Acid Rain
Acid Rain As the century past, the industrial society kept advancing. However, many advantages of the industrial society brings us also has a down side. One of the adverse effects of industrialization is acid deposition due to power plant, fossil fuel and automobile emissions. Acid rain is the popular term but the scientists prefer the term acid deposition. Acid rain can have adverse effects on the environment by damaging forests or by lowering the pH of the lakes and making the water too acidic

The Caribbean Sea is geologically separate from the North and South Am
The Caribbean Sea is geologically separate from the North and South American continents. Together with Central America, it forms a tectonic plate which is moving W at about 4 cm a year. At the same time, the North American and South American plates, which lie under the continents and the eastern half of the Atlantic Ocean, are moving W. Most of the Caribbean islands are close to the boundaries of the Caribbean plate. Plate boundaries are geologically active; this is why most parts of the Caribb

Rates Of Reaction Aim: To investigate the effect of the concentration of Hydrochloric acid on the rate of reaction between Hydrochloric acid and Calcium Carbonate. Background: The rate of reactions between two substances is dependent on many factors or variables: 1. Change in temperature 2. Surface area of solid substance, 3. Concentration of the acid, 4. Volume of Acid used. While doing my experiment, I must remember to keep all of my variables the same. This will make it a fair test. For examp

Carbon is one of the most important chemical elements Industry uses it
Carbon is one of the most important chemical elements. Industry uses it in a wide variety of products, and all living things are based on carbon. Without carbon, life would be impossible! Yet carbon makes up less than 0.03 percent of the earth’s crust. Pure carbon exists in nature in the form of diamonds, and in graphite. Both forms are pure carbon with different crystal structures. Another form of pure carbon, called amorphous carbon, consists of graphite-like particles too tiny to see without

RUBIDIUM
RUBIDIUM The 37th Element Rubidium is located between potassium and cesium in the first Group on the Periodic Table. It’s atomic number is 37and its atomic mass is 85.4678. In French and German it is rubidium, in Italian and Spanish it is rubidio. History and General Facts Rubidium was discovered spectroscopically in1861 by Robert Bunsen and Gustav Kirchhoff in Germany. They experimented with spectral lines of light, now called spectroscopy. They noticed that, when heated or burned, different e

Magnesium
Magnesium Magnesium is one of the alkaline-earth metals of main group IIa in the periodic table. Magnesium is a grayish-white metal. Normally magnesium is covered with a layer of oxide, MgO, that protects magnesium from air and water. Magnesium is an important element for plant and animal life. Chlorophylls depend greatly on it.Sir Humphrey Davy discovered magnesium in 1775 at England. It was dicovered when he evaporated magnesium amalgam by mixing a moist magnesia and mercuric oxide.

How Much Weight Can Eggs Hold
How Much Weight Can Eggs Hold??? Our project is on how much weight can eggs hold. So we first researched the common egg itself. The most important part of an egg is the germ. You can also call it the nucleus. Next is the shell. The shell is made out of two layers. One of the layers is called the mammilary layer. The shell membrane is located just inside the shell. The shell is mostly made up of calcium carbonate. Now we go to the egg white. The white of an egg is made up of four parts. The four

Have you ever wonderedwhy water sometimes appears blue and sometimes g
Have you ever wondered….why water sometimes appears blue and sometimes green? Why lobsters change colour when you cook them? Why the colours of a soap bubble shift and change colour with the breeze? Why the sky is blue, why the grass green and why the robin has a red breast? It is often thought that the brightest colours can only come from artificial chemicals or ingredients. But the truly brightest of all colours can be seen in nature. In the animals, the land and the sky. The first example of

Whether we realize it or not sensory receptors play a big part in our
Whether we realize it or not, sensory receptors play a big part in our everyday life. Without the ability to sense our outside surroundings, we would quickly be put at a disadvantage to those around us. It is often taken for granted, but every facet of life depends on the ability to sense things. From the time when we first hear our alarm clock in the morning, to getting our balance once we get out of bed, then having to see the way to get to the bathroom, and even being able to taste and smell
Calcium
Calcium
Calcium Calcium is a member of the Alkaline Earth metals. In cosmic abundance it is ranked thirteenth, and ranked fifth on Earth, making up 3.64% of the earth’s crust (Microsoft Bookshelf). Total Calcium contents of surface soils are very low compared to its relative content in the earth’s crust and compared to the contents of most of the other major elements that make up the soil. Calcium is a light, malleable, silver-white metal. Calcium is not found in a free, uncombined state in nature beca

Gaia and Plate Tectonics
Gaia and Plate Tectonics Geologists and biologists have traditionally thought of life as having adapted to changes in the environmental conditions over time, but a new view of the earth derived from the Gaia theory has emerged. Many scientists now look at the entire earth as an organism, where living and nonliving matter evolve together maintaining an environment nearly ideal for life. The Gaia theory maintains that soon after the formation of life, and organisms began to change the environment,

Chemical Reactions
Chemical Reactions Chemical reactions are the heart of chemistry. People have always known that they exist. The Ancient Greeks were the firsts to speculate on the composition of matter. They thought that it was possible that individual particles made up matter. Later, in the Seventeenth Century, a German chemist named Georg Ernst Stahl was the first to postulate on chemical reaction, specifically, combustion. He said that a substance called phlogiston escaped into the air from all substances dur

Pop and its Problem
Pop and its Problem
Pop and its Problem Did you know the adult person drinks about 2-3 cans of pop a day. Teenagers drink about 3-4 cans a day. But drinking too much can be a real problem because the dangers seem hidden. Pop may seem like a good combination with pizza or other salty or fatty foods because the salt in the food makes your tongue crave sweetness. The sweetness of the pop compensates the urge and it makes you able to eat more fatty food if you drink pop. The sugar in the pop is also extremely bad for
