this experiment was to obtain some experimental measurement of Vapor Liquid Equilibrium for the Ethanol – Water system to verify the literature data. For this the Ethanol – Water system was heated to a certain temperature which is called the equilibrium temperature at atmospheric pressure and equilibrium temperature and compositions of vapor and liquid were measured. At the equilibrium temperature the samples of both vapor and liquid were taken in two different test-tube and the refractive index of

Making homemade liquid soap is not as challenging as you may think. With just a few ingredients and a little bit of time‚ you can make your own liquid soap right in the comfort of your home. If you are looking to save some money‚ or just want a fun project to do at home‚ you can create a homemade product that works just as well as commercial-grade soaps at a fraction of the cost. You will need to spend some money upfront‚ but you can make several batches of soap with the ingredients. Bar soap works

CHEMICAL BONDS Chemical Bonds I. Introduction Chemical compounds are formed by the joining of two or more atoms. A stable compound occurs when the total energy of the combination has lower energy than the separated atoms. The bound state implies a net attractive force between the atoms called a chemical bond. The two extreme cases of chemical bonds are the covalent bonds and ionic bonds. Covalent bonds are bonds in which one or more pairs of electrons are shared by two atoms. Covalent bonds

Analysis of a Volatile Liquid Abstract: The purpose of this experiment was to use various methods of analysis to determine the identity of an unknown volatile liquid. In the first part of the experiment‚ the molecular mass was found by using water to find the volume of a flask through calculations and this as well as the mass of the gas of the unknown liquid were put into the a manipulated version of the ideal gas equation to determine the molar mass of the liquid‚ which was 14.21g per

Case 3: The Grayson Chemical Company The Company The Grayson Chemical Co. manufactured industrial chemicals for sale to other industrial companies. The company was about 40 years old and had been run by a stable management under only two presidents. Within the past few years‚ however‚ declining earnings and sales had brought pressure from the board of directors‚ investment bankers‚ and stockholder groups to name a new president. The company had grown increasingly stagnant – although at Grayson

light‚ which is evidence of a chemical change. The second reaction occurred as a result of solid magnesium reacting with hydrochloric acid. The reaction produced heat and bubbles‚ both indications of a chemical change. A wood splint was used to determine that the gas produced was hydrogen gas‚ hence the other product is magnesium dichloride. In the third reaction‚ ammonium carbonate was heated to decompose into two gases‚ due to the absence of anything solid or liquid following the reaction. A wood

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
