When studying the effect (efficacy) of a medication, researchers will give some subjects doses of the medication under study and others an inactive or inert doses to see the relative effect of the medication.
This known as a 'blind study' because the participants do not know know whether they received the medication or the inert dose.
A 'double blind study' is when a third party designs the experiment and prepares the doses so that neither the subject or the scientist doing the testing knows which is getting the live dose.
Placebos
These are called "Placebo".
Inert means they don't react. Group 18, the noble gases, are inert.
inert gas inert gas inert gas
no oxygen is not a inert gas
Gold is active, or at least not inert. Only the noble gases are inert.
The inert gas had no effect on the experiment. The bomb was inert and failed to explode.
argon is an inert gas
Carbon monoxide is not an inert gas.
group 18 elements. they are inert because they have completely filled orbitals and and stable or chemically inert.
Helium is an inert gas, and seldom reacts with other elements. After the explosion, they discovered the inert bodies of the two guards. The inert Lunar Rover is still parked at the landing site of Apollo 17, awaiting a new battery and a new driver.
Inert is a state of doing little to nothing. In relation to metals, an inert metal is a metal that is not reactive. Gold can react with other things so it is not inert.
