| Its kinda funny that they would give you a combustion reaction for one of the written formulas. Its a free 2 points if you know one of the most basic concepts of chemistry. I also got 2.6 for the pH and put the exact same answer as primitivefuture, minus that it turns brown when exposed to nitrogen. I believe you are correct though. TM2000 I think they might take off a point if you don't mention shielding on 7. Hoping for a 3 |
