dihydrogen monoxcide is everywhere! take cover!!!...but what is it really?
88222
Water. Water contains two hydrogens and one oxygen. It's technical name should be dihydrogen monoxide, but we knew about water before chemistry was officially developed.

Have you tested the levels of pollutants that bus or car is putting out?  How about the water you drink?  Or the mountains of waste produced by the office you work at?  How far away do you live from a chemical factory? Or a nuke plant?  Where is all the garbage going that you and your family produce?  How about the food colorings and additives?\n\nAnd you're worried about some cigarette smoke?\n\n\nPULLLLLEEEEEEEEESSSSSSSEE!!\n\nPeace.

I don't know, but I wouldn't want to be standing near it. I looked it up on the internet and here is what it said:\n\nNEVER MIX CHLORINE BLEACH AND AMMONIA! Together they release a toxic gas.\n\nIt says chlorine bleach but I would think it's the same with clorox.\n\nHeres another warning:\n\nDon’t mix with any other household cleaners – especially ammonia.\n\nAND Another\n\nWhat excellent idea to mix bleach (like Clorox) and ammonia (like Windex)! Let's just look into your future before you mix your first batch:\n\nAt first you will smile to yourself thinking "I wonder why no one has done this before! I must be the smartest person who ever cleaned anything!"\n\nThen you will marvel at how well your solution is working. It is so wonderful you are seeing white spots in your peripheral vision!\n\nAfter a bit of scrubbing you might think to yourself "I think I'll take a little break until this light-headed feeling wears off."\n\nYou will immediately wake up on a rolling bed on the way into an ambulance with a (hopefully) handsome EMT saying "It's a good thing you taught your children how to dial 911 - we arrived just in time." You will lose consciousness again.\n\nAt the Emergency Room (ER) they will stick a tube down your throat and tell you how dumb you are. When your husband gets there he will tell you how everyone knows you're not supposed to mix bleach and ammonia and you are dumb.\n\nWho could have known (without a basic chemistry class) that bleach and ammonia combined give off toxic deadly fumes? but next time you will know to wear a gas mask.

Not sure what you're asking here . . .\n\nAre you asking why Agent Orange has remained in the systems of people exposed?  If so, the answer is that the problem isn't the Agent Orange (a mixture of 2,4-D and 2,4,5-T herbicides), but the 2,3,7,8-TCDD contamination that was a byproduct of the reaction mechanism used to make the herbicides.  2,3,7,8-TCDD is a fat-soluble organochlorine that bio-accumulates and is not removed from the body through the normal waste-removal processes.

Sounds like an "urban legend" to me. Given that the normal usage requires that the product become airborne and therefore inhalable, I would highly doubt that there would be chemicals in such concentrations to be lethal.

There is no shortage of ephydrine,\nThe medical authourities,and pharmaceutical authorities have made it a little harder to buy over the counter, as people use it as an ingredient  when making speed.

actually yes..\nperoxide is an ingredient of whitening kits\nand is commercially used\nbut dnt use high concentrations, it can be damaging otherwise..

Do you know how many chemicals there are in a blade of grass, or even a fingernail?  Tons!  The NUMBER of chemicals doesn't make a substance evil and is basically irrelevant.

its a suppressant... it'll only surpress it. look into a vitamin supplement to take with dinner. watch your nightly diet... sugar, cafeine etc.

I have a serious feeling that you haven't given us all the info.\nIf you know the density of HCl you can get the first one.\nBut we don't have enough info to even begin to tell you the relevance of the NaOH.   More info, or concentrate on your own homework...

According to the MSDS cover sheet Thionin is a non-hazard, it doesn't affect your body look at this site for more info:\n\nhttp://physchem.ox.ac.uk/MSDS/TH/thionin.html

I sure hope this is just a paper exercise and is not going to be actually performed.  Sodium hydride will react very exothermically with water and is extremely hazardous.

I would say CH2O2 (I'm assuming you mean formic acid, not dioxirane), CH3CO2H, and water.  \n\n"Important" is a tough word here, as all of these compounds can participate in h-bonding to varying degreees, with water being the strongest and CH2F2 being the weakest.  That said, strong hydrogen bonding gives rise to many of the nifty properties of water and in all three cases the h-bonding is powerful enough to raise the boiling points to be significantly higher than what you would expect based on molecular weight.

It is a preservative enhancer and Im thinking that no its not organic or natural. Most preservativs are not.\n\nThis is from:http://www.happi.com/current/May033.htm\nAnd the way the are talking they dont sound responsible. "the world is becoming increasingly obsessed with formaldehyde free preservatives"/ Hmm, gee I wonder why? Silly world...lol. Its called the preservative market update. You may find it interesting.\n\n(see near eye on page)\n"For more difficult-to preserve systems, SensivaSC 50 (ethylhexylglycerin) has proven to be an effective preservative enhancer. It is also globally approved (including Japan) and boosts the activity of preservatives in formulas that require a little extra strength."\n\nApparently Japan is much more vigilant about what preservatives they allow.

Inhaling bleach and ammonia mixture could case death. Checking on the symptons now...\nmostly respiratory since the two combined form a new chemical vapor that causes corrosion and damaged cells in the lungs
