The formal charge on nitrogen in NO3- is , where the Lewis structure of the ion is: There is a Lewis structure of NO3 minus ion. The nitrogen atom is connected with one oxygen atom by a double bound and this oxygen atom has two lone pairs of electrons. Each of other two oxygen atoms has three lone pairs of electrons and is connected to the nitrogen atom by a double bond.

For part 1, describe the changes in the colors of the well, if any, as you go from well 1 to well 9—that is, as you go from the well with the least copper(ii) nitrate to the well with the most copper(ii) nitrate. which wells had the most distinct precipitate? for part 2, describe the changes in the colors of the well, if any, as you go from well 1 to well 9—that is, as you go from the well with the least iron(ii) sulfate to the well with the most iron(ii) sulfate. which wells had the most distinct precipitate? for part 3, describe the changes in the colors of the well, if any, as you go from well 1 to well 9—that is, as you go from the well with the least iron(iii) nitrate to the well with the most iron(iii) nitrate. which wells had the most distinct precipitate?
