We are trying to restore the dichromate finish on some carburetors to like new condition. We are using a dry media in a tumbler that leaves no residue. Following the instructions to the letter from the kit that we bought, the carburetors dichromate finish comes out uneven with various shades throughout.

Question: What is the chemical formula for ammonium dichromate? When are parentheses used in writing chemical formulas? Lisa Malone Answer: Ammonium dichromate: (NH4)2Cr2O7 Parentheses are used when there are more than one polyatomic "functionalities" in a molecule and the formula has to be written out.
