GEOGRAPHY REVIEW NOTES: UNIT 1 Locating Places on a Map Remote Sensing – The technology for studying Earth by using images and photographs above its surface GPS – Global Positioning System. A satellite based position-finding system that circles Earth in precise orbits. Geostationary Satellite – Satellite that only stays on the equator and turns with it as Earth rotates (eg. Weather satellites‚ communication satellites) Near-Polar Satellite – Follows a fixed north-south orbit as the Earth rotates

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
