Basics concepts of Chemistry. Metals and Non-Metals. Watch Chapter-wise Videos. Chapter 1 - Chemical Reactions and Equations 17 Lectures. What are the topics we are going to learn in chapter chemical reactions and equations? Watch Now! What are the various changes that happen around us? What is radioactive change? What is chemical reaction? When does the chemical reaction happen? What are the types of chemical reactions?The history of chemistry represents a time span from ancient history to the present.
By BC, civilizations used technologies that would eventually form the basis of the various branches of chemistry. Examples include the discovery of fire, extracting metals from oresmaking pottery and glazes, fermenting beer and wineextracting chemicals from plants for medicine and perfumerendering fat into soapmaking glassand making alloys like bronze.
The protoscience of chemistry, alchemywas unsuccessful in explaining the nature of matter and its transformations. However, by performing experiments and recording the results, alchemists set the stage for modern chemistry. The distinction began to emerge when a clear differentiation was made between chemistry and alchemy by Robert Boyle in his work The Sceptical Chymist While both alchemy and chemistry are concerned with matter and its transformations, chemists are seen as applying scientific method to their work.
The history of chemistry is intertwined with the history of thermodynamicsespecially through the work of Willard Gibbs. A ,year-old ochre -processing workshop was found at Blombos Cave in South Africa. It indicates that early humans had an elementary knowledge of chemistry. Paintings drawn by early humans consisting of early humans mixing animal blood with other liquids found on cave walls also indicate a small knowledge of chemistry.
The earliest recorded metal employed by humans seems to be goldwhich can be found free or "native". Small amounts of natural gold have been found in Spanish caves used during the late Paleolithic period, around 40, BC. Silvercoppertin and meteoric iron can also be found native, allowing a limited amount of metalworking in ancient cultures.

Arguably the first chemical reaction used in a controlled manner was fire. However, for millennia fire was seen simply as a mystical force that could transform one substance into another burning wood, or boiling water while producing heat and light. Fire affected many aspects of early societies. These ranged from the simplest facets of everyday life, such as cooking and habitat heating and lighting, to more advanced uses, such as for making pottery and bricks and melting of metals to make tools.
It was fire that led to the discovery of glass and the purification of metals; this was followed by the rise of metallurgy. Certain metals can be recovered from their ores by simply heating the rocks in a fire: notably tinlead and at a higher temperature copper. This process is known as smelting.Some basic concepts of chemistry notes pdf, This book is mainly about Physical Chemistry and explains the basic concepts of gases, liquids and solids, class 11, class 12 chemistry, cbse board, ncert notes, physical chemistry notes, organic and inorganic notes which is very important to crack any competitive exam in India.
