Final answer:
The reaction between aluminum metal and chlorine gas to form solid aluminum trichloride is a synthesis reaction.
Step-by-step explanation:
The reaction between aluminum metal and chlorine gas to form solid aluminum trichloride is an example of a synthesis reaction. In this type of reaction, two or more reactants combine to form a single product.
The balanced chemical equation for this reaction is:
2 Al (s) + 3 Cl2 (g) → 2 AlCl3 (s)
When 17.467 grams of chlorine gas react with excess aluminum, the mass of solid aluminum chloride formed can be calculated using stoichiometry.
