SmokeyBrown · Answer

The first reaction, the Hydrogen reaction, produces mainly water as a waste product, which is not harmful to the environment.
The second reaction, which uses Octane, produces Carbon Dioxide as a waste product. The amount of Carbon Dioxide produced also seems to be quite high.
The third reaction, which uses Methane, also produces Carbon Dioxide, but seems to produce far less than the Octane reaction, based on the equation.

So, out of these three, which reaction would you say is the "cleanest burning" and which would be the most "environmentally damaging"?

karremat · Answer

hydrogen reaction - cleanest burning
octane is the environmental damage
