Writing Word Equations

  1. Feb 18, 2009 #1
    1. The problem statement, all variables and given/known data

    Write word equations to show the changes in:

    1)Hydrochloric Acid and Mossy Zinc
    2)Manganese Dioxide and Hydrogen Peroxide
    3)Hydrochloric Acid and Rolaids
    4)Passing electricity through copper (II) chloride (electrolysis)
    5)Silver nitrate and sodium chloride

    2. Relevant equations



    3. The attempt at a solution

    5) Silver Nitrate(liquid) + Sodium Chloride(liquid) -> Silver Chloride (liquid)
    1) Hydrochloric Acid + Zinc -> Zinc Chloride?
    2) Manganese Dioxide + Hydrogen Peroxide -> Hydrogen Dioxide ??

    I have no idea how to do it, especially for #4.

    Is silver chloride soluble?

    No such thing as hydrogen dioxide. However, mangan can be oxidized.

    1 is OK.

    Google electrolysis, #4 is easier than you think.
