Question

balance the reaction, then label the reaction type: 2 al + 6 hcl → 3 h₂ + 2 alcl₃ reaction type:

Explanation:

Step1: Analyze the reaction

The reaction is between aluminium (\(Al\)) and hydrochloric acid (\(HCl\)) to form hydrogen gas (\(H_2\)) and aluminium chloride (\(AlCl_3\)).

Step2: Check the balanced equation

The balanced equation is \(2Al + 6HCl
ightarrow3H_2 + 2AlCl_3\).

Step3: Determine the reaction type

In a single - replacement reaction, one element replaces another element in a compound. Here, aluminium (\(Al\)) replaces hydrogen (\(H\)) in \(HCl\).

Answer:

Single - replacement reaction
