Three Minutes Half Life
528 words
There are 109 known elements, and of those, 19 of
them are artificially produced or synthetic. A
synthetic element is made by bombarding atomic
nuclei with neutrons or other particles. The
element Lawrencium has been made in this manner.
While scientists continue to work to create more
elements, it should be noted that most synthetic
elements are so unstable, that they are of
theoretical value only, and have no known
practical uses. This element was discovered at the
Lawrence Radiation Laborator...

Dissolved oxygen infers to the volume of oxygen
that is contained in water. Oxygen enters water
through photosynthesis and across the water
interface. The amount of oxygen that can be held
by the water depends on the water pressure,
salinity, and temperature. Gas solubility
increases with decreasing temperature; thus colder
water holds more oxygen. A reason why freshwater
holds more oxygen than does saltwater is because
gas solubility increases with decreasing salinity.
When there is a change in...

Chemistry Independent Study: Gas Laws Since the
days of Aristotle, all substances have been
classified into one of three physical states. A
substance having a fixed volume and shape is a
solid. A substance, which has a fixed volume but
not a fixed shape, is a liquid; liquids assume the
shape of their container but do not necessarily
fill it. A substance having neither a fixed shape
nor a fixed volume is a gas; gases assume both the
shape and the volume of their container. The
structures of gases...

Acetic Acid H 3
842 words
In the simple formalism proposed independently by
Bronsted and Lowry in 1923, an acid was defined as
a proton donor and a base was defined as a proton
acceptor. In the simple acid-base reaction shown
below, H 3 O+ is termed a Bronsted Acid, and HO- a
Bronsted Base. In writing organic reaction
mechanisms, the flow of electrons is often shown
using "curved arrows" and in the example shown,
the arrows are designed to show that an unshared
pair of electrons from hydroxide anion moves to
abstract a p...

Urban Sprawl Urban sprawl is the spread of urban
congestion into adjoining suburbs and rural
sections. (Brecher 34) Urban sprawl has become an
issue for concern in the country since 1920. There
was a rapid rate of sub urbanization between the
years 1920 and 1950. Then by the seventies and
eighties, urban sprawl has been curbed to moderate
suburbanization. Urban sprawl has characterized
American growth patterns for the past eighty
years. There has been much controversy surrounding
this hot topic....

Composed Of Particles State Of Density Dimension

The Facts of Life Existence is Truth Everything we
know of is the third dimension, and its
properties. Everything is composed of atoms, and
atoms are composed of smaller particles. All
particles are three dimensional because they have
the dimension of height, the dimension of width,
and the dimension of depth. Air is composed of
particles in a low state of density, water is
composed of particles in a more dense state, and
physical objects are composed of particles in a
high state of density. Thi...

The density of air In this experiment we are to
measure the density of air. It is a quite simple
experiment, you learn how important it is to
measure exact and be aware of the sources of error
when measuring such small quantities. The whole
idea is that you know the mass of a certain volume
of air, and then measure the volume. A digital
scale that shows two decimals measures the first
variable. We simply took a plastic bottle, weighed
it when the lid was open, then with the help of a
compressor,...

Gene Regulation Using the Lac Operon Abstract Gene
regulation in cells has been studied extensively
in both eukaryotic and prokaryotic organisms. Gene
control is employed as a way of saving the cell
energy by only producing those enzymes it needs.
In eukaryotes, genes are regulated so as maintain
levels of cell specificity. In this experiment,
the restriction of the production of the
-galactosidase enzyme in the prokaryote
Escherichia coli can be achieved by employing the
lac operon. This operon...

Population Density Critical Thinking

Exercise 2: Mass Wasting Mass wasting is a
phenomenon that has resulted in over one million
deaths and billions of dollars of damage in its
recorded history. Mass wasting is classified by
the rate at which debris moves down slope. For
instance, rockfalls move at speeds of over
thirty-MPH, while mudslides travel at around
twenty MPH. This field trip explored two
translational slides; one at the Gros Ventre River
in Wyoming, and the other at the Madison River in
Montana. In Wyoming, the slide was ...

Lions Lions are big animals with no fear of
anything. They are harsh predators and will do
anything to kill a prey for food. Some key facts
about lions are that adult males grow
approximately 9 feet from nose to tail. The
females are a lot smaller than the males. Males
usually weigh up to 350 - 550 pounds. The female
lions weigh up to 250 - 300 pounds which is much
smaller than the male lions growth. It takes most
lions 3 to 4 years to sexually mature. The lions
mating patter is non- seasonal wh...

Idoru by william gibson is nothing less than an
awe-inspiring book for me. no other author that i
have come across can inspire one to recreate
visions of reality at the turn of every page.
Gibsons books are all compelling; neuromancer
(1984) needing perhaps a special mention; as this
book single handedly created the cyberpunk genre,
aswell as coining phrases such as cyberspace.
However, as one of his later works (1996), we are
able to find within Idoru's more contemporary
exploration of our worl...

Earths Atmosphere Boiling Point

Neon was discovered in 1898 by British chemists
Sir William Ramsay and Morris W. Travers as a
component of the most volatile fraction of
liquefied crude argon obtained from air. Upon
applying an electric current to it, the chemists
found that it had an orange glow, and they decided
that it was not argon, but rather a new element
altogether. Neon is not a very common element, but
the places it is most abundant in are the earths
atmosphere, and trapped within rocks in the earths
crust. The place w...

QUESTION: What is Angina? And what is the cure?
RESPONSE: Angina refers to the pain arising from
lack of adequate blood supply to the heart muscle.
Typically, it is a crushing pain behind the
breastbone in the center of the chest, brought on
by exertion and relieved by rest. It may at times
radiate to or arise in the left arm, neck, jaw,
left chest, or back. It is frequently accompanied
by sweating, palpitations of the heart, and
generally lasts a matter of minutes. Similar pain
syndromes may be...

Population Density Rural Areas

In Cornwall there is not an even distribution of
people living in Cornwall. But population density
figures say that there are a certain number of
people living in a sq. km. This is because it
gives an average and does not take into account
the large pop. density in cities and the small
pop. densities in rural areas. In places like
Truro there is a large population density, which
is mainly richer. This is because it is the
capitol of Truro and all the large chains want to
put branches there. This...

studying the earths upper atmosphere, observing
animal survival in space flight, and testing
Soviet rocket technology. The launch of the
unmanned Sputnik 1 and of Sputnik 2, which carried
a dog, spurred the United States to invest more
money and resources into its fledgling space
program, initiating a race between the two nations
