I need to decrease the viscosity of B-99.9 biodiesel with common alcohols/surfactants. I’ve tried isopropyl rubbing alcohol, and it works well. Everything else, however has too high of a water content to mix with the fuel.

Both are useful. Oxygen for breathing and for increasing ozone layer. Hydrogen to use as a pollution free fuel.

I know that water smothers the flames, but it has free oxygen in it, which is why fish can breathe water. This is different from what I am calling bonded oxygen. I checked around for the answer to this, but it was talking about the bonded oxygen atoms in a water molecule.

I hypothesized that the evaporative cooling effect of water would reduce a fuel’s temperature to below ignition temperature. But then I considered the case of throwing liquid oxygen on a bonfire. This would be extremely cold and evaporate very quickly, which would result in rapid heat loss. Yet I common sense tells me there would be a huge combustion.
Cheesus, let me clarify. I am asking why the FREE oxygen in water does not combust with wood.

Free oxygen is dissolved in the water, not bonded.

I know that water is not the answer for sure since it has no carbon..
I dont know about this question, plz help!

A chemical engineer studying the properties of fuels placed in 1.500 g of a hydrocarbon in the bomb of a calorimeter, and filled it with O2 gas. The bomb was immersed in 2.500 L of water and the reaction initiated. The water temperature rose from 20.00 C to 23.55 C. If the calotimeter (excluding the water) had a heat capacity of 403 J/K, What is the heat of combustion (qv) per gram of the fuel?
