The Importance of Chemistry in Everyday Life - The Importance of Chemistry in Everyday Life During laboratory technique 1 we learned how to separate insoluble liquids from solids by means of filtration, and how to separate a dissolved solid from a liquid by means of evaporation. I have often asked myself the importance of some of the required classes in my schedule and how they can relate to everyday life. I believe in the saying that if you don’t use it you will lose it, meaning that if the concepts I learn cannot be applied to something that I will remember on a daily basis then the possibilities of me not remembering them at all are greater....   [tags: Papers] 398 words

Physics chemistry - ATHENS, Ohio -- Today's computers and other technological gizmos operate on electronic charges, but researchers predict that a new generation of smaller, faster, more efficient devices could be developed based on another scientific concept -- electronic "spin." The problem, however, is that researchers have found it challenging to control or predict spin – which keeps practical applications out of reach. But physicists in Europe, California and at Ohio University now have found a way to manipulate the spin of an electron with a jolt of voltage from a battery, according to research findings published in the recent issue of the journal Physical Review Letters....   [tags: essays research papers] 517 words

The Key Minds That Made Chemistry - ... This was the man who invented the technique of chemical formula notation. Which played a huge part in our classroom lately. Jons was very successful electrochemist, who was rivaled by Humphry Davy, yet it doesn’t seem like much of a rivalry since Jons was much more systematic about accomplishing his experiments. Another huge discovery he mad was the law of constant proportions, which states “the elements in inorganic substances are bound together in definite proportions by weight.” What makes this discovery interesting is that he came about this while doing experiments in an effort to put together a textbook for his students....   [tags: law, formula, periodic, table, prizes] 822 words

Chemistry Experiment on the Reaction of Different Metals When Exposed to Acid - Before the experiment, I wrote down a prediction. My hypothesis towards the experiment was that magnesium would have a bigger reaction with the acids. The reactivity of an element depends on its ability to gain or loose electrons which are used for bonding. The more reactive an element, the more easily it will combine with others. From this information, I know that magnesium has a stronger ability to gain or loose electrons which makes the metal more reactive. I gathered together four different metals and acid compounds which all reacted with one of the elements in the past, for example, Iron Sulphate (FeSO4) contain iron....   [tags: chemistry lab] 856 words

chemistry (ocean) - What is an iceberg. Why are they blue or green. An iceberg is a large floating block of freshwater ice that has broken off the edge of a glacier and been carried out to sea; about 90% of its mass lies under the water. The bluish streaks of clear, bubble free ice often seen in icebergs results from the refreezing of melt water which fills crevasses formed in the glacier as it creeps over land. The ice is blue because of the natural light scattering characteristics of pure ice. Occasionally airborne dust or dirt eroded from land ends up on the glacier surface eventually forming a noticeably darkened brown or black layer (in any orientation) within the ice of a floating iceberg....   [tags: essays research papers] 872 words

Bohr's Atomic Model - ... Why couldn’t the electron exist in a limitless number of orbitals with slightly different energies (pg.104, line 4). Scientists began changing their view on the nature of the electron. They eventually discovered, through investigation of the hydrogen’s emission-line spectrum, that light could behave as both a wave and particle (pg.104, line 9). This discovery caused Dr. Brogile to point out that in many ways the behavior of electron in Bohr’s quantified orbits was similar to the known behavior of waves (pg.104, line 14)....   [tags: history of chemistry] 877 words
