Violet
brown color fumes
Colorless , but exposure to moist air gives white fumes.
It "fumes" aka vaporizes. This is used for finger printing mainly, known colloquially as the "finger print method".
Iodine crystals and concentrated ammonium hydroxide solution.3I2+4NH4OH = NI3+3NH4I+4H2OAmmonium iodide is filtered out and the precipitate on the filter paper is put in a ammonium hydroxide solution. Take out and dry before detonation.SAFTEY!!The Whole Production MUST BE DONE UNDER A FUME HOOD!! THE FUMES FROM THIS PROCESS ARE FATAL!!Do NOT GET NITROGEN TRIIODIDE ON YOUR CLOTHES IT STAINS ANYTHING IT TOUCHES.WEAR EARPLUGS WHEN DETONATING THE TRIIODIDE AND KEEP A FAIR DISTANCE! SHRAPNEL FLIES!!
exhaust fumes of a car
first off DO NOT HEAT IODINE CRYSTALS because they create the same sort of fumes you would fine in a meth lab and it is possible that it can kill you because of its extremely toxic fumes and
brown color fumes
When it is iodine (I2) it is only physical sublimation of the black (metallic shiny) I2 crystals into purple heavy gas clouds or fumes
No, aluminum does not give off any toxic fumes that are harmful in anyway. It does not produce gases nor does it vaporize.
Yes.
No. Sublimative substances (wow thats a mouthful!) are solids that when heated do not form a liquid but instead vaporise. Ammonium hydroxide cannot be isolated as a solid. It only exists in aqueous solution. An example of a solid that sublimes is Iodine which when heated gently in a test tube produces purple fumes and the dpoits as solid iodine on the cooler sides of the test tube above the heat. If you want a more technical description of sublimation look up sublimation (pahse transition) in Wikipedia
Definitely not! Galvanized when heated will emit toxic fumes.
Breather is provided where the oil tends to give out fumes after getting heated. in a fluid coupling the fluid is not heated upto that temperature hence not required
It will melt and stick to your skin. (and burn like crazy) (also the fumes)
Possibly, but the fumes are usually only harmful when heated.
stainless steel contains chromium. chromium gives off toxic fumes when heated.
Solids do not evaporate, they Sublimate, i.e. they go directly from the solid state to a vapor. An example this process would be if you gently heat Iodine crystals, you will see purplish vapors begin to form ... it's sublimating.CAUTIONIf you try this, do it only in fume hood and with a very small sample of Iodine. The fumes are poisonous!
