Question

al + cl₂ → alcl₃
synthesis
decomposition
single displacement
double displacement
combustion

Explanation:

Step1: Recall reaction types

Synthesis reaction: \(A + B
ightarrow AB\). Decomposition: \(AB
ightarrow A + B\). Single - displacement: \(A+BC
ightarrow AC + B\). Double - displacement: \(AB + CD
ightarrow AD+CB\). Combustion: \(C_xH_y+O_2
ightarrow CO_2 + H_2O\) (for hydrocarbons).

Step2: Analyze given reaction

The reaction \(2Al+3Cl_2
ightarrow 2AlCl_3\) has two reactants (\(Al\) and \(Cl_2\)) combining to form one product (\(AlCl_3\)).

Answer:

Synthesis
