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 Chemistry in Chili For my 2018 Chef Speciality project I will be explaining the chemistry included while cooking chili. Chili is a commonly cooked and served dish and is widely enjoyed across the whole nation. The chili recipe that I will be using includes 2lbs of extra lean ground turkey‚ ½ cup of chopped onions‚ 1 tbsp. Garlic powder‚ 3 oz of diced green chilies‚ 10 oz of can tri- bean blend (drained)‚ 10 oz can organic black beans (Drained) 10 oz of organic diced tomato‚ 1 tbsp. Xylitol

When you smell food your stomach rumbles with hunger. Food is everywhere. It’s all around us‚ it’s our main resource to live. You can buy food from anywhere you want‚ but what about the World War Two soldiers‚ why couldn’t they get whatever they wanted. World War Two soldiers had limited protein on their canned food back then‚ in this day and age you can get protein from anywhere. Food is a very scarce resource and it was relied a lot by the soldiers‚ in which they got small portions of it.
