  • Shown In Figure Surface Of The Earth
    1,655 words
    The oceans are said to be the source of life. The enormous, blue, calm oceans are the signatures of the planet earth. They cover nearly three-fourths of the surface of the earth. This is equal to 71 percent of the earths entire surface or about 361 million sq km (140 million sq mi). Its average depth is 5000 m (16, 000 ft), and its total volume is about 1, 347, 000, 000 cu km (322, 300, 000 cu mi). This includes the Atlantic, Pacific, and Indian oceans. These oceans are bordered by the continent...

  • Niels Bohr Model Of The Hydrogen Atom
    365 words
    Niels Bohr's model of the hydrogen atom, was the primary reason for the understanding of energy levels. Bohr was able to explain the bright line spectrum of hydrogen. Sparked by the recent discovery of the diffraction patterns, scientists believed electrons could be described as waves. Bohr hypothesized that energy is being added to the hydrogen gas in the electricity form, and then leaving the gas in the form of light. He figured the light rays to be quantized, meaning only certain frequencies ...

  • Life On Earth H 2 O
    726 words
    The first thing water reminds us of is the clear liquid in our water bottles. However, water is more than a normal substance. Water is the beginning and the continual of life on earth. Because of its many unique properties, water was able to start life on our planet. The simple structure of H 2 O is the source of all water's properties. With two hydrogen atoms sticking to an oxygen atom in a tetrahedron shape, water is considered as a polar molecule. Because oxygen is very electronegative, it pu...

  • Ph Of 5 Sulphur Dioxide
    1,087 words
    Acidity is measured using a pH scale, with the number 7 being neutral. A substance with a pH value of less than 7 is acidic, while one of a value greater than 7 is basic. A substance with a pH of 6 is 10 times more acidic than another with a pH of 7. Usually the pH of 5. 6 has been used as the baseline in identifying acid rain, although there has been much debate over the acceptance of this value. Interestingly enough, a pH of 5. 6 is the pH value of carbon dioxide in equilibrium with distilled ...

    Two Americans and a Japanese were awarded this year's Nobel Prize in Chemistry for developing more efficient chemical reactions to produce many medicines, including L-dopa, the standard treatment for Parkinson's disease. Dr. William S. Knowles, 84, of St. Louis, who retired from the Monsanto Company in 1986, and Dr. Ryoji Noyori, 63, director of the Research Center for Materials Science at Nagoya University in Japan, shared half of the $ 950, 000 award.

  • Amount Of Energy Oxygen Atoms
    1,983 words
    Planning In this investigation I will be burning alcohols to heat up a beaker of water. I will be burning five alcohols, methanol, ethanol, propanol, butanol and pentanol. The aim is to find out how much energy is produced when burning these alcohols. An alcohol is a series of organic homologous compounds, with the general formula Cn H n + 1 OH´ . Alcohols react with oxygen in the air to form water and carbon dioxide. The reaction that is involved in burning alcohols is exothermic because ...

  • Surface Of The Water Hydrogen Bonds
    984 words
    Water is the most important substance in our evolution and our daily lives. Without water, life as we know it would not have been possible. This essay will examine the water molecule in order to ascertain how it brought about Earths thriving ecosystem and how important it is to us today. Each water molecule consists of one oxygen atom and two hydrogen atoms. The oxygen atom (or the apex of the water molecule) bears a slight electronegative charge while hydrogen possesses a more positive one 1 (f...

    The Search for Intelligent Life A pioneer in Nasa's Search for Extraterrestrial Intelligence (SETI), Frank Drake, proposed an equation that calculates the number of civilizations in the galaxy. It is based on the fraction of stars with planets, the proportion of those that are inhabitable and the life of technological civilizations (Overbye 46). Optimists, using the equation, have arrived with 1 million civilizations in the milky way alone. Looking at the size of the universe and how common cert...
