Organic vs. Inorganic Le’Trice Crawford CRJ311: Forensics Christopher Mancuso May 18 ‚ 2012 The world that we live in is made up of organic and inorganic materials. The thing is known which is when you are confronted with a list of objects. This is the reason in this paper I intend to show the difference between organic and inorganic organisms. The definition of organic which means‚ of or pertaining to an organ; or the organs of an animal

Scope and Delimitation Base on our knowledge‚ the magnesium and potassium that are on the table of elements‚ gives vitamins on our tooth. We think that if potassium and magnesium gives vitamins on our tooth‚ it is possible that it can whiten our tooth D. Significance of the study The Benefits of the banana peel to whiten our teeth is to make some people

named the unknown mineral strontianite (SrCO3). Later in 1798 it was separated into its pure form by Scottish physician and chemist‚ Thomas Chares Hope. Strontium was first isolated by English Chemist Sir Humphry Davy in 1808. How and where is the element found?- Strontium commonly occurs in nature and forms up to 0.034 of igneous rocks and is also found I the form of the Sulphate mineral Celestine (SrSO4) and Carbonate Strontianite (SrCO3). The main mining areas for Strontium is in areas of UK‚

relationships between wavelength and atomic number. Among his achievements he also predicted missing elements from the periodic table. Many people believe had he lived a little longer he would have surely received the Nobel Prize. His work also helped with placing difficult elements such as argon and potassium. Henry Moseley inspires me because he developed a new method of organizing the elements. Further inspiration he inspires is to always do the best you can because he may have come from a rich

the gas produced in his experiments ’dephlogisticated air’ and Scheele called his ’fire air’. The name oxygen was created by Antoine Lavoisier who incorrectly believed that oxygen was necessary to form all acids. Oxygen is the third most abundant element in the universe and makes up nearly 21% of the earth’s atmosphere. Oxygen accounts for nearly half of the mass of the earth’s crust‚ two thirds of the mass of the human body and nine tenths of the mass of water. Large amounts of oxygen can be extracted

EUCLID: The Man Who Created a Math Class Euclid of Alexandria was born in about 325 BC. He is the most prominent mathematician of antiquity best known for his dissertation on mathematics. He was able to create "The Elements" which included the composition of many other famous mathematicians together. He began exploring math because he felt that he needed to compile certain things and fix certain postulates and theorems. His book included‚ many of Eudoxus’ theorems‚ he perfected many of Theaetetus’s

The current periodic table lists 109 elements. It is arranged according to the periodic law; elements are arranged in order of increasing atomic number‚ their physical and chemical properties show a periodic pattern. Elements that have similar properties are arranged in groups or families in vertical columns‚ the horizontal

on the atomic number and type of material‚ and how this specific area determines its atomic “identity” and relation to other elements. This also includes the reactivity of elements based on their electron configurations. This relates directly to what we have studied in Chapter 5 of our textbook. One example from The Disappearing Spoon was about the halogens group of elements. This group is one of the most reactive of the entire periodic table because the outer shell of electrons in each atom is missing
