Answer:
There are no unpaired electrons.
Explanation:
There are no unpaired electrons in the Lewis symbol for a nitride ion(
).The nitride ion has a charge of -3. The negative charge on the Nitride ion indicates a gain in electrons . Nitrogen has 5 valence electrons that is the number of electrons that are in its outer shell .The total number of electrons that the nitride ion has is equal to 5+3 = 8 electrons . Electrons usually appear in pairs and obey the octet rule therefore the nitride ion has four electron pairs no unpaired electrons.

Thx Have a Fantastic day :)
Explanation:
The answer is 100 Pa.
The formula for calculating pressure is :
<u>Pressure = Force ÷ Area</u>
<u />
We are given that :
We also know that :
<u>Force = mass ×g</u>
<u />
So, force will be :
Now, we can finally calculate pressure :
