Why oxygen is not explosive?
Oxygen in and of itself is not flammable. Rather it supports the combustion of flammable materials.
For the TEMPORARY transport of portable medical oxygen containers it is permitted. However (in the US) bottled Oxygen is considered an explosive danger (oxygen itself is not explosive but exposed to flame the rapid accelerant nature of oxygen is an explosive reaction). It would be foohardy at best and reckless at worst to make this a regular practice.
Any fire or explosive need oxygen to burn but with explosives the oxygen is in the molecule and it reacts with itself. Fuels need external oxygen to cause a explosion. The chemical reaction varies depending on what compound were used to prepare the explosive normally a nitrate (NO, providing the oxygen) and carbon (C, as the fuel).
Why doesn't oxygen in an oxyacetylene torch burn without the acetylene yet medical oxygen is explosive?
Oxygen is not actually explosive. In an acetylene torch, the torch burns the acetylene and the oxygen only facilitates combustion, so it is not burning the oxygen. Hospitals warn of the explosion hazard of oxygen because pure oxygen accelerates the burn of fuel so fast that it is like an explosion. In common air there is roughly 79% nitrogen and 21% oxygen, all fuels must have oxygen to burn and when pure oxygen is introduced…
liquid oxygen is in effect more explosive than tnt, but by means they are different. liquid oxygen is not explosive at all without the other chemicals, where all tnt needs is heat, making tnt easier to use. also, one must the fact that tnt is more practical in that it is easier to come by. so, if you put the same effort into aquiring them both, you would end up with enough tnt to make…
In general gasoline is not more explosive then gas although it depends on the conditions and the gas. Probably you are referring to natural gas, the gas piped into homes which is predominantly methane. In general flammable gasses are more explosive than flammable liquids because they are mixed up with atmospheric oxygen. This is why modern cars have fuel injection which sprays the petrol to make it more easily combustible. In fact liquid petrol is…
Of the elemental gases and under normal conditions, hydrogen is explosive in the presence of air or oxygen. Under normal conditions there are a large number of inorganic and organic compounds that are explosive gases. Methane, CH4, is explosive in the same way hydrogen is, and so it ethane, propane, butane, .... Gases that are explosive in and of themselves are the various compounds of Nitrogen: NO NO2 N2O2
Simple... As an explosion consists of three things, just like a fire, you would need all three: Ignitor, as in the energy to start the explosion, or often referred to as temperature needed to start the combustion Fuel, the explosive itself, Oxygen , no oxygen, no explosive or fire... As the explosives and oxygen are present, the temperature isn't . If you were to heat up the explosives during transport high enough, they would explode.
No. Oxygen itself is not flammable, but it is necessary for fire. Fire is a chemical reaction between oxygen and a flammable substance. Fire is possible on Earth because ordinary air is 21% oxygen. Pure oxygen is considered a fire hazard because higher concentrations of oxygen will make it easier for a fire to ignite and will allow it to burn hotter and faster than normal.
If the flour is extremely finely ground, the particles can behave almost like a fog or a gas, and reactions with oxygen molecules can be extremely efficient and fast (i.e. explosive), because the oxygen does not have to "burn" through the outer layers of the particles. The phenomenon is not restricted to flour. The right sort of dust (e.g. fine coal dust) can be highly explosive.
