Question

merits and demerits of chemistry in our daily life

Answer 1

The role of chemistry in our lives cannot ignore any cost as it involves everywhere in our surroundings. It helps us understand the working of different things and provides new ways of making our lives better. It is involved in the making of most of the things we use every day.

Few advantages of chemistry in our daily life are as follows:

We can manufacture new materials which make our lives easier such as polythene is a polymer of ethene. It is used to wear and for the formation of different machine parts, or tools.
Chemistry is also involved in the synthesis of new medications which are used for the treatment of different diseases.
Similarly it involves the creation of new ceramics which absorb heat in a way and allows them to withstand even at high temperatures. 

Chemistry provides an update about the components of our food, bodies, and our surroundings.
It can also give information about adulteration in food stuff and helps us to be healthy.

Disadvantages of chemistry.
 No doubt, the aim of scientists is always to improve the quality of human life and other living bodies. But sometimes these new inventions can be harmful to the living bodies and their environment such as any introduction or removal of the chemical substance in our environment can change the composition of it and affect the social, living organisms, or earth-wide.
Many chemical substances such as DDT, CFCs etc. are very harmful to our environment but are widely used by today’s generation to make their life comfortable. 

Other disadvantages of it are hormone replacement therapy and the Bhopal Disaster. The chemical analysis processes easiest, fastest approach is the EDAX capability.  
There are several advanced technologies which are used for the treatment of serious diseases such as X-ray analysis, chemotherapy etc. The chemical analysis is a fast process which can be done by seeing the phase and morphology of the sample.  But these techniques are considered as semi-quantitative which can be detected the element minimum till Na. These can be detected till the lightest element boron. The precision drops with increasing the atomic weight of the elements.
