Cyanide can give off a bitter almond smell, but doesn't always give off an odor, and not everyone can detect this odor.
Yes. My friend had a little dog that had seizures. Just before abd just after a seizure he gave off an odor.
NO, They do not stink or put off an odor.
Isopropyl alcohol does, indeed, give off a fairly strong odor as it evaporates... but airing the place out would rectify this. The odor would be gone fairly quickly as isopropanol evaporates pretty fast. This odor isn't like nail polish remover, which is primarily acetone.
Yes,there is. We studied cockroaces in Madeira today in my class.When they are threatened they give off a smelly odor.
This isn't like the movie predators.
The meat, which is a pale pink colour when good, turns brown, may give off an off-odor. It will also sometimes get a bit sticky to the touch.
Some gases have no odor. Air and its normal constituents are odorless. Since smell, odor, is sensed from gases, any liquid or gas that does not give off any gas will be odorless as well.
Usually, the smell will give it away. It develops an off-odor similar to mercaptan. A greenish tinge, sliminess and off odors mean it is past its prime.
Clothing is made of various 'fabrics', which are porous materials that can absorb or adsorb body fluids such as perspiration, blood and urine. Over time, those fluids deteriorate when exposed to air, and give off an odor. Clothing can also gain an 'odor' from being dry cleaned with a chemical called 'perk', which reacts with perfumes and deodorants to create an odor that is unpleasant.
