Geology Test 3 What type of metamorphism is caused by high temperature and high pressure imposed over a large volume of crust? Regional What are the local rocks under our feet called? Caliche A rock is hydrothermally altered by burial. If the rock is buried to 3 km deep and the local geothermal gradient is 25 degrees Celsius per km‚ then how hot is the rock? 75 degrees Celsius Which of following minerals will dissolve completely during weathering? Calcite Marble forms when one

Exp.11) Identification of unknown ketones. Introduction: Given five samples of a known ketone derivative‚ the purpose of this experiment is to identify which unknown ketone derivative corresponds to the five known samples. In other words‚ using specific methods of compound detection‚ it is possible to match an unknown compound with a known compound because similar compounds will display similar characteristics. In this experiment‚ identification of the unknown ketone is accomplished through thin

Describe in basic terms how elements were/are formed during the big bang (including the reasons why only H/He formed abundantly)‚ during normal stellar operation (including why some elements such as Si and Fe were formed more abundantly)‚ and during supernova processes/explosion Big bang only thing that forms out of the big bang is the nuetrons. Protons plus electrons = hydrogen. Hydrogen fuses the helium. There are no stable atoms with 5 or 8 nucleons (hydrogen would have 5‚ helium would have

in the formation of the plastics of many different products humans use daily. In commercial production‚ the para‚ para’ isomer (p‚p’) is the preferred product. The ortho‚ para’- BPA isomer is also produced but in low levels and is removed by recrystallization. BPA can come in the form of a white to tan crystal‚ flake‚ or powder. This compound has a mild phenolic odor yet it is not volatile. BPA is not sold directly for consumer use but serves as the raw material that makes up the polymers used to

Extraction of Caffeine from Lipton® Tea Leaves Nathaniel Camangon*‚ Kaila Bumagat‚ Franz Mari Burgos‚ Remigio Callanta Department of Chemistry‚ College of Science‚ University of Santo Tomas‚ Manila‚ Philippines Abstract This experiment mainly focuses on the extraction of pure caffeine by multiple extraction from commercially acquired tea leaves and determining its purity by melting point determination. A 0.02% yield of pure caffeine was obtained from 10.4978g of tea leaves (4 tea bags).

ABSTRACT The primary aim of this paper is to study the Microstructual influence on fracture resistance in 7000 seriers aluminium alloys. Fracture toughness is an indication of the resistance of a material to physical separation by a process of unstable macrocrack propagation. The microstructural features such as coarse particles of intermetallic (IM) phases‚ dispersoids‚ inter- and intragranular precipitates‚ precipitate-free zones ‚ grain size and orientation are known to exert significant effects

INTRODUCTION: Penicillin is the basis for most of the antibiotics in the world just as aspirin is the basis for many drugs. Therefore‚ if there had been only two drugs to invent‚ it would be down to penicillin and aspirin. Hippocrates‚ the father of modern medicine lived sometime between 460 B.C and 377 B.C. Hippocrates has left historical records of pain relief treatments‚ including the use of a powder made from the bark and leaves of the willow tree to help heal headaches‚ pains and fevers.
