- 4433: Rates of Reaction
- ... an example of a slow reaction is rusting. In any reaction, reactants chemical reactionsฎ products. We can measure reactions in two ways: 1) Continuous:- Start the experiment and watch it happen; you can use a computer logging system to monitor it. I.e. Watching a colour fade or increase. 2) Discontinuous:- Do the experiments and take readings/ samples from the experiment at different times, then analyse the readings/samples to see ...
- 4434: Oxygen
- ... the SPINELS and the PEROVSKITES are studied extensively because of their interesting magnetic and electrical properties. Examples of important ternary oxides are the magnetic FERRITES, whose magnetic properties can be tailored, making them useful in computer memory units. The ferrites are prepared by firing compacted mixtures of iron oxide and one or more metal oxides (such as those of nickel, copper, zinc, magnesium, and manganese). Also of importance in inorganic chemistry ...
- 4435: Nuclear Power: Cons
- ... The accident is an awful reminder that and explosion may not be only a freak occurrence. It so happens that it may be caused by other errors such as human blunder, low water supply or computer glitch, any misfunction may cause horrific problems. The Ukraine poisoned western Russia and almost all of Europe with the nuclear explosion at Chernobyl. Within the first six days, radiation swept across Europe. Radiation levels were ...
- 4436: Determining the Ratio of Circumference to Diameter of a Circle
- ... percentage error for all of the objects measured. The next step was to graph the results. I was able to do this very easily with spreadsheet. I typed in all of my data and the computer gave me a nice scatter block graph. I also made a graph by hand. I set up the scale by taking the number of blocks up the side of my graph and dividing them by ...
- 4437: The Chlorine Debate: How White Do You Want It?
- ... chlorine and chlorine-based products whenever we drink a glass of water, buy food wrapped in plastic, purchase produce in the supermarket, pour bleach into a washing machine, have a prescription filled, print out a computer document like this one, or even drive a car. (Abelson 94) Chlorine, a member of the halogen (salt-forming) group of metallic elements, was first made by Swedish chemist Carl Wilhelm Scheele in 1774, who ...
- 4438: Analytical Chemistry
- ... of the methods currently used are of relatively recent origin and employ sophisticated instruments to measure physical properties of molecules, atoms, and ions. Such instruments have been made possible by spectacular advances in electronics, including computer and microprocessor development. Instrumental measurements can sometimes be carried out without separating the constituents of interest from the rest of the sample, but often the instrumental measurement is the final step following separation of the ...
- 4439: UFOs
- ... roof, approximately two-hundred fifty to five-hundred feet high. The red glow was coming from beneath the object, about center. It appeared as a stream of light coming from inside a hole (Huyghe "UFO Crime Lab" 60)." Many UFOs are described such as this. Is it a UFO or something else? Remember, a UFO is only a UFO if not explained. "On the same day, but at 11:50 A ...
- 4440: BLACK HOLES
- ... telescope has just recently found what many astronomers believe to be a black hole, after being focused on an star orbiting empty space. Several picture were sent back to Earth from the telescope showing many computer enhanced pictures of various radiation fluctuations and other diverse types of readings that could be read from the area in which the black hole is suspected to be in. Several diagrams were made showing how ...
