Chemical kinetics‚ also known as reaction kinetics‚ is the study of rates of chemical processes. Chemical kinetics includes investigations of how different experimental conditions can influence the speed of a chemical reaction and yield information about the reaction’s mechanism and transition states‚ as well as the construction of mathematical models that can describe the characteristics of a chemical reaction. In 1864‚ Peter Waage and Cato Guldberg pioneered the development of chemical kinetics

Economy of Vietnam By Adam McCarty Introduction Vietnam has been a country ruled by colonists‚ divided or at war for most of the twentieth century. Unification of the country in 1976 was followed by invasion of Cambodia in 1978‚ and a subsequent brief but violent war with China. This troubled history had profound consequences for economic development in general‚ and attempts to impose central planning in particular. Central planning was imposed upon Northern Vietnam in the 1950s‚ and upon

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. All the minerals in a rock are not in

Chemicals of Life • With the exception of water‚ virtually all chemicals of life are CARBON based • Molecules that contain Carbon are considered organic with some exceptions such as CO2 • Carbon has 4 valence electrons so it is oriented in a tetrahedron shape Sketch→ • Carbon can form up to 4 covalent bonds and can form long chains‚ rings‚ and branched chain molecules • Carbon acts as the backbone of biological molecules • Molecules that only contain carbon and hydrogen are known as hydrocarbons→
