chemistry is life


chemistry plays an important role in every person’s daily activities from the moment we’re born. 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. Almost anything you do during the course of a normal day involves chemistry in some way. The gas and tires in cars we drive, the makeup we put on our faces, the soaps and cleaners used everyday, burning wood or other fossil fuels, chemistry is all around you each and every day. So definitely CHEMISTRY IS LIFE.

  1. This particular blog post doesn't count as a valid post for the purpose of the assignment. Each post must focus on a particular thing (e.g. chemistry behind foot odour) and talk about its chemistry aspect (of course other aspects are allowed too but not too much please).
