Being around big happy plants all the time helps people in the south happy by giving them something to take their mind off of life for a while. Garden Geraniums may reach the size of a bush in warm, dry climates (Garden Geranium 1). Again, the bright colored flowers make any bouquet of flowers complete. It is very hard to get any Geraniums to grow in short and cold growing seasons, like in the Pacific Northwest. It was very easy to grow and pick the beautiful flowers in the south. Wisteria is in the legume family of woody, climbing plants. The best know Wisteria are Chinese, but American are just ....

Air Pollution
788 Words - 3 Pages.... and nitrogen oxides. Nitrogen oxides can react with hydrocarbons in the prescence of sunlight to produce a form of oxygen called o-zone. O-zone(O³) is the chief component of photochemical smog, which is a common form of . Fuel combustion for heating and cooling homes,offices,buildings, and factories contribute significantly to . Electric power plants that burn coal or oil in also releases pollutants into the atmosphere. The major pollutants from these source are nitrogen- oxides, sulfur-oxides, and carbon dioxide.
The rapid growth of population and industry, and the increased use of automobiles and airplanes has made a very serious and complicated problem ....

The Year 2000 Bug
2317 Words - 9 Pages.... will give us a better look at what may happen.
In order to understand the Y2K bug we must first understand what it is. For many years electronic storage was very expensive. In the early days of computing a Megabyte or a million bytes of information could have cost up to $100,000 to store electronically. This same amount of information storage can now cost around ten cents. Because of this expensive storage limitation code written for these older computers was compressed in any way possible. One way to cut down the size of code was to compress dates to a format only six characters long. So instead of April 14 1999 the date would be compressed to 4/14/99. At the time ....

Ozone
841 Words - 4 Pages.... absorbs harmful ultraviolet radiation in the upper atmosphere, and
protects humans from skin cancer. But ozone is also the main ingredient of smog,
and causes serious health effects and forest and crop damage in the lower
atmosphere. Ozone is formed through the chemical reaction of volatile organic
compounds and nitrogen dioxide, in the atmosphere, in the presence of sunlight.
This reaction is called a photochemical reaction, because sunlight is required.
The product is known as smog. The notorious brownish color of smog is due to
nitrogen dioxide of the mixture. Increased temperature stimulate the reaction,
which is why ozone conditions are worse in the summer. It ....

Intermolecular Bonding Essay
1586 Words - 6 Pages.... ion that is
isoelectronic with the nearest noble gas., the substance is held together by
electrostatic forces between the ions. The tendency for these ions to be formed
by elements is corespondent to the octet rule, when atoms react,, they tend to
do so in such a way that they attain an outer shell containing eight electrons.
The factors that effect the formation of ions are ionization energy, electron
affinity, lattice energy.
Figure 1
The transfer of electrons involved in the formation of (a) sodium chloride and
(b) calcium fluoride. Each atom forms an ion with an outer shell containing
eight electrons.
For many elements, compounds cannot be formed by the production of ....

The Dangers Of Nuclear "Progress"
610 Words - 3 Pages.... to far.
The dropping of the atomic bombs on Japan should have caused alarms
to sound in people's heads…"Danger, danger!" Just one of these bombs has
the ability to wipe out an entire country. The United States did make an
attempt after World War II at eliminating nuclear proliferation by
proposing the Baruch Plan in the United Nations. This proposal stated that
all nuclear technology and materials be placed under international
ownership and that all nuclear weapons be destroyed. However, the Soviet
Union feared that the United States would always have a military advantage
if they gave up their plans for building a nuclear device and, therefore,
rejected the p ....
