can also be applied to methane in our cookers:
methane + oxygen $\rightarrow$ carbon dioxide + water vapour
I tried this earlier while preparing my food and it turns out I don't see any, even though I am burning the fuel.
