Body Of Water Maltese Falcon
1,356 wordsA Unique Setting in the Changing World of Early 20 th Century Detective Fiction The Pacific coast port city of San Francisco, California provides a distinctively mysterious backdrop in Dashiell Hammett's The Maltese Falcon. Unlike many other detective stories that are anchored in well-known metropolises such as Los Angeles or New York City, Hammett opted to place the events of his text in the lesser-known, yet similarly exotic cultural confines of San Francisco. Hammett used his own intricate kn...

Southern Hemisphere Magnetic Field
1,422 wordsJupiter, the largest of the Jovian planets, reigns supreme throughout the solar system. Named after the Roman god Jove, the ruler of Olympus; "Jupiter is the fifth planet from the sun and is also the largest planet in the Earth's solar system. It is 318 times more massive than Earth and is two thirds of the planetary mass in the solar system. Jupiter's surface, unlike earth, is gaseous and not a solid. It is about 90 % hydrogen and 10 % helium with traces of methane, ammonia, water and rock. Jup...

Lemon Juice Hydrogen Ions
527 wordspH is the measure of H+ (a proton) a concentration of a solution. In order to understand pH, a scale has been designed, this scale ranges from 0 to 14. Anything from 0 to 6. 99 is acidic, a substance that increases hydrogen ions concentration in a solution, such as lemon juice. If the scale ranges from 8 to 14 would be determined as a basic solution, a substance that reduces the hydrogen ions concentration in a solution, an example of this would be ammonia. If the solution concentrate has a pH o...

Sodium Hydroxide Universal Indicator
854 wordsExperiments to Determine the Effect of Acids & Bases on Different Indicators and the pH of Common Cleaning Agents The aim of the first set of experiments is to find out and record the colour changes that are observed after a certain indicator is mixed with acids and bases to form a colour reaction. Once the selected indicator has been mixed with a acid that is both weak and strong and a base / alkali that is both weak and strong we are to record the colour and choose another indicator. The purpo...

Nitrous Oxide Liquid Nitrogen
551 wordsNitrogen was isolated by the British physician Daniel Rutherford in 1772 and recognized as an elemental gas by the French chemist Antoine Laurent Lavoisier about 1776. Properties Nitrogen is a colorless, odorless, tasteless, nontoxic gas. It can be condensed into a colorless liquid, which can in turn be compressed into a colorless, crystalline solid. Nitrogen exists in two natural forms of isotopes, and four radioactive isotopes have been artificially prepared. Nitrogen melts at - 210. 01 C (- 3...

Ph Of 5 Sulphur Dioxide
1,087 wordsAcidity 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 ...

Role In The Nitrogen Cycle Nitrogen From The Atmosphere Tree
374 wordsThe nitrogen cycle is a complex biological cycle involving the recycling of usable nitrogen. If this cycle ceased to occur, all forms of life on the planet would die. All life forms, including humans, use nitrogen in compounds called amino acids. These amino acids then act as building blocks for proteins. Nitrogen, in fact, is the most abundant element in the atmosphere. Most organisms are unable to use this nitrogen from the atmosphere and rely on the nitrogen in the soil. The cycle consists of...

Elements Are Required Synthetic Fertilizers Fertilizer
247 wordsFertilizer is a substance added to soil to help plants grow. Fertilizer is divided into two groups: natural and synthetic. Fertilizer provides one or more of the chemical elements essential for plant nutrition. Natural fertilizers are items like animal excrement, straw, other plant materials, guano, animal tankage and meat and bone meals, and bone meals and flours. All natural fertilizers are from nature. Synthetic fertilizers come in either liquid or solid. They are usually classified into 10 g...

Plant Growth Harmful Effects
2,117 wordsMany questions have Fertilizers Fertilizers Many questions have been raised concerning the use of fertilizers, why plants require them, and about the benefits they bring. Fertilizers have a significant effect on humanity, as they form the basis of food production. The addition of fertilizers assists enrichment of soil fertility and corrects nutrient deficiencies so that plants can grow more healthily, provide crops and food for people, and increase food production. In this way, fertilizers are s...

Fossil Fuels Global Warming
1,982 wordsThe Potential Markets Hydrogen ANALYSIS The Potential Markets For Non-Fossil Fuel Hydrogen? Hydrogen, most of it produced from fossil fuels, is already widely used in the chemicals industry, notably in the manufacture of fertilizers and petrochemicals. It would therefore be possible to substitute NFFH in this market. However, the total that could be absorbed by 2040 is unlikely to represent more than about 3 % of current total world energy demand. ? NFFH could be used to satisfy much of the dema...

Blood Pressure One Hundred
566 wordsIn vertebrates, kidneys Kidneys Kidneys In vertebrates, kidneys are the two major organs of excretion. Excess water, toxic waste products of metabolism such as urea, uric acid, and inorganic salts are disposed of by kidneys in the form of urine. Kidneys are also largely responsible for maintaining the water balance of the body and the pH of the blood. Kidneys play important roles in other bodily functions, such as releasing the erythropoietin protein, and helping to control blood pressure. Kidne...
