Answer:
10 nitrogens
Explanation:
The 2 is the number of nitrogens in a molecule of N2. There are 2 of them.
The 5 is a whole different critter. It tells you that it was part of an equation and it took 5 molecules of Nitrogen to balance the equation. You only see numbers to the right of a molecule when the molecule is in an equation.

Answer :
The key differences between a liquid and the a gas is,
A liquid has no fixed shape but it has a volume.
A gas has neither a fixed shape nor a volume.
A liquid has more inter-molecular space between the molecules.
A gas has larger inter-molecular space between the molecules as compared to the liquids.
- Inter-molecular attraction :
A liquid has some Inter-molecular attraction between the molecules because of the low Inter-molecular spacing between the molecules.
A gas has very low or minimum Inter-molecular attraction between the molecules because of the larger Inter-molecular spacing between the molecules.
A liquid flow from the higher to the lower region but a gas flow in all the direction.
