Try to imagine‚ if one day‚ you can no longer find any plastic packaging‚ what would your life be? Say‚ when you bought a chunk of fresh meat‚ normally placed in a polythene plate with a layer of food wrap‚ the plastic packaging of which disappeared now‚ what could you do to take it away hygienically? Or when you bought some toilet cleaners‚ how could you bring it home in order not to harm your hands without a plastic bottle provided? Plastic packaging is everywhere that one can never avoid in our

and to understand how a reduction-oxidation relationship works to produce spontaneity. Lastly‚ these results were used to determine the Faraday’s constant and Avogadro’s number by electrolysis‚ which is chemical decomposition produced by passing an electrical current through a solution with ions. The primary objective of part one of this experiment was to discover how the properties of an electrochemical cell works. An electrochemical cell is based on an oxidation-reduction reaction and is composed

Plastic and Environment A plastic material is any of a wide range of synthetic or semi-synthetic organic solids that are moldable. Plastics are typically organic polymers of high molecular mass‚ but they often contain other substances. They are usually synthetic‚ most commonly derived from petrochemicals‚ but many are partially natural. Composition Most plastics contain organic polymers. The vast majority of these polymers are based on chains of carbon atoms alone or with oxygen‚ sulfur‚ or nitrogen

Acidity’s effects on Fruit Browning Aim: To test whether the acidity of the surface area of an apple has an effect on the rate of enzymatic browning over 70 minutes. Hypothesis: the more acidic the surface area the longer it takes for the fruit to oxidise. Variables: Independent: acidity of surface area of the apple Dependent: the progression of melanin (brown pigment) after 70 minutes Controlled/fixed: time of day‚ knife used to cut fruit‚ portion of fruit‚ environment

Transcendentalism Wrap-Up Project Some of the songs on the CD aren’t exactly clear on their transcendentalist properties‚ so I decided to just be Thoreau (yes that is a pun) and go through and define the songs’ transcendentalist properties. Tracks 1.) The Dive by Eyedea & Abilities- Aside from being an awesome and thought provoking song‚ this track opens up the ideas of Emerson’s Self- Reliance for me pretty well. The song talks about how someone goes out to look for the meaning of life and existence

16 April 2012 Essay III How Plastic Pollution is Out of Control Many individuals underestimate the amount of plastic we use each day. According to the article “Plastic Bags Wars”‚ “the world consumes 1 million plastic shopping bags every minute”. Plastic bags‚ along with many other types of plastics‚ have become a leading source of pollution worldwide (Doucette). Captain Charles Moore‚ founder of the Algalita foundation states that we use two million plastic bottles in the United States every

I held the chemicals at approximately a 90 degree angle for consistency Introduction: Redox reactions occur when both oxidation and reduction take place. All atoms can be assigned an oxidation number‚ which is a positive or negative number that help in determining the reducing and/or oxidizing agents in an equation. An increase in the oxidation number of an atom from

Plastic Pollution Introduction The world population is living‚ working‚ vacationing‚ increasingly conglomerating along the coasts‚ and standing on the front row of the greatest‚ most unprecedented‚ plastic waste tide ever faced. Washed out on our coasts in obvious and clearly visible form‚ the plastic pollution spectacle blatantly unveiling on our beaches is only the prelude of the greater story that unfolded further away in the the world’s oceans‚ yet mostly originating from where we stand: the
