    What is the balanced reaction between Sodium Hydroxide and Copper Bromide?
    The balanced reaction between sodium hydroxide (NaOH) and copper bromide (CuBr₂) is:

    2 NaOH + CuBr₂ → Cu(OH)₂ + 2 NaBr

    Här är en uppdelning av reaktionen:

    * reaktanter:

    * Natriumhydroxid (NaOH) är en stark bas.

    * Copper bromide (CuBr₂) is a soluble ionic compound.

    * Produkter:

    * Copper(II) hydroxide (Cu(OH)₂) is a blue-green precipitate that forms.

    * Sodium bromide (NaBr) is a soluble ionic compound that remains in solution.

    The reaction is a double displacement reaction. This means that the positive and negative ions of the reactants switch places to form the products.

    Here's how to balance the reaction:

    1. Start with the unbalanced equation: NaOH + CuBr₂ → Cu(OH)₂ + NaBr

    2. Count the number of atoms of each element on both sides:

    * na: 1 till vänster, 1 till höger

    * o: 1 till vänster, 2 till höger

    * h: 1 till vänster, 2 till höger

    * cu: 1 till vänster, 1 till höger

    * br: 2 on the left, 1 on the right

    3. Adjust the coefficients in front of each compound to balance the number of atoms:

    * Place a "2" in front of NaOH and NaBr to balance the Na, O, H, and Br atoms.

    The balanced equation is 2 NaOH + CuBr₂ → Cu(OH)₂ + 2 NaBr
