    Any chemistry students or anyone with any knowledge able to work these out for me? i've come up with answers but am almost sure there wrong been sat here for way to long..

    Write the full and balanced chemical equations (you must include ‘states’) for the precipitation reactions between:

    Lead Nitrate (Pb(NO3)2) and potassium bromide (KBr) forming a precipitate of lead chloride (PbBr2)

    Lead Nitrate (Pb(NO3)2) and Magnesium chloride (MgCl2) forming a precipitate of lead chloride (PbCl2)

    Silver Nitrate and potassium chloride forming a precipitate of silver chloride

    Barium chloride and sodium sulphate forming a precipitate of barium sulphate

    Sorry you've not had any responses about this. Are you sure you've posted in the right place? Here's a link to our subject forum which should help get you more responses if you post there.

    You can also find the Exam Thread list for A-levels here and GCSE here. :dumbells:

    Just quoting in Puddles the Monkey so she can move the thread if needed
    (Original post by Puddles the Monkey)

    1. Write out the symbols, compounds must have full electron configuration. Eg. hcl, h2so4...
    2. Balance the number of each atom on each side by changing the ratio
    Try it by yourself so you can improve and post your working if you want to get confirmed
