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

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

HOW TO APPLY A CHEMICAL RELAXER Being a professional hair stylist people are always asking me what is the proper way to apply a relaxer. There is no time to teach a class‚ so follow these simple instructions to get the best results. First‚ part the hair into four or five sections‚ depending on the thickness of the hair. Dry the hair. If moisture or sweat is present on the scalp get under a cool hair dryer for several minutes. It is recommended to apply protective cream around the hair line

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→

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

Chemical Equilibrium: Le Chatelier Principle By Sarah Ramos and Kristina Todorovic Chemistry 203 DEN Dr. Mohamed El-Maazawi Part A. Acid-Base Indicators Purpose In this part of the experiment‚ we will find a reagent that will shift the acid-base equilibrium reaction described by Equation (2) in one direction and then a second reagent that will cause the equilibrium position to shift back in the opposite direction. Introduction An acid–base indicator
