in a way that it is turning into a non-renewable resource. The world’s supply of fresh water is threatened by growing levels of pollution‚ more so in developing countries than developed. There are many environmental problems associated with the consumption of water in a way that transforms it into a non-renewable resource. Water pollution heavily affects the functionings of an ecosystem as water pollution directly affects both plants and animals. If current trends of water pollution continue many

Chapter 1 Carbon Compounds and Chemical Bonds. (Covered material: 1.1 - 1.8; 1.12 - 1.17) 1. Structural Theory – most fundamental theory of Organic Chemistry (developed independently by A. Kekule‚ A. Couper and A. Butlerov between 1858 and 1861). Organic Compounds – compounds of carbon and hydrogen. Other elements frequently found in organic compounds are: oxygen‚ nitrogen and halogens (F‚ Cl‚ Br‚ I); less frequently found are: sulfur and phosphorus. Review Periodic Table for determining valence

or the first 21 years of our existence we are supposed to be schooled‚ prepped‚ and pruned for a job that we might not get‚ or for that matter enjoy‚ so that we can maybe one day get a "guarantee" of a life that we are not even sure we want. This uncertainty is perpetuated by the fixation humanity has with the future. People are willing to sacrifice the present moments of their lives‚ in hopes of one day achieving the ability to fulfill the desires that they hold at bay. The issue is that the future

is to investigate the quantity of removal of Malachite Green dye from aqueous solution using Activated Los Pantanos De Villa Carbon (ALPC). Generally‚ dyes are used in chemical‚ textile‚ paper‚ printing‚ leather‚ plastics and food industries. The need for the treatment of dye contaminated waste water passed out from the industry. In this study‚ Los Pantanos De Villa Carbon was studied for its potential use as an adsorbent for removal of Malachite Green dye. This study is focusing on various
