Strontium Isotope ratios are used in archaeology to track human migration.86Sr abundance is constant, but 87Sr forms through decay of 87Rb in rock. Rock age and initial Rb/Sr ratios vary geographically, making87Sr/86Sr a location tracer. Strontium, weathered from bedrock into groundwater then taken up by flora and fauna, can substitute for Ca in tooth enamel. Enamel only forms during childhood, specifically the early first and second molars mineralize during early childhood; the third molar…
The testable question asked what is the actual percent yield of copper produced in grams/milliliters from the reaction of 2 g of solid copper (II) sulfate pentahydrate and approximately .25 g of aluminum foil in 10 mL of water versus the theoretical yield of copper metal. The hypothesis stated that if a reaction occurs between 2 g of solid copper (II) sulfate pentahydrate and 2 mL of 6 molar hydrochloric acid with approximately .25 g of aluminum foil, then the actual percentage yield of copper…
My chemical element is Sulfur. If you were to be looking at a periodic table, its symbol would be S. Sulfur’s atomic number is 16. Sulfur has 16 protons, 16 electrons, and 16 neutrons. Sulfur’s atomic mass is 32.065 and its mass number is 32. Sulfur comes from the Sanskrit word “Sulvere” and also the latin word “Sulphurium”. Sulfur was discovered in Ancient times and has been mentioned in both the Bible and the Torah. Sulfur is commonly found in meteorites, volcanoes, hot springs, and as…
Akasha: The Fifth Element Akasha, or Spirit, is simply the fifth element. While most everyone is familiar with Earth, Air, Fire and Water, Akasha is what binds these elements together. Akasha would be the same as white light – the combination of all colors, indicating that Akasha is all Elements in one. When I think of Akasha, I think of Spirit. When I explain to others with Christian faith on my perspective of God, I explain to them that I have a personal relationship with “God” which is my…
Lots of American farmers found themselves unable to make enough money to support their families. One of the main ingredients of Moonshine is corn. A farmer could take a subpar corn farm and turn it into a goldmine. Obviously the Government did not approve of this practice. There are a couple good reasons for the Government to oppose this practice. With underground Moonshine sales growing they were losing a large amount of tax revenue; secondly, there was no way to regulate production, and…
Magazine, Mental Floss, Slate, The Believer, Air & Space, Science, and The New Scientist, has created a user-friendly book about how to explain the periodic table and the elements that occupy it by writing the book The Disappearing Spoon: And Other True Tales of Madness, Love and the History of the World From the Periodic Table of Elements. He provides an insight into the world of chemistry that relates to his audience, even those who do not have a PhD in a science field. As the book goes on,…
society are weak. These element of the bond to society are attachment, belief, commitment, and involvement. My main focus will be on the attachment element of the bond. Attachment is the concern individual have about what people think of the individual. Belief is the traditional value system that many individuals belief in. Commitment is related to the individual aspiration to achieving their goals. Involvement is the activities the individual is involved in. If these elements are strong, then…
Atoms are what make up what we call “matter.” They are the smallest units of a chemical element, and they consist of protons, neutrons, and electrons. These components form an atom’s subatomic particles. Before discussing the copper atom at length, we must first be able to understand the components that comprise an atom. The first of these components that make up an atom is the proton. The proton is a very important part of an atom, because the atomic number of an atom is equivalent to the…
The Composition of Copper Copper is an element that many people have either felt or seen without realizing it. Pennies, for example, are made of copper. Certain pipes, contraceptives, and wires are other ways copper is used in our daily lives. It 's a great conductor of electricity, antibacterial, and corrosion resistant. However, this raises the question: what exactly are the properties of copper that give it its properties? An element is a chemical substance in its simplest form. An atom is…
Empirical formulas are the simplest whole number ratio of the elements present in a compound (Owen, 2014). However, the actual amount of each type of atom that a compound is consisted of is called the molecular formula. For that reason, the deduction of the empirical formula and the molar mass of a compound is required to determine the molecular formula of the compound. To determine the empirical formula experimentally, the mass of each element has to be obtained, and converted into its…
