The molecule with same molecular formula but different arrangement of atoms is said to be an isomer.
When 2,2-dimethylbutane reacts with chlorine in the presence of light gives three isomers that is 
(3-chloro-2,2-dimethylbutane), 
(1-chloro-2,2-dimethylbutane) and 
(1-chloro-3,3-dimethylbutane).
In above case, the molecular formula of all isomers are same i.e.
but chlorine is arranged in different positions of carbon. Thus, results isomers.
The reaction is shown in the image.
I believe it has a positive

The answer is A: Between 50 and 5,000 amino acids
Ionic bonds is formed between a metal and a nonmetal because the metal transfers it's valence electrons to the nonmetal. Electrons doesn't transfer between two nonmetal because both are negatively charged.
Answer:
It’s probably darker because it may have more minerals than the other soils.
