Dihydrogen oxide is colorless, odorless and can kill you. Anyone know what it is?

My high school chemistry teacher made sure we were all warned about this dangerous chemical.\n\nH20. Water.

DON'T KNOW BABY  but this question just contributed 2 point closer to me getting to level 3.  and does anyone care???  probably not as much about farts.  but just like your tooty, thought i'd share that (worthless info) with the rest of the yahoo bloggers out there.  LOL  just being silly with you.  hope you don't mind.  but it is a funny, silly question.  actually i loved it!!!!!   what an imagination.  farts and the ozone.  well farts can be deadly in a closed room (so i've heard) so you may be on to something.

any sort of oxidizer, sugar by itself will "burn", but as you may have learned it isnt complete combustion without a large amount of extra o2 being present.  could have been a permanganate (barium permanganate, magnesium permanganate), however if you hope to acquire some of this yourself, it might be a little hard to come by.  you could always use nitrous oxide too :) N20

Ethanol. with a coloring in it. Red or Blue usually.\n Hey all of you who are saying "mercury".....If you have a mercury thermometer in your home dispose of it quickly and safely! Even a small Mercury spill must be reported quickly as it can poison hundreds of people! It is considered as hazmat situation!! Contact with even tiny amounts of mercury can cause brain damage, birth defects and death. Mercury has no place in the home.

What three pure elements become deadly when placed one way but meaningless when mixed together?

Basic. Metal oxides are classed as basic anhydrides, because they react with water to form bases:\n2K2O + H2O ===> 2KOH;  MgO + H2O ===> Mg(OH)2\nNonmetal oxides like CO2, NO2, SO2 are acid anhydrides.

Dihydrogen monoxide, otherwise known as water, is vital to green vegetation. Just think about the name for one second all you people who didn't get the connection between the name and what it is.

It is a heavy, COLORLESS gas with an odor like a struck match. It is toxic and unprotected proximity to it may cause serious harm to health and or death. This gas combines easily with water vapor, forming aerosols of sulfurous acid (H2SO3), a colorless, mildly corrosive liquid. This liquid may then combine with oxygen in the air, forming the even more irritating and corrosive sulfuric acid (H2SO4).

First off... dihydrogen monoxide is ....WATER!!!!!!!!!\n\nThe smaller the salt crystals you are trying to dissolve, the more rapidly they will dissolve... due to increased surface area.

Carbon oxide can be bad for lungs, can cause dizzines, and unconsciousness.\n\n...

Di-hydrogen oxide would be the chemical name of water. H2O is the chemical formula. The are many ways a person could draw a physical model of it. Now there are other chemicals and ions that only contain hydrogen and oxygen. There is Hydrogen peroxide as an example of a chemical. There are hydroxide ions HO- and oxonium ions H3O+. There is a limit to how many chemicals can be derived by both Hydrogen and oxygen because Hydrogen can only bond to one atom at a time, and Oxygen can only bond to two atoms at a time. Although that would in theory allow an oxygen chain that could have a hydrogen atom on each end with the exception of hydrogen peroxide H2O2, this does not occur. Species with only oxygen. An oxygen atom O it seldom ever found in nature for electronic reasons. An oxygen diatomic molecule O2 is the most abundant form of pure oxygen in the atmosphere. Ozone O3 is not particularly stable it is usually made by free radical chain reaction, but then tries to react with whatever it can. H atomic Hydrogen seldom ever found in nature. Diatomic hydrogen molecule H2 is the most abundant species in the universe, but somewhat rare on earth. Hydrogen H+ ion can exist, but in water it is the short hand for writing H3O+ which I referred to earlier.

The easiest way to find out the answer to that question is to look up the MSDS.  It gives all the information you need about it's toxicity, reactivity, etc.  A lot of chemical supply companies have MSDS on their websites, and I think there might be a government website that has MSDS accessible online, but I'm not sure.

Well the obvious one about explosions and fires.\n\nThen you have that some of the propellants used can be pretty nasty to handle.  Liquid Oxygen, Liquid Hydrogen, etc are very cold and if you spill on yourself you won't live very long.  Liquid Oxygen (along with pretty much any other oxidizer) will allow things to burn very well.\n\nThe hypergolics are the really nasty ones though.  They tend to be toxic and if you mix them they burn (which is why they're called hypergolic and is an advantage in many cases) and some of them are known carcinogens.

i think its hydroggen gas burning

Yeah, you can use H2S gas... Hydrogen Sulphid. With just100 parts H2S per a Million parts of Air, it will knock you out in less than a 2 seconds, stop your respiratory functions as it paralyzes your nervous system. It’s made by combining Hydrogen and Sulphur Gases together. \nWell, seeing it comes from crude oil, it is relatively easy to find and make.\nOne short note; if you do not get the person into a breathable atmosphere within 4 minutes and revive them, they will die.
