meaning oil. Petroleum occurs in the earth in combination of any of the four states: gas‚ liquid‚ semisolid‚ and solid. Chemically‚ petroleum is a mixture of carbon‚ hydrogen and oxygen (called hydrocarbons) with minor amounts of nitrogen‚ oxygen‚ and sulfur as impurities along with heavy metals. Petroleum is organic; it contains complex carbon‚ hydrogen molecular structures (CH4) called chains that are linked together to form long-chains of more complex molecules. TYPES OF PETROLEUM: There are three

Battle of Iwo Jima Iwo Jima is a part of a chain of volcanic island groups called the Nanpo Shoto that extends about 750 miles south of Japan. The island lies within the center of the Volcanic Island group and is about 650 miles south from Japan. At the shape of a pork chop the island of Iwo Jima is just 4 miles long Stretching from the Northwest to Northeast. at the widest point of Iwo Jima the island is just 2 and a half miles across while at its narrowest the island is only seven hundred yards

cause of this gas being put into the air is from car exhausts. In addition‚ gas that is being used in lawnmowers also emits nitrogen oxides‚ however in smaller amounts. Along with those hazardous gases there are other air pollutants like soot‚ and sulfur

Does Foreign Direct Investment Harm the Host Country’s Environment? Evidence from China Feng Helen Liang ∗ Haas School of Business‚ UC Berkeley This Version: April 12‚ 2006 Abstract As more manufacturing is moved to the developing countries‚ policy makers become concerned with the environmental consequence. Relatively lenient environmental policies in the developing countries may give them a comparative advantage in pollution intensive goods‚ and openness to trade and foreign direct investment

Seawater seeps into these cracks and is heated by the molten rock below the Earth’s crust. As the water heats‚ chemical reaction begin to occur‚ and oxygen and minerals are removed from the water. As it goes deeper and gets hotter‚ certain metals and sulfur dissolve into it‚ and then the fluid begins to rise. It gushes back to the ocean floor‚ meeting with the near-freezing‚ oxygen-rick seawater‚ causing more chemical

THE ACID DECOMPOSITION OF THIOSULFATE Aqueous solutions of thiosulfate‚ S2O32-(aq) are stable if neutral or basic‚ but decompose quickly when the thiosulfate is dissolved in acid according to the equation: Sulfur dioxide is a gas at room temperature‚ but is very soluble in water. Sulfur‚ a water insoluble solid‚ forms a colloidal suspension. As a result‚ the solution first becomes cloudy and then opaque. We can take advantage of the developing opacity of the reaction system to do a kinetics study
