Rate Of Reaction Carbon Dioxide
1,229 words... onward sources, from a textbook, encyclopedia, and preliminary work that I have done in class. I have shown my results on a bar chart and a line graph. On the line graph, I have drawn a curve of best-fit. There were no anomalous results. From my results, and my graph, I have found out that as the temperature of the enzymes (yeast in this case) is increased, the rate of reaction speeds up. However, when the temperature reached a certain point, (about 40 degrees Celsius), the enzymes became de...

Thyroid Gland Pituitary Gland
1,366 wordsAccording to the American Thyroid Association, millions of Americans (especially women) suffer from a thyroid disorder, and many of them dont even know it. In fact, thyroid disorders occur much more often than even many doctors realize. The butterfly-shaped thyroid is in the neck, its two wings wrapped around the windpipe just below the Adams apple. This vitally important gland normally weighs less than an ounce, but it can have an enormous impact on your health. Think of it as your bodys metabo...

Valence Electrons Carbon Dioxide
328 wordsFor my report, I choose to design a ball and stick model for a carbon dioxide molecule. I used the C as the center and an O on each side of the C. For Christmas purposes I colored the C green and the two Os red. To make the letters, I used white out. The sticks that connect the balls are actually cue tips that I have taken the cotton off of. I used glue to make it stick on better and just punched in the stick. The sticks are suppose to be springs and I tried bendable straws that were cut, but th...

Positive And Negative Conduct Electricity
595 wordsElectrolytes are liquids that conduct electricity. Most need to be dissolved into water or another solvent. Battery's have an electrolyte in them, either as a liquid or as a paste. Liquid electrolytes are used in electrolysis, electroplating, and other chemical processes. When electrolytes dissolve they release positive and negative ions. The released ions carry electric charges between electrodes, in the solution. Cations (a positively charged ion that migrates to the cathode, a negative electr...

Acetic Acid H 3
842 wordsIn 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...

Paddle Pop Stick 2 Co 3 Flame
663 wordsExperiments to determine the identity of metals by examining the colour of flame when samples of that metal are heated. The aim of this experiment was to find out whether different metals had different reactions when subjected to the flame of the Bunsen burner. This might then allow the classification and identification of certain metals if they have their own reactions, which will be different coloured flames for this experiment. It was hard for me to predict what would occur during the experim...

Plant Cells E G
840 wordsWater has importance inside cells and externally. This may be because it has interesting chemical and physical properties; it can be found naturally in all three of its states. However its molecules are bonded together by hydrogen bonds, this raises its melting and boiling points, i. e. its boiling point would be - 120 C rather than 100 C. Also because it contains slightly negatively charged oxygen atoms and slightly positively charged hydrogen atoms making it polar. Water has been called a univ...

Orbital Magnetic Dipole Orbital Magnetic Dipole Moment Electron
519 wordsThe Discovery Of The Electron The electron was discovered in 1895 by J. J. Thomson in the form of cathode rays, and was the first elementary particle to be identified. The electron is the lightest known particle which possesses an electric charge. Its rest mass is Me equal> 9. 1 x 10 - 28 g, about 1 / 1836 of the mass of the proton or neutron. The charge of the electron is -e = - 4. 8 x 10 ^- 10 esu tro static unit). The sign of the electrons charge is negative by convention, and that of the equ...

Composed Of Particles State Of Density Dimension
395 wordsThe 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...

Crick has done some amazing work in other fields since his famous work with Watson in the 50 s. Most recently, Crick has begun to address the current hot topic in science: consciousness. Though Crick may or may not make earth-shattering observations in his book, The Astonishing Hypothesis, he at least makes a concise, coge...

Throughout history man has searched for the origins of his existence, both on an outward and inward level, seeking truth and understanding of his world. The first culture to actively explore this idea of philosophy was the Greeks. Because their civilization placed less emphasis on religion and the masses didnt have to constantly answer to religious figures man had t...

Big Bang Theory Hundreds Of Years
896 wordsWhich was came first, the chicken or the egg? One cant come about without the other. So where did the first one come from? This is the question that, people in general as well as scientists, have been pondering for hundreds of years. There are several different beliefs, probably more scientific than Christian, and in this report I will tell you about four of them. Because there are so many scientific theories I will be telling you three of those and one of the Christian. The first theory I will ...

Hydrogen Bomb Chain Reaction
409 wordsThe Hydrogen Bomb The history and workings of this massive bomb Back in 1905 Albert Einstein published his special theory of relativity. According to this theory the relation between mass and energy is expressed by the equation E = mc squared, which states that a given mass (m) is associated with an amount of energy (E) equal to this mass multiplied by the square of the speed of light (Encarta). So years later in 1939 two German chemists took this idea and applied it to a uranium atom, which wou...

Center Of The Galaxy Super Clusters Small
352 wordsThe Milky Way is the place we call home, as well as about 100 billion other stars. It looks very much like other spiral galaxies when viewed from above. There are spiral arms and a nucleus. Viewed from the side, it is about 140, 000 LY in width and the nucleus (core) is about 20, 000 LY tall. The entire galaxy travels at around 900, 000 km / hr . And it takes. 25 x 109 to rotate completly. The Sun can be found rather far from the center of the galaxy, halfway to the edge of visible matter along ...

Uv Radiation Ozone Depletion
993 wordsOur Radiant Planet- Depletion of the Ozone Layer Ozone is a relatively unstable form of molecular oxygen containing three oxygen atoms produced when upper-atmosphere oxygen molecules are split by ultra violet light. Stratospheric ozone is found in a broad band, extending generally from 15 to 35 km above the earth. Although the ozone layer is surprisingly thin, it acts as a protective shield to the earth, as it filters out most of the harmful solar ultraviolet radiation (in particular UV-B) that ...

Neutron Star Black Hole
559 wordsBlack holes by supernova Firstly, a black hole isnt really a hole at all, but thats the easiest way to think of its effects on the rest of the universe. Take a star thats at least thirty times larger than our sun and make it explode (called a supernova). Stars do that at the end of their lifetime, sometimes leaving a remnant of the violent explosion. The nature of the remnant depends on its mass. If the remnant is less than 1. 4 solar masses, it will become a white dwarf, a kind of hot dead star...

Splitting Into Cellular Atoms Splitting Into Cellular People
368 wordsSpoon River Thomas Rhodes talks about how the people in Spoon River could have prevented their hard times. He compared people in Spoon River to navigators and sailors because they found with all their boasted wisdom how hard at the last it is to keep the soul from splitting into cellular atoms. He also says that seekers of earths treasures are self-contained and harmonized even to the end. In this poem you are not told what Thomas does for a living, but it is implied that Thomas is a bank owner ...
