... number of magnesium is 12. Magnesium(s) + Hydrochloric acid(aq) = Magnesium Chloride(aq) + Hydrogen(g) Mg + 2HCl = MgCl2 + H2 In the reaction when the magnesium hits the acid when dropped in, it fisses and then disappears giving of hydrogen as it fisses and it leaves behind a solution of hydrogen chloride. The activation energy of a particle is increased with heat. The particles which have to have the activation energy are those particles which are moving, in the case of magnesium and hydrochloric acid, it is the hydrochloric acid particles which have to have the activation energy because they are the ones that are moving and bombarding the ...

... of 5,000,000 C%. The kinetic energy is then extracted by passing through a magnetic field. This produces a strong voltage. The only disadvantages to this power source is the lack of knowledge we have for it. Hopefully, within time, we will learn about this new energy source so we can use it to power the future. Fusion Power Fusion Power is probably the biggest known Alternate Energy Resource. Fusion is the joining of the nuclei of two atoms to form the nucleus of a heavier element. It occurs mostly with hydrogen and other light elements. Fusion reactions, also called thermonuclear reactions, release a great deal of energy. Scientists are still con ...

... and late afternoon, when the light is coming at more of an angle and the water stress is not as severe (Donahue and Vogelmann). Under these conditions the lamina of the leaf is within less than 15° from the normal to the sun. Many plants that exhibit diaheliotropic movements also show paraheliotropic response as well. Paraheliotropism minimizes water loss by reducing the amount of light absorbed by the leaves; the leaves orient themselves parallel to the sun’s rays. Plants that exhibit paraheliotropic behavior usually do so at midday, when the sun’s rays are perpendicular to the ground. This reorientation takes place only in leaves of plants that are capable ...

... center of the storm. The system moved west-northwest at 16 mph and forecasters expected Floyd to continue along this track for 72 hours. Floyd was in an area very favorable for development and satellite images indicated the system was strengthening. The center of the system was not yet well defined, but forecasters believed Floyd could reach major hurricane strength with maximum sustained winds of 112 mph or more after 72 hours. Tropical Storm Floyd Continues to Intensify Washington, September 9, 1999 -- The National Hurricane Center (NHC) reported that Tropical Storm Floyd was located about 450 miles east of the Leeward Islands. The ...

... main problem with the decaying ozone layer consists of people being careless. Many times, the chemicals released into the air by people drift into the ozone and form harmful chemical bonds with ozone molecules. One example would be chlorofluorocarbons or CFC's. CFC's were commonly found in spray cans during the early 1970's but were invented in the 1920's. They contain chlorine, fluorine, and carbon atoms which all form bonds with the rare ozone molecules. A few more products with CFC's are coolants for refrigerators and air conditioners, foam products, such as cups, and insulation for houses. Considering that ozone molecules are so rare, it is extreme ...

... other livestock. More than half the rual families in Central America-35 million people-are now landless or own too litle land to support themselves. Cattle are also a major cause of desertification around the planet. Today about 1.3 billion cattle are trampling and stripping much of the vegetative cover from the earth's remaining grasslands. Each animal eats its way through 900 pounds of vegetation a month. Without plants to anchor the soil, absorb the water, and recycle the nutrients, the land has become increasingly vulnerable to wind and water erosion. More than 60 percent of the world's rangeland has been damaged by overgrazing during the past half century ...

... constructed from existing information are broadly based, pulling information from several sources and adapting it for target audiences. Such articles tackle general biomedical issues and convey the information to an audience that, for the most part, lack a high level of scientific knowledge. To make the information more understandable for the target audience, authors substitute in less complex vocabulary words, summarize difficult concepts, and often utilize attractive visual aids. Authors strive to communicate issues to audiences of varying levels of education. In order to accomplish this effectively, authors adapt their work in a format that expresses their conce ...

... The legs are straight in infantry but when a child. He begins walking they develop a knock-knee position. When the child continues to walk legs begin to have a bowed-leg look. Occasionally, these curvatures are fixed. As the child continues to walk the kyphosis disappears and the back assumes a lordotic posture. If a delay in child’s walking occurs, the spine should be monitored closely for signs of gibbous formation. In infancy, hypercephalus can occur. Infants head circumference should be monitored close . Monthly checks of head circumference must be monitored. Radiologic studies are indicated if head circumference raises to disproportionately, or if symptoms of ...

... with hemp produces as much pulp as 4.1 acres of trees. Farming hemp at such a fast rate is the key to providing large enough amounts of raw biomass at costs low enough to enable cellulose (the hydrocarbon provider necessary for fuel production) to recapture lost markets. This versatility has led people to believe it is the only biomass resource capable of making America energy independent. There is only one catch: the federal government prohibited the growth of hemp in 1938. There were also theories that the major energy industries of the late 30s collaborated to ensure a petroleum-based energy market. Regardless of laws, let us consider hypotheticals. F ...
