  • Single Replacement Reaction: Al + CuCl2 - True Statements & Explanation
    Here's a breakdown of the reaction and the true statements:

    The Reaction:

    Al + CuCl₂ → AlCl₃ + Cu

    Explanation:

    * Single Replacement: This is a single replacement reaction because aluminum (Al) is more reactive than copper (Cu). Aluminum displaces copper from its compound (CuCl₂).

    * Balancing: The balanced equation shows that 2 moles of aluminum react with 3 moles of copper chloride to produce 2 moles of aluminum chloride and 3 moles of copper.

    * Product Formation: The products of the reaction are aluminum chloride (AlCl₃) and copper (Cu).

    True Statements:

    1. Aluminum is more reactive than copper. (This is the basis of the reaction)

    2. Copper is displaced from copper chloride. (The reaction shows copper being replaced)

    3. The products are aluminum chloride and copper. (This is the outcome of the reaction)

    4. The reaction is balanced. (The balanced equation ensures equal atoms on both sides)

    False Statements:

    * Copper is more reactive than aluminum. (This is incorrect; aluminum is more reactive)

    * The reaction is a double replacement reaction. (This is incorrect; it's a single replacement)

    * The products are aluminum and copper chloride. (This is incorrect; the products are aluminum chloride and copper)
