Examples of chemistry

Chemistry is the science of materials, in terms of composition, structure, and properties. Also study the changes that matter undergoes, which can be caused by chemical reactions or by the intervention of energy.

Chemistry opens in different specialties:
  • Inorganic chemistry: Refers to all elements and compounds with exceptions of carbon derivatives.
  • Organic Chemistry: Study of carbon compounds and derivatives.
  • Phytochemistry: Studies the relationship between matter and energy in a reaction.
  • Analytical chemistry: Establishes methods and techniques to analyze the chemical composition of substances.
  • Biochemistry: Study the chemical reactions that take place in living organisms.

Although it is a complex discipline that requires a long preparation for its understanding and the advancement of knowledge, applications of chemistry can be observed in everyday life, since its application has improved our quality of life thanks to its combination with technology and technology. industry.

Furthermore, chemical reactions occur in nature itself, in our own bodies, and in everything around us.


  1. The pesticides are chemicals that are used to fumigate crops where our food is obtained.
  2. The food give us energy through chemical reactions within the cells.
  3. Each type of food has a different chemical composition, offering different contributions to the body.
  4. The helium is used to inflate balloons.
  5. The photosynthesis is the chemical process by which plants synthesize (produce) saccharides.
  6. In drinking water it includes various chemical substances such as mineral salts.
  7. Chemicals in suspension in the air known as smog , which harm our health.
  8. Different colorants are chemical compounds used to make industrial foods more attractive.
  9. Foods also enhance or change their knowledge through chemical compounds called flavorings. Flavorings can either mimic the flavor of a natural product or develop an unknown flavor.
  10. The sulfur is used in tire repair.
  11. The chlorine is used for bleaching clothes, disinfecting surfaces and in small amounts also for water purification.


  1. The detergents are chemicals that are used to wash objects and our homes.
  2. The dyes are chemically developed to give color to the fabrics that make up clothing and other items for daily use.
  3. Food is fermented and can no longer be safely consumed.
  4. Chemical substances known as preservatives are used to prevent the fermentation of food industrially.
  5. The means of transport use different substances derived from oil that undergo chemical changes within their engines.
  6. Chemical analysis of tobacco smoke identified that it contains ammonia, carbon dioxide, carbon monoxide, propane, methane, acetone, hydrogen cyanide, and other carcinogens. This discovery alerted us to the need to protect passive smokers.
  7. We usually use multiple plastic elements. Plastic is a chemical product obtained by the polymerization (multiplication) of long-chain carbon atoms, of petroleum-derived compounds.
  8. The leather is also chemically treated with compounds that prevent decomposition and can also give different colors to the natural.
  9. Different chemical substances allow the potability of water to be identified, through the identification of bacteria and inorganic substances.
  10. The so-called ” eco-leather” or synthetic leather is a product of polyurethane, a chemical that is obtained by the condensation of hydroxyl bases (alkaline molecules) and diisocyanates (highly reactive chemical compounds).


  1. The Neon is used for fluorescent lights.
  2. The breath is an exchange of substances in the lungs, studied by biochemistry.
  3. The diseases are treated with chemicals (drugs) that eliminate the microorganisms that cause them .
  4. The different mineral salts are used by the body to support all its vital processes.
  5. Knowledge of smog and its components allows the development of chemical substances ( cosmetics ) that counteract its negative effects on our skin.
  6. The forensic chemistry studies the organic and inorganic compounds found at crime scenes, working with police investigations.
  7. Even the most basic foods like salt are chemical compounds: salt is made up of cations (positively charged ions) and anions (negatively charged ions) through ionic bonds.
  8. Each part of our body has a specific composition that it needs to maintain to stay healthy. For example, nails are a compound of amino acids and different inorganic substances like calcium and sulfur.
  9. The chemical composition of blood includes sugars, amino acids, sodium, potassium, chloride, and bicarbonate.
