Chemical bonds are what make up the world. In bonds‚ elements are held together and form compounds that may have new physical and chemical properties. There are two main kinds of bonds‚ they ionic and covalent. In bonding the goal of the atoms involved is to reach a level of stability with less energy. In order to reach the epitome of stability‚ as in the case of noble gases‚ an atom strives to complete its outer shell. Either losing or gaining electrons may do this‚ which concludes in an ionic bond

CHEMICAL WEATHERING Chemical weathering is a process of alteration of rocks of the Earth’s crust. is a chemical decomposition process. is brought out by atmospheric gases and moisture. End product has a different chemical composition and poorer physical constitution. The process: Chemical change in the nature of rock takes place in the presence of moisture containing many active gases such as CO2‚ N2‚ H2‚ and O2. Rocks are made up of minerals.

Chemical Reactions & Equations CHEMICAL REACTION : In a reaction when the original state of the particle changes and it cannot be reversed by simple physical means‚ this type of reaction is known as chemical reaction. Example :- Fermentation of grapes‚ burning of wood etc. In this reaction we have seen that after burning of wood‚ coal is formed and we cannot make wood from coal. PHYSICAL REACTION : In a reaction when original state of the particle can be recovered by any means then this type of
