This is important for the students to appreciate the knowledge of chemistry that is still new for themselves. Personally‚ I think that this chapter is an interesting chapter as it revealed the way of scientist produces the material around me. It also gives me new knowledge of the uses of chemical substances that I usually found in the laboratories. I hope‚ by learning this chapter‚ I will be more interested in learning chemistry as it will help me in the future. All the equations from this chapter

It is a low fat high fiber diet that will help you lose those few extra pounds. People who intend to enroll in other long-term diet programs also use the cabbage soup diet to help them get into shape or lose some of those fats before signing up. The cabbage soup and water are the central figures in the diet program. Based on this fat-burning

atoms can rotate and vibrate with respect to each other. These vibrations and rotations also have discrete energy levels‚ which can be considered as being packed on top of each electronic level. UV/Vis spectroscopy is routinely used in analytical chemistry for thequantitative determination of different analytes‚ such as transition metal ions‚ highly conjugated organic compounds‚ and biological macromolecules. Spectroscopic analysis is commonly carried out in solutions but solids and gases may also

Gas Chromatography (GC) Definition: Gas chromatography is a physical method of separation in which the components to be separated are distributed between two phases‚ one being a stationary bed of large surface area‚ and the other a gas that percolates through the stationary bed. When the stationary phase is a solid‚ the separation process is more precisely called gas-solid chromatography. Introduction: Gas Chromatography is a technique widely used to separate complex mixtures of substances. Compounds

In the 18th and 19th centuries scientists wrestled with identifying and describing the nature of the “stuff” that produced change. One concept that became popular for a while was that of “caloric” (what we now call heat). “Caloric was originally conceived of as a quantity that would flow from a hotter object to a cooler one that would warm up as a result. It answered the need for a way for the cause of warming to get from here to there. Not only did caloric serve as a cause for warming‚ it

The identification of acids and bases using a natural indicator Purpose: The purpose of this lab practice is to identify the pH of certain solutions and if they are acids or bases. Introduction: In chemistry‚ pH is a measure of the activity of the (solvated) hydrogen ion. p[H]‚ which measures the hydrogen ion concentration‚ is closely related to‚ and is often written as‚ pH. Depending on the pH solutions will be acids or bases. An acid is a chemical compound that dissociates in solution‚ releasing

Chemistry Ozone Depletion Ozone depletion describes two distinct but related phenomena observed since the late 1970s: a steady decline of about 4% per decade in the total volume of ozone in Earth’s stratosphere (the ozone layer)‚ and a much larger springtime decrease in stratospheric ozone over Earth’s polar regions. The latter phenomenon is referred to as theozone hole. In addition to these well-known stratospheric phenomena‚ there are also springtime polartropospheric ozone depletion events. The
