Andrea Matcham Environmental Science Waste Management Strategies June 19th‚ 2013 Waste Management is the process of disposing‚ managing and monitoring of our waste materials. These important steps help us to reduce or eliminate the effects it has on our health and the environment. By practicing waste management we are observing our consumption of resources and working to reduce the hazardous waste used. These practices can provide enormous change in our lives and give hope to future

Part 1. Hydrocarbon Nomenclature From International Union of Pure and Applied Chemistry (IUPAC) General Form of IUPAC Nomenclature [branching substituent(s)] Root [Suffix] Rules: 1. Identify the longest continuous chain of carbon atoms. This chain determines the parent name (root) of the alkane. The parent suffix for alkanes is‚ not surprisingly‚ -ane. For chains of equal length‚ pick the one with the most substituents. (Note: I number all possibilities going from left to right

INTRODUCTION From natural gas‚ crude oils‚ and other fossil materials such as coal‚ few intermediates are produced that are not hydrocarbon compounds. The important intermediates discussed here are hydrogen‚ sulfur‚ carbon black‚ and synthesis gas. Synthesis gas consists of a nonhydrocarbon mixture (H2‚CO) obtain- able from more than one source. It is included in this chapter and is fur- ther noted in Chapter 5 in relation to methane as a major feedstock for this mixture. This chapter discusses

------------------------------------------------- Definition Esters are chemical compounds consisting of a carbonyl adjacent to an ether linkage. They are derived by reacting an oxo acid with a hydroxyl compound such as an alcohol or phenol. Esters are usually derived from an inorganic acid or organic acid in which at least one -OH (hydroxyl) group is replaced by an -O-alkyl (alkoxy) group‚ and most commonly from carboxylic acids and alcohols. That is‚ esters are formed by condensing an acid with

plastics exist:[1] Bioplastics‚ whose components are derived from renewable raw materials and plastics made from petrochemicals with biodegradable additives which enhance biodegradation There are concerns that "Oxo Biodegradable (OBD)" plastic bags may release metals‚ and may require a great deal of time to degrade in certain circumstances.[8] Furthermore‚ OBD plastics may produce tiny fragments of plastic that do not continue to degrade at any appreciable rate

CHEM 301 LECTURE Unit 1 0 . COORDINATION CHEMISTRY Factors t hat affect solubility: Common ion: decrease in solubility Complex ion: increase in solubility How does complex ion formation increase solubility? Consider the complex ion formation between silver and ammonia: + Ag + 2NH3 A g(NH3 )2 + Kf = 1 .5 x 10 7 where Kf i s the formation constant (always >1 ‚ formation of the complex is highly favorable) Complex ion formation increases the solubility of sol ids in water

that was used in this lab‚ XL-1 Red Mutator‚ lacked three different repair methods used to correct mistake in DNA replication. If a mistake occurred‚ the E. coli would not be able to make repairs via DNA polymerase backtracking‚ mismatch repair‚ or oxo-dGTP hydrolysis. The E. coli will still be able to use the other ways to repair mistakes including SOS repair. The result is that the XL-1 Red Mutator strand has a thousand more mistakes than an E. coli strand that has all its repair options. This
