• Whenever a chemical change occurs, we can say that a chemical reaction takes place i.e Chemical reactions involve chemical changes. Chemical Change :   • If the identity, composition or nature of a chemical substance change and can not be reserved by any physical process, it is called chemical change . Chemical Reaction :   • The process involving a chemical change is called chemical reaction . • The process in which one or more substance as reactants gets converted (transformed) into new substances with new properties in product as a result of chemical change is called chemical reaction . Reactants :   • The substances that undergo chemical change or takes part in a chemical reaction is called reactants .  Products :   • The new substances produced (formed) during the reaction as a result of chemical change are called products . • Chemical reactions involves the breaking and making of bonds between atoms i.e in a chemical reaction old bonds are broken to form a new bond

 Fact no' 1. Why do old book smell so good? Chemistry behind this.👇👇👇👇👇👇🥀 Smell of old book is due to the paper and ink in those Books. As we all know that paper is made up of wood and wood is made up of organic compounds like cellulose and lignin. Over the years these compounds reacts in the presence of light, heat and air and begin break down releasing VOC. VOC means volatile organic compound. These compounds easily vaporized and mixed in air, and thus forming smell of old book. Organic compound called vanillin gives vanilla like smell. Benzaldehyde give almond like smell. Ethyl benzene gives a sweet smell. This compound are mixed and gives good smell of old book's. Fact no' 2. Fact About Matter. As we know that, there is some empty sapce in matter i.e in Solid, Liquid and gas. If we remove the empty space from the matter, the whole word can be fit in the same size of an Apple. Fact no' 3 Chemical compound resemble with penguin. Penguinone is an organic compou

The Human Eye : • The human eye is one of the most valuable/significant sensitive light sensing organ which helps/enable us to see the beautiful / wonderful colorful world & object around us. • It is the natural optical Instrument. • It has lens (convex) in its structure. • It works on the refraction of light. • It is spherical in Shape like a ball of diameter about 2.3 cm. The main/essential parts The human are: 1. Cornea: • Light enters the eye through a thin, transparent membrane is called cornea.  • It is front projected part of eye bulging outwards. • Light first enters our eye through this.  • It refracts most of the incident light into the eye. • It protect eye from foreign agents like dust. 2. Aqueous humour: • Between the cornea & eye lens, their is a space filled with transparent Liquid (water like consistency) called Aqueous humour.  • It helps the refracted light to be focused on retina • It also provides nutrition to eye as well
