Answer:
i
Explanation:
b. magnetic centers
c. domains
d. poles
Answer:
The correct answer is c. domains
Explanation:
In terms of Chemistry, there is a concept called the electron domain and it has to do with the number of lone pairs or bond locations that are located around a particular atom in a molecule. The electron domains are also called the electron groups.
Fe³⁺ +e⁻ -> Fe²⁺ is the half reaction equation represents the reduction of an iron(II) ion
When an element or a compound gain electron , decreasing its oxidation number is called reduced and the half cell reaction is called Reduction reaction.
Fe³⁺ +e⁻ -> Fe²⁺ , Option C
In this reaction the Iron is gaining electron and the charge is getting reduced from +3 to +2 .
Therefore this half reaction equation represents the reduction of an iron(II) ion.

Thelimitations of forensic drug chemistry is (1) they cannot create drugs out ofwht they learned in chemistry although they can create one, (2) theire line of expertiseis limited to the illegal drugs and crime committed acts.
They know how to identify the drugs found at crime scenes.
-solid sulfur
-solid calcium
-gold
Answer: Option (a) is the correct answer.
Explanation:
Amorphous means without any crystalline structure or definite shape. Whereas a solid whose atoms are not bonded together in a definite lattice pattern. This solid is non-crystalline in nature.
For example, glass, gel, plastic etc are all amorphous solids.
Whereas solid sulfur, solid calcium, and gold have a definite lattice pattern and has a crystalline structure. Thus, they are not amorphous solids.
Thus, we can conclude that out of the given options glass is most likely to be amorphous.
