Answer:Chromatography technique that uses paper sheets or strips as the adsorbent being the stationary phase through which a solution is made to pass is called paper chromatography. It is an inexpensive method of separating dissolved chemical substances by their different migration rates across the sheets of paper.
You're welcome :)
They both have types of waves to function, that makes them related. Ways they are different is one can travel in space, the other one cant.
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).
Answer:
1:1
Explanation:
The ratio of metal cationic atom to non-metal anionic atom in the compound is 1:1.
This is an ionic compound.
- This is because metal cationic atom has two valence electrons.
- Non-metal anionic oxygen has six valence electrons
- Calcium loses two of its valence electrons to be isoelectronic with Ar and this confers a stable configuration to it.
- Non-metal oxygen atom accepts the electrons and adds 2 to its 6 electrons to become isoelectronic with neon.
- So, 1 metal cationic atom combines with 1 non-metal anionic atom to form the compound.
