No, coal is almost pure carbon.Brock said:are you sure that's what's causing most of the explosion though, because there are also H Atoms in Coal and when that burns it will combine with O.
http://en.wikipedia.org/wiki/Energy_value_of_coalCoal consists primarily of carbon, but this is usually mixed with various impurities, including water and mineral matter such as sand and clay. The relative amounts of these impurities affects the usefulness of the coal as a fuel.
Huh? Sorry, but those words don't form a coherent thought. A lot of them don't belong in the same sentence with each other.Also when pure H and O are burned it's interesting to note that they have an implosion effect, for instance you can weld wood to metal with this flame, and it will reduce radiation in a material.
Yes, steam is less dense than hydrogen gas. I'm not sure if cooling of the steam has to occur before it's less dense.Brock said:when pure H and O are burned it's interesting to note that they have an implosion effect.
A small percentage. Note that most of the hydrogen in coal is already tied up in water - it is already burned.Brock said:@ russ
I looked at the diagram on this page and that looks like plenty of H to cause a percentage of the burn.
Don't call the separation of H2 into 2 H an explosion. There is no energy released.H2 and O2 would explode to HH and OO before forming the water molecule
As Jeff said, that would only be true if the temperature remained the same and it doesn't. If it were true, hydrogen wouldn't make such an excellent rocket fuel.H2O which would take up less space then what it was before, so there's probably imposion, after the explosion.
I've never heard the claim and don't know the basis, so I can't evaluate it except in the context of the other claims you are airing here...People that make welders out of H2 and O2 (and not in the books/proven HHO) say it can weld wood to metal.
That's just crackpottery.here's a video of the radiation reduction of the gas, I just don't know why they would make the video if their equipment didn't read what they say it does.
Yes, the most common fuels we use are hydrocarbons, which get their energy from the combustion of hydrogen and carbon in oxygen. Your original question was asking if hydrogen is the only thing that burns and the answer is a simple no.there's alos plenty of H in fuels, when that H is in an explosion it must go somewhere, right?

I'm sorry, but that's just pure crackpottery. It is nonsense and we don't entertain discussions of such things here - it detracts from our mission of teaching science. Please be advised that we will not continue with discussion of that.Brock said:well here's the video that explains the implosion effect. sorry that it's bad quality.
33.3% H and 66.6% O = implosion
I do some experimenting with this gas myself, and follow many others experiments, I see signs of implosion in some bubbles I explode, bits of water blowing out the centre.
I mentioned hydrogen gas. A typical rocket uses liquified hydrogen (and liquified oxygen), which is much denser than the steam produced from combustion. Liquified hydrogen / oxygen provide more energy per pound of fuel than any other combination I'm aware of.russ_watters said:hydrogen ... an excellent rocket fuel.jeff reid said:steam is denser than hydrogen gas

Elements that are highly reactive and have a tendency to release large amounts of energy quickly are most likely to cause explosions and burns. These include elements such as hydrogen, oxygen, and nitrogen, as well as some metals like sodium and potassium.
These elements have a strong tendency to react with other elements or compounds, often resulting in the release of heat, light, and gases. This rapid release of energy can cause explosions and burns.
Yes, explosions and burns can be prevented by handling these elements with caution and following proper safety protocols. This may include storing them in a controlled environment, using protective gear, and avoiding any potential sources of ignition.
If you come in contact with an element that causes explosions and burns, it is important to seek medical attention immediately. In the case of a chemical burn, you should also rinse the affected area with water for at least 20 minutes.
Yes, factors such as temperature and concentration can also play a role in the likelihood and severity of explosions and burns caused by these elements. Higher temperatures and higher concentrations of reactive elements can increase the risk of an explosion or burn occurring.
