Certain drugs will cause the pupils to dilate while other drugs cause constriction of the pupils. Certain drugs cause constriction of the pupils, such as alcohol. Other drugs, such as psychedelics, cause pupil dilation.Another term for the constriction of the pupil is miosis.Substances that cause miosis are described as miotic. The pupil opens wide when dark and small when light.est Answer: When bright light is shone on the eye, it will automatically constrict. This is the pupillary reflex, which is an important test of brainstem function. Furthermore, the pupil will dilate if a person sees an object of interest Looking at a personâs eyes is one of the first telltale signs of drug use.
a mole is the amount of pure substance containing the same number of chemical units as there are atoms in exactly 12 grams of carbon 12 i e 6 023 x 10 23 this involves the acceptance of two dictates the scale of atomic masses and the magnitude of the gram mole is the amount of pure substance containing the same number of chemical units as there are atoms in exactly 12 grams of carbon 12 i e 6 023 x 10 23 this involves the acceptance of two dictates the scale of atomic masses and the magnitude of the gram
A mole is the quantity of anything that has the same number of particles found in 12.000 grams of carbon-12. That number of particles is Avogadro's Number, which is roughly 6.02x10 23. A mole of carbon atoms is 6.02x10 23 carbon atoms. A mole of chemistry teachers is 6.02x10 23 chemistry teachers. It's a lot easier to write the word 'mole' than to write '6.02x10 23 ' anytime you want to refer to a large number of things! Basically, that's why this particular unit was invented.
