Spontaneous Combustion would be which DOT hazard class?
The DOT classification for Spontaneously Combustible material is Division 4.2
Spontaneous is a word that would be replaced by "random" today. It means to be "fresh", "off the wall", and rather joyful. It can also mean "instantaneous." "Ellen and Elizabeth fell into a spontaneous conversation about boys." "Spontaneous combustion is always a danger with heat and petroleum products." "Jane has a knack for finding spontaneous fun."
You ask this as if all forms of incomplete combustion would be described by the same equation; different fuels have different equations for either complete or incomplete combustion. I will add that it would be characteristic of many forms of incomplete combustion that one of the combustion products is carbon monoxide. CH4 + 3O2----> Co2 + 2H2o+ Co
spontaneous reproduction is when out of no where, something is reproduced. many, many, years ago, people didn't have refrigerators to keep their food fresh. so their meat and other foods would spoil and so there would be magots and other insects crawling in their food. their explanation would be spontaneous reproduction.(they thought dead meat could reproduce living organisms)
If a golfer's ball is in a hazard and he encounters an animal and fears for his safety does he get free relief?
The complete combustion of methane would yield carbon dioxide and water as the only products of combustion, therefore incomplete combustion would included any other product or byproduct. This usually occurs when there is not enough oxygen present to allow for complete combustion, which can then yield the formation of carbon monoxide and soot (elemental carbon). Also, because air is almost 80% nitrogen, incomplete combustion of methane can also produce nitrogen oxides.
A lateral hazard is simply one where it runs alongside the hole of play, but does not actually cross it. It is also deemed by the committee of the competition/course or tournament that it is impossible/ impractical to drop behind the line of the hazard (which you would normally do with a normal water hazard).
An internal combustion engine is an engine where the fuel combustion happens inside a combustion chamber. There are both Reciprocating and Rotary engines that fall into this category. Most cars on the road today use internal combustion engines. An example would be the V-8 Hemi engines that Dodge puts in their trucks.
How would you differentiate the effect of physical hazard from biological hazard and chemical hazard?
The closest to a non-polluting gas would be hydrogen as the principle combustion product would be water. ANy flammable gas with carbon, sulfur or nitrogen would produce contaminants. The gas would have to be combusted in a low temperature environment like a fuel cell to avoid the formation of nitrogen oxides in the combustion chamber. If a high temperature system (internal combustion engine) is considered the combustion air would have to be nitrogen free…
