Fluorine, chlorine, and bromine all react with heated iron wool. Table 1 shows the observations of these reactions.
Table 1
| Halogen | Observation of reaction with heated iron wool |
|---|---|
| Fluorine | Reacts explosively |
| Chlorine | Reacts very vigorously with a bright orange glow |
| Bromine | Reacts vigorously with a dull red glow |
When heated iron wool is reacted with chlorine, iron(III) chloride is formed.
Write the word equation for this reaction.
