    For the first one, you write the 2 formulas without any added subscript that was needed to neutralize the compound. Dont forget to includes the charges for both. Second one is easy. Lets say B did not get A any color. A then finds a new partner, C. C gives A a color. See if you can figure it out.

    @Shalante so they would be NH4+ and So4 2-?
