From the foods we eat and the medicines we take to the products we regularly use, our lives are inextricably linked to chemicals and their operating principles.
Chemistry is everywhere. The air we breathe, the ground we stand on, the seas we sail, and the variety of living things including our own bodies; all these are made of substances that we call chemicals. These chemicals interact with one another, and, in many cases, these interactions produce new substances through processes known as chemical reactions.Over time, in high school I have learned much about chemicals and have mastered numerous chemical reactions, giving me the ability to modify existing substances and synthesize new ones. Consequently, chemist have created a whole new realm of materials such as those used in paints, plastics, textiles, pharmaceuticals, soaps, cosmetics, and more. Thus chemistry has provided an important foundation for our modern technological world.
In what ways do we observe the operation of chemical principles in our everyday lives?Let us consider a few examples from the video that help illustrate our connections to chemistry. The simple fact is that chemistry plays an important role in every person's daily activities from the moment we are born. So what role does chemistry really plays in everyday life? Well, this involvement usually begins first thing each morning. Most people wake up to an alarm or radio. These common household items contain batteries, which make them very chemically dependent.
These batteries contain positive and negative electrodes.The positive electrode consists of a carbon rod surrounded by a mixture of carbon and manganese dioxide. The negative electrode is made of zinc. Chemistry plays an important role in the discovery and understanding of materials contained in these and many other common household items. Things like household cleaners and water purification systems are vitally dependent on chemistry.
Without chemistry something as simple as scrubbing a toilet without fear of severe burns or small explosions might not be possible.Even the gas and tires in cars we drive, the makeup we put on our faces, the soaps and cleaners used every day, burning wood or other fossil fuels, chemistry is all around you each and every day. Chemistry is really an amazing subject and works hand in hand with all the other sciences to make things work. According to Don Showalter he stated that “each of these reactions between substances illustrates a concept of the way matter behaves.
” According to Roald Hoffmann “matter is neither created nor destroyed.Research and deduce from your findings which use of metals came first- was it for weaponry or jewelry From my research that I have done there is no historical documentation, but the most likely metals are copper and gold because they are both comparatively easy to find as natural ores, and are both soft enough to use without forging equipment. Both metals were used by many ancient cultures for jewelry and decorative uses; copper was also used for simple tools.Copper is perhaps one of the most important elements for mankind, both due to its multiple uses and to its capacity to replace iron in many cases.
Starting with making objects out of copper and continuing, as mankind progressed, with its use as a good electricity conductor and building material, copper was part of everyday life ever since the copper age. Even today’s world, despite new discoveries that brought about artificially made compounds and alloys, copper remains an important element still significantly used in practice.
