Small, non-polar molecules do not bind to your olfactory receptors because they have no partial charges.
That most are left handed-
If you're talking about what I think you're talking about, the fact that it is not "scientifically valid" might have a lot to do with it.
scientifically the evidence didn't match.
Potentially, it depends what the opinion is. For example if my opinion was that cheese floats then that can be scientifically tested.
No
Odor absorbers work by chemically trapping or neutralizing odor molecules in the air. They contain substances that can bind to odorous compounds, preventing them from reaching our noses and creating a foul smell. This process effectively reduces the concentration of odor molecules in the air, making the smell less noticeable or completely eliminating it.
This is ethanol (C2H5OH) with some added substances to modify the color, odor and taste.
Objects that exist, scientifically are substances.
Promethium is a radioactive element and does not have a characteristic odor on its own. Any odor associated with promethium would likely be from compounds or substances it is combined with in a laboratory setting.
After making sure they are not dangerous, by smelling them.
It is called excretion, scientifically.
Pure platinum does not have a distinct odor. However, when combined with other substances, the resulting compound may have a smell.
Sodium itself does not have a distinct odor. However, when sodium reacts with certain substances, it can produce compounds that may have odors.
Yes, odor is a property of matter. It is caused by volatile molecules that are released from substances and detected by our smell receptors. Different substances release different molecules, resulting in the wide range of odors we can detect.
No the opposite. It is a characteristic of metals that they have very little or no odor.
No they,are not some are tested on but they are not scientifically createx
AnswerNeither. Odor is not a change at all. Odor is airborne molecules that have a particular smell. A change is a process and odor is not a process. The things which cause odors can be either physical or chemical. For instance, the body odor is caused by chemical changes, but if you open jar of a smelly chemical, that is a physical change (some of the molecules of the chemical are evaporating and are thus airborne).When talking about mixing chemicals and substances, a change in odor is a chemical change.(I assume this is what you meant when you asked is odor a chemical or physical change)
