Question

identify the type of reaction for the chemical equation 2al + 3cucl₂ → 2alcl₃ + 3cu. double replacement reaction, synthesis reaction, single replacement reaction, decomposition reaction

Explanation:

In the reaction \(2\text{Al} + 3\text{CuCl}_2
ightarrow2\text{AlCl}_3 + 3\text{Cu}\), aluminum (Al) replaces copper (Cu) in copper(II) chloride (\(\text{CuCl}_2\)). A single replacement reaction follows the pattern \(A + BC
ightarrow AC + B\), where a more reactive element replaces a less reactive one in a compound. Here, Al (a metal) replaces Cu in \(\text{CuCl}_2\), fitting the single replacement reaction definition. Double replacement involves two compounds exchanging ions, synthesis is combining substances into one, and decomposition is breaking a compound into simpler substances—none of these match here.

Answer:

C. Single replacement reaction
