chemistry is about the things we need and use in our daily lives-air,water,food,clothing,medicine,dwelling,telecommunication,transportation,fuel,etc.our culure and our environment are somehow shaped by the development of our knowlege of science.chemistry particularly,has made significant contributions to society.

Other chemical products discoverd accidentally included perkin’s dye. Schoenbein’s enplosives,and baekeland’s plastics.these accidetal discoveries,however,cannot be attributed to sheer luck. These people were able to immediately relate their chance observations of possible applications to a given problem because their minds were prepared. They…[Read more]

There is no single method by which scientists solve problems.different people seek solutions to a certain problem in different ways.though some scientists fail to find the solution to a certain problem,they sometimes discover something else of value by chance or serendipity.the word serendipity came from the story the princess of serendip.these…[Read more]

Ask your grandparents if they had used plastic bags and other plasticware when they were your age.suggest solutions to the big polluti0n problem caused by plastics. The chemistry of polymers has greatly advanced.it is n0w possible for chemists to design polymers with different sets of properties to suit a wide range of useful products.
