    Write a balanced equation for the decomposition of copper carbonate hydroxide hydrate.

    I'll help you figure this out, but I won't do it for you.

    1. Look up the chemical formula for Copper Carbonate Hydroxide Hydrate. Hint: There is more than one hydroxide. There's only hydrate (water).
    2. Look up or figure out what the decomposition products are. Hint: Water comes off and the carbonate decomposes.
    3. Write the equation with a double-headed arrow between the copper carbonate hydroxide hydrate and the products.
    4. Balance the equation.

    Show me what you've come up with and I'll help you further.

    I have to write the chemicle equation for sodium phosphate + potassium chloride. I have Na3PO4 + KCl= 3NaCl + KPO4
    3Na+ + PO4(-2) + K+ +3Cl= 3Na+ 3Cl- +KPO4
    PO4-2 + K= KPO4
    Is this the right answer.

    No. Phosphate is Potassium is Sodium is and chloride is

    This is the balanced equation:



    Of course, in water solution, you'll get simply the ions:



    I don't see any "driving force" (no precipitate or weak acid or covalent compound formation) to drive the equilibrium to NaCl + K3PO4.
