Introduction to Chemistry
Original Transformations and First Learning: In parallel with the practice driven by the need to advantageously transform the forms of materials, these ancestors of man had to notice the numerous transformations that alter the nature of materials in their environment. Fire represented a source of heat and light, and a means of protection against predators.
Advances in the Ancient World: The techniques involved in the recognition of minerals, the process of reduction to metals and their smelting, the forging and tempering of metals have had such an impact on social progress that historians have periodized stages of development as the Copper, Bronze and Iron Age.
Middle Ages and Alchemy: The influence of Christianity on the slow development of scientific knowledge throughout this period is explained taking into account the new patterns of thought that this religion carried and the interests that the new structure of ecclesiastical power defended
Pre-Chemical Knowledge from Greece to Rome: It can be noted that in the culture of ancient Greece not even the first attempts at experimental study of chemical transformations were developed.
Chemical Products in the Workplace:
Chemistry in the Company: Exposure to chemicals can cause or contribute to many serious health effects such as heart disease, kidney and lung damage, sterility, cancer, burns and rashes.
Chemistry in the Food Industry: Food industries like MERK have developed new products such as flavoids, folates and polyunsaturated fatty acids (omega 3) for functional foods and food supplements.
Chemistry in the Footwear Industry: These concerns about toxic substances in contract factories have been continually raised with companies like Nike. Factories will have three months from the date of the final report to "make corrections that make the air quality equal to that required by OHSA (the US Occupational Safety and Health Administration).
Chemistry in Other Industries: Many of the consumer products that we regularly use or come in contact with every day, at home or in the office, contain chemical additives.
Chemical substances
Chemical substances depending on their characteristics
Physicochemical: Oxidizing substances Those that in contact with other substances, especially flammable ones, produce a strongly exothermic reaction.
Introduction to Chemical Substances: The development of regulation on the handling of chemical substances is associated with the development of the pharmaceutical industry; In 1930 the so-called "therapeutic revolution" began with the introduction of sulfa drugs as chemotherapeutic substances for the treatment of various infectious diseases.
General information on dangerous chemical substances: Some of the physical and chemical properties of substances can favor their movement from the sources that generate them to the possible receptors.
Adequate Management of Chemical Substances: Since our country accepts that it has responsibilities, in the first instance before society, the environment and natural resources, it has fully affirmed in international forums its commitment to environmental protection, recognizing that ecological and environmental problems they become a danger to society as a whole, which is why their solution necessarily requires cooperation
Fundamental concepts of Chemical Science:
Chemistry Concept; From Alchemy, the forerunner of Chemistry, which intended to manufacture the Philosopher's Stone and the
elixir of eternal youth
Generally, the atoms combine in fixed proportions to give molecules. For example, two hydrogen atoms combine with one oxygen atom to form a water molecule.
The States of Matter: General or extensive: all matter has them but they do not allow us to identify it. Its properties are: weight, mass, volume, porosity, impenetrability and hardness. The specific or intensive: they allow to identify the matter.
Characteristics of the States of Matter: It can be metals: positive ions surrounded by electrons, which are good conductors of electric current, hard and have high melting and boiling points, such as copper, gold, silver.
