I believe the correct response is A. At higher elevations it would take less time to hard boil an egg, because there is less atmospheric pressure.
Answer:
Explanation:
The amine functional group is obtained by subsititution of one or more hydrogen atoms in the ammonia compound.
Ammonia is NH₃.
Then,
- by substituting one hydrogen you obtain R - NH₂.
- by substituting two hydrogens you obtain R' - NH - R''
- by subsituting the three hydrogens you obtain:
R'''
|
R' - N - R''
In this case, the three subsitutuents are silyl groups. The silyl group is derived form silane and is SiH₃. So, the tcompound <em>trisilylamine</em> is:
SiH₃
|
SiH₃ - N - SiH₃
Thus, you can count 3 hydrogen atoms for every silylgroup for a total of <u><em>9 hydrogen atoms in each molecule of trisilylamine.</em></u>
Answer:
True
Explanation:
True because of the law of conservation of mass, the same same amount of atoms will be on both sides of the reaction.
Atomic radius is the distance from the atom's nucleus to the outer edge of the electron cloud.
A) 2, 3 , 2 simply valence the rest
