Flame Tests Atomic Emission and Electron Energy Levels AES‚ or atomic emission spectroscopy‚ is a method which chemically analyzes the particular wavelength of a sample element to identify and determine the abundance of this certain element. The wavelength of the atomic spectral line unveils the identity of the element while the emitted light intensity is proportional to the number of atoms in the element. The flame test is also a very effective way to identify an individual element. The color

AN APPLE A DAY There used to be a huge old apple tree near my granny’s house though at the time I was just a shy little girl and all the trees in our garden were enormous giants for me. Every autumn the tree bore not very big and a bit sour apples but my granny managed to cook delicious pies with them. “Treat yourself to one more piece of pie‚ honey‚” used to tell me granny. “You know an apple a day keeps the doctor away.” “So it’s because of the apples that we haven’t got one in our village‚

This lab was conducted to physically see the breakdown of carbohydrates into simpler sugars (glucose‚ fructose‚ galactose) using the salivary amylase enzyme. This is extremely important to all metabolic functions in the human digestive system. It

INTRODUCTION Flame photometry‚ also referred to as ’flame atomic emission spectrometry ’ is a quick‚ economical and simple way of detecting traces of metal ions‚ primarily Sodium‚ Potassium‚ Lithium‚ Calcium‚ and Barium‚ in a concentrated solution. The process is an extension of the principles used in a flame test‚ with the main differences having more precision in the results‚ and the use of more advanced technology. This report focuses on the theory‚ applications‚ limitations and analysis of Flame Photometry

The novels Every Day is for the Thief by Teju Cole‚ Americanah by Chimamanda Ngozi Adiche‚ and Ghana Must Go by Taiye Selasi all exemplify the tumultuous nature of choosing to return to Africa or not. This idea is further expounded upon by its relationship with privilege as an influence on the decision. The problematic essence of this decision lies within the relationship it has to privilege. In all three novels‚ the protagonists only ever want to return home once they have been successful abroad

Introduction For the last week‚ specific tests had to be applied to determine the unknown solid that was given out randomly. Physical tests‚ solubility test‚ characteristic tests‚ NMR spectrums‚ and IR spectrums were all utilized to distinguish the identity of the solid. These assessments and a couple additional tests will be utilized again to determine the unknown liquid that was given to us in class. The other characteristics that will be looked at will be the boiling point‚ refracted index‚ and

How is geometry used in everyday life? When you’re studying a subject‚ the science of lines and angles can seem like nothing more than a dull exercise in formulas and predictability. In reality‚ geometry is at work everywhere you go. Whether you’re aware of it or not‚ geometry quite literally shapes our lives. An Ancient Science‚ how long has geometry been around? To answer that question‚ let’s take a look at where geometry gets its name. Geometry is derived from the Greek words for Earth (Geo)

Each element emits a unique color light. The purpose of this experiment was to observe these unique colors and calculate their energy. In order to observe this‚ we placed the physical elements in a 24 well plate‚ dipped wet q-tips into the wells to gather the element‚ and put it over the bunsen burner to observe the flame emitted. While observing the different flames‚ we saw that different elements did indeed emit unique flame colors. Colors such as red‚ violet‚ and turquoise were emitted. All of
