When solid aluminum metal is reacted with diatomic chlorine gas, solid aluminum chloride is formed. This reaction is an example of synthesis or chemical combination in which two elements, aluminum and chlorine combine to form a new compound aluminum chloride.
Word equation: Aluminum (s)+ Chlorine (g)---> Aluminum chloride(s)
Molecular formula of the product formed is
.
Therefore the balanced chemical equation representing the reaction of solid aluminum with gaseous dichlorine can be represented as,
