Answer: gaseous molecules are far apart
Explanation:
One of the states in which matter exists is gas. Gases are made of up molecules that are far apart, travelling randomly and rapidly within the containing vessel.
Hence, they are easy to compress whereby they occupy limited space as the gaseous molecules are closely packed in vessels like cylinders and transported to places where they may be needed.
Answer:
c a cold air mass and a warm air mass meet with neither moving
The coefficient of Fe would be 2, the coefficient of Cl2 would be 3, while the coefficient of FeCl2 would be 2.
The balanced equation of the reaction would be as follows:

Thus, the coefficients of Fe, Cl2, and FeCl3 respectively would be 2, 3, and 2.
In other words, 2 moles of Fe require 3 moles of Cl2 to produce 2 moles of FeCl3 in a complete reaction.
