Answer:
Multiple organisms may be affected by the loss of a plant species.
Explanation:
Organisms that feed directly off the lost plant will be affected, and because of that, organisms that feed off those organisms will be affected. This could also affect other organisms like parasites. Other plant species may be affected from the loss of a competitive species. This could affect organisms that feed off that plant, and the organisms that feed off those organisms.
Answer:
<u>One lone-Pair is present in Ammonia</u>
<u></u>
Explanation:
The number of valence electron in N = 5
The number of Valence electron in H = 1
The formula of ammonia = NH3
Total valence electron in ammonia molecule = 5 +3(1) = 5+3 = 8
The lewis structure suggest that :
Nitrogen completes its octet by sharing the electron pair with 3 hydrogen atoms.
3 electron of Nitrogen are involved in sharing with Hydrogen
So,<u><em> remaining two electron are left non-bonded</em></u> . Hence they exist as lone- pair
So, there is only 1 lone pair in the ammonia molecule .
The shape of NH3 is bent according to VSEPR theory . This is so because the presence of 1 lone pair causes more repulsion and occupy more space.
Thus the lone pair is changing the shape of the ammonia molecule . It also increase the dipole moment of the molecule , which gives polarity to it.
Answer:
The halogens are extremely reactive, whilst the noble gases are mainly inert.
Only some noble gases tend to form compounds, such as xenon and krypton. However, some like helium, almost have no compounds at all.
Noble gases also have octet rule shells, which causes the little reactivity associated with them.
To form bonds with noble gases, a lot of energy is required to form those bonds.
Halogens, on the other hand, are extremely reactive. Compounds like chlorine and fluorine must be stored carefully, as they will oxidise anything that they can find, just to get one extra electron to get an octet configuration.
Hope this helps :)
