Mass number is equal to the sum of number of neutrons (neutral subatomic particle) and number of protons (positively charge particle).
Mass number =
Now, atomic number is same as the number of protons i.e. atomic of nitrogen is 7 . Thus, number of protons is also equal to 7.
Therefore,
Mass number =
=
Hence, mass number of nitrogen is equal to .
Answer: i can understand it sorry
Explanation:
For O3, it will have an angle of <120. There are three bonding domains on the central O. 2 bonds and one lone pair. So you start with a bond angle of 120, but the lone pair takes up a little more space than the bonds. so the angle is a little less than 120.
<span>SCl2 will be <109.5. There are 4 bonding domains on S (2 bonds and 2 lone pairs). So the angle starts at 109.5 but due to lone pairs, it is less (similar to a water molecule) </span>
<span>SOCl2 will be <109.5 similar to SCl2 but 3 bonds and one lone pair on eh central atom.</span>
Answer:
Answer is BOTH.

Explanation:
Liz and pat are discussing the pulmonary and systemic circulation. Liz says that the purpose of the pulmonary circulation is to transfer carbon dioxide to the lungs. Pat says the purpose is to carry oxygen away from the lungs. BOTH ARE CORRECT.

I hope this will help you
Explanation:
The air that is inside a ship is much less dense than water. That's what keeps it floating! The average density of the total volume of the ship and everything inside of it (including the air) must be less than the same volume of water.
