So how chemicals and chemical reactions are important for life.
00:07
So chemical reactions are very important for life because the whole world around us is comprised of many chemicals.
00:17
So the word around us, the word around us comprised of a millions of chemical, comprised of a million of chemicals, million of chemicals, which reacts with each other and undergo changes, which react with each other and undergo changes.
01:08
Some changes may be useful, some changes may be useful while others can be harmful for life, others can be, harmful for life so the best way to observe analyze and interpret the best way to analyze to observe analyze and interpret from these changes these changes is by representing these reaction is by representing these reactions representing these reactions with the help of chemical equations with the help of chemical equations chemical equations so chemical equations are the symbols representation of the reaction so chemical equations are the symbols representation of the reaction so chemical equations are the symbols the symbols representation of the reaction are the symbols representation of the reaction that can take place.
03:30
So they include the entities, they include the entities that react, that can react, the entities that are produced, the entities that are produced, the physical state in which the physical state like solid liquid or gas, the physical state in which these entities are present.

These entities are present...
