Planet earth as we all live in seems to be the only planet that is capable of supporting human life. Once it is damage beyond repair‚ it might wipe out our species. In the effort of protecting the environment‚ we will consider the effect of our actions before making decisions. Will our actions do any good to the environment or

Experiment #1: Thin-Layer Chromatographic Analysis of Drug Components | Performed on: Wednesday‚ May 8th‚ 2013 | | | 5/15/2013 | | Introduction: The goal of this experiment was to identify an unknown analgesic drug through the use of thin-layer chromatography. The drugs used were‚ Unknown #1‚ caffeine‚ aspirin‚ and acetaminophen. Thin-Layer Chromatography is a technique for identifying substances using a mobile phase (developing solvent) that draws up through a

using thin-layer chromatography. The unknown’s behavior in thin-layer chromatography will be compared with that of its possible component analgesics. The possible unknowns and their analgesic ingredients will be Anacin (aspirin‚ caffeine)‚ Excedrin (acetaminophen‚ caffeine‚ aspirin)‚ Motrin (ibuprofen)‚ and Tylenol (acetaminophen). Introduction Thin-layer Chromatography(TLC) was the method used to figure out and identify the drug. TLC is done on a plate that is coated with a layer of absorbent

These elements like sodium‚ chloride‚ ferrocyanide and other impurities seep into our environment when the snow or ice melts‚ and poses a threat to water bodies‚ soil‚ vegetation and large number of species sustaining on them (Environmental‚ Health and Economic Impacts of Road Salt).

pollution will dramatically decline if the authorities are not reluctant when it comes to making disposals more accessible so that a clean environment can be maintained. According to (SWMCOL 2010) in Trinidad and Tobago‚ the average person generates approximately 4 lbs of waste per day This amounts to approximately 1‚000 tons of waste that reaches the landfill sites per day Apart from this‚ large quantities of waste are also improperly disposed of‚ and as a result‚ pollute our streets‚ drains‚ rivers‚ beaches

In the recent years there has been a significant rise in people’s concern for the environment. We all affect the natural environment‚ but we are often are unaware of how much we affect it. There is no part of the earth that does not remain affected by our actions. Our actions are now threatening the health of our planet‚ the land we live and work on‚ the water supply‚ the ozone layer‚ the animal species as well as the health of our species. With this it is easy to say "The problem is too great and

One of the dilemmas concerning our environment is saving wild life creatures. Cutting down trees is killing their habitat and ways of living. How would you like it if someone came into your neighbourhood and started bulldozing the houses down? Many living species have died because of the habitat changes they have to go through. Many oceans and other water bound areas in the world are being polluted by human waste. It’s killing all water creatures and making water unsanitary. If you really think about
