Kayla Adkins Forensic Chemistry Exam 2 I have been honest and observed no dishonesty. 1. In specific detail‚ describe a published procedure for the definitive identification of Heroin utilizing gas chromatography-mass spectroscopy (GCMS). Heroin is a white crystalline powder with no odor and a bitter taste. It is a derivative of morphine in that the –OH (hydroxyl group) is replaced by an acetyl group‚ -OCOCH3 and has a molecular formula is C21H23NO5 with a molecular weight of 369.42

[pic]The largest creature ever known to have existed on Earth is the present-day blue whale. The largest dinosaur attained a length of about 22 m and weighed about 36 tons. Today’s blue whale is even larger than its ancestors‚ and may reach a total length of 33 m and a weight of 145 tons. This giant animal is placid and shy. On the ocean surface‚ its normal cruising speed is about 12 knots‚ but it is capable of attaining 20 knots in short bursts. The maximum reported depth reached by the species
