Key terms: Reset Stereoisomers that are not mirror images of each are ____________ . The chemical and physical properties of two
sergejj [24]

Answer:

Enantiomers/ Isomers/ Stereoisomers/ Meso compounds/ Constitutional isomers/ Diastereomers.

Explanation:

Isomers are molecules that have the same chemical formula but have different conformation, or in its connections, or the orientation in space. Isomers have different chemical and physical properties (second blank).

The isomers that only differ by the orientation of their atoms in space are called stereoisomers (third blank).

The stereoisomers that have a chiral carbon and do not mirror images of each are called enantiomers (first blank). They can deviate the polarized light.

When a compound has two or more chiral carbons but they compensate for the deviation of the light, and the compound is optically inactive, it's called a meso compound (fourth blank).

When the isomers differ in the way the atoms are connected it's called a constitutional isomer (fifth blank).

When the molecule has more than one chiral carbon, it will have pairs of enantiomers. The isomers that aren't of the same pair are nonsuperimposable mirror images of each other and are called diastereomers (last blank).

labwork [276]

Chemical because the first thing disappeared and changed into something completely different. Because you got something new from what you started with, it is chemical.

Idk why its pumpkin spice latte but I'm not going to judge. I prefer drinking bleach.
