CHEMISTRY FORM ONE REVIEW

Introduction To Chemistry

When you were in primary school, you used to learn science as a single
subject. At this level of study, the subject will be broken up into three related subjects, namely Chemistry, Biology and Physics.
The three subjects are closely related. You will require the knowledge of one subject to study the other. For example, you will apply the knowledge of chemistry to study different chemical reactions that take place in the
body for studying biology of the human body, etc. Likewise as a
biologist, you will need the knowledge of physics to study movements of
different limbs of the body, etc.
Therefore, these few examples show how
the three subjects are interdependent. Chemistry is usually studied
along with other related subjects such as biology, physics, earth
sciences and mathematics. A person studying science is called a scientist. A scientist specialized in the study of chemistry is called a chemist.
The Concept of Chemistry
Explain the concept of Chemistry
Chemistry
is a branch of science that deals with the study of nature, properties
and composition of matter. Matter can be defined as anything that has
weight or mass and can occupy space. Therefore, in chemistry we study
materials that make up the earth and universe. These range from living
to non-living materials. We apply the knowledge of chemistry to study
the composition, behaviour and nature of materials around us. This study
enables us to make the best use of these materials to improve our
welfare.
Materials Objects Made by Application of Chemistry
Mention materials objects made by application of chemistry
Chemistry
is such an important subject that it is applied in other fields such as
agriculture, manufacturing, medicine, processing and food industries,
education, cosmetics and home care industries, etc. All these industries
are responsible for the production of materials that we need to support
and hence improve our lives. Materials made by the application of
chemistry knowledge include soap, chalk, shoes, clothes, petroleum
products, alcoholic and non-alcoholic beverages, cosmetics, drugs, and
many others. Can you mention some of the materials made by the
application of chemistry knowledge?
This,
therefore, means that chemistry is applied in factories, homes,
hospitals, pharmacies, research centers, higher learning institutions,
etc.
Many
products made by the application of chemistry in industry are all
around us. Some of these materials are summarized in the table:
Some products made by application of chemistry
Field where applied Examples of products
Medicine Drugs, vaccines, nutritional supplements
Agriculture Agro-chemicals ( fertilizers, pesticides, herbicides, acaricides), animal drugs and vaccines, animal feed and supplements
Manufacturing industry Vehicles, cement, plastics, chemicals, paints, iron sheets, vanishes, glue
Food and beverage industry Soft and alcoholic drinks, baked food, canned food, spices, cooking oil, salt
Home care and cosmetics industry Cosmetics, detergents, toothpaste, shoe polish, insecticides, antiseptics, disinfectants
Transport Fuels, lubricants, oil, grease, tar, coolants, tyres
Textile industry Clothes, dyes, bleaches, wax, threads
Leather industry Shoes, handbags, belts, leather articles
