The number of Fe atoms within a single FeCl2 molecule are one.
Explanation:
Metallic iron produces only ferrous chloride (FeCl2) on treatment with hydrochloric acid. Hydrogen gas is also liberated as the other product. But when iron is heated with chlorine gas, ferric chloride (FeCl3) is formed.
Total number of atoms within a single FeCl2 molecule are 3 atoms.
The number of Fe atoms in FeCl2 molecule are one.
Number of Cl atoms in FeCl2 molecule are two.
A phase change from Gas to liquid means that it was cold outside and so the molecules went from being very free moving to forming bonds with one another due to the cold.
Answer:
Explanation:
Synthesis is the combining of two elements or atoms into a compound/mixture. Decomposition is the breaking down of a compound/mixture into individual atoms or elements. In conclusion, on is the building up of a compund/mixture and one is breaking down.
