Chemistry

WHAT WE HAVE LEARNT Medicines, insecticides, textiles and food materials that we use in daily life are chemical substances. Cement is used for building purposes becauses it has the ability to 'set' when mixed with water. Natural rubber is the exudation from rubber plants. Polymers are very large molecules formed by the combination of small molecules.

operties development make new materials and to control their different proper ties. The development of chemistry made this progress possible. The contribution of chemistry to like, agriculture industries, care food industry habitat, fields like , agriculture , industries, health care , food industr y, habita t, transport and research has been invaluable. Through chemical processes that scientists develop chemistry comes up every day with answers to ever increasing needs. increasing human needs.
So what role does chemistry really play 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.
Next, though it isn’t widely known, chemistry is also heavily involved with the manufacturing of things such as makeup and soap. Each time you bathe you are witnessing chemistry at work. Chemicals such as cetyl alcohol and propylene glycol are typical ingredients in the soap used to wash your hair and skin....
