Answer:
C. 2,3,3,4-tetramethylhexane
Explanation:
Answer:
The correct option is C.
Explanation:
Nuclear and chemical reactions are two types of reactions that one usually encounter in chemistry. These two reactions differ from each other significantly. For instance, the nuclear reactions usually involve the nucleus of the involving atoms while chemical reactions has to do with the electrons that are located outside of the nucleus of the atoms. Also, it is only chemical reaction that are influenced by factors such as temperature, pressure, catalyst, etc. Such factors does not determine the rate of nuclear reactions.
Answer:
-The other substances that give a positive test with AgNO3 are other chlorides present, iodides and bromide.
-It is reasonable to exclude iodides and bromides but it is not reasonable to exclude other chlorides
Explanation:
In the qualitative determination of halogen ions, silver nitrate solution(AgNO3) is usually used. Now, various halide ions will give various colours of precipitate when mixed with with silver nitrate. For example, chlorides(Cl-) normally yield a white precipitate, bromides(Br-) normally yield a cream precipitate while iodides (I-) normally yield a yellow precipitate. Thus, all these ions or some of them may be present in the system.
With that being said, if other chlorides are present, they will also yield a white precipitate just like KCl leading to a false positive test for KCl. However, since other halogen ions yield precipitates of different colours, they don't lead to a false test for KCl. Thus, we can exclude other halides from the tendency to give us a false positive test for KCl but not other chlorides.
