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

special occasions like independence day. The excitement produced by fireworks like ‚ brightening the night sky and plunging it with vivid displays of colour and insignificant‚ which makes them a crowd pleaser. Behind all the excitement of fireworks‚ chemistry plays an important role in creating the vivid colours we witness lighting up the sky. The actual chemical reactions that take place in the explosions require the use of oxidisers‚ reducing agents and binders. The additions of varying metal chlorides

What are the impacts of chemistry on society? In: Biology [Edit categories] Answer: the impacts chemistry have on a society is huge. every single material that we come in contact with‚ in our daily ife is composed of chemicals there are negative and positive effects of chemistry but the negative effect is mainly due to the inability of a man to think carefully first of all lets take the example of drugs. drugs are composed of chemicals ofcourse‚ but these drugs can be used for a good purpose
