name of Exxon Valdez spilled between eleven and 38 million gallons of oil into the Prince William Sound in Alaska. This spill was caused by various influential factors‚ but perhaps one of the most important would be Exxon Shipping Company’s inability to oversee the condition of the crew‚ leading to a fatigued navigator who led the vessel astray‚ which resulted in the massive spill. This oil‚ which is‚ of course‚ hazardous to living creatures‚ resulted in the death of an estimated 250‚000 seabirds‚

Major Oil Spills of the 20th and 21st century In 1989 the Exxon Valdez American oil tanker crashed into the Bligh Reef‚ off the Coast of Bligh Island in Prince William Sound‚ Alaska. The tanker was supposed to turn south after they had reached a certain point‚ Busby Island‚ but because the ship didn’t turn fast enough‚ it collided with the reef. Due to how widespread the damage was‚ 1900km of coastline was polluted. This pollution killed approximately 250‚000 seabirds‚ 2‚800 sea otters‚ 250 bald

Introduction: A balanced chemical equation has reactants and product that has to represent a formulae. The amount of each element‚ number needs to be the same in either side of the equation. (E.g.‚ HCl(aq)+NaHCO3(s) reacts to produce NaCl(aq)+H2O(I)+CO2(g)‚ this is the equation given for this lab). This help us view the study of Law of Conservation of Mass‚ when either side of equation is equally balanced. The calculation for formula mass helps determine if you need to convert grams to a particular

Experiment 7: A Study of Chemical Changes: Types of Chemical Reaction INTRODUCTION Chemical changes are results of chemical reactions. All chemical reactions involve a change in substance and a change in energy. They are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products. There are different types of chemical reaction classified into 4 general types‚ namely‚ Synthesis‚ Decomposition

INTRODUCTION Sugar is one of the main food items consumed in Sri Lanka. The annual per capita consumption of sugar in Sri Lanka is around 30 kg and the total annual requirement of sugar in the country is around 550‚000t. But‚ only about 50‚000 t are produced locally. In a year only 38‚000 t were produced. The balance requirement has to be imported. The total annual expenditure on sugar imports is around Rs. 20 billion.

The Sequence of Chemical Reactions Drew Selfridge Dave Allen‚ Lab partner Instructor Yang February 11‚ 1997 INTRODUCTION This experiment was to recover the most amount of copper after it is subjected to a sequence of reactions. The copper is originally in solid form‚ but the reactions will turn it into free Cu+2 ions floating in solution. The ions will then be regrouped to form solid copper once again. During this process‚ however‚ some of the Cu+2 ions may be lost. The copper will subjected
