  • Chemistry: The Elements And Structure Of Chemistry

    Everything is made of atoms, which are the smallest representative parts of each of the ninety-two elements that occur in nature. Elements are either metals, such as iron, copper or calcium or non-metals such as carbon, oxygen or nitrogen. Chemistry is concerned with the way atoms link together to form molecules, which are the natural chemical units of matter. Molecules represent the smallest particle of a chemical compound which retains the characteristics and chemical properties of the compound. With the rare exception of certain single atom molecules, almost all molecules consist of two or more atoms linked together. An atom of the violently active metal sodium (Na) linked to an atom of the poisonous gas chlorine (Cl), for instance, gives one molecule of common salt (NaCl) — an important body ingredient. Structure of the atom: There are two distinct regions to an atom. The first is a dense closely packed nucleus made up of protons and neutrons. Protons are positively charged and neutrons are neutral in charge. Together they make up much of the mass of the atom. They both have similar masses. Surrounding the nucleus are electrons. These are arranged in shells, or…

  • The Importance Of Chemistry And Chemical Changes In Chemistry

    Whether we notice it or not, chemistry lives in our bodies. Things such as skin conditions, digestion, breathing, and hair growth all deal with chemistry in their own way. They all have certain chemical reactions and chemical changes that affect the way our bodies work. Even though we study different curriculums during chemistry such as the chemical equations, chemical reactions, and other things we have learned go far beyond what is said in class. During food digestion there are…

  • The Importance Of Chemistry

    It was back and forth for a while. My guidance counselor would call me down to his office to discuss the idea that my high school was going to cut the AP chemistry class for the following year and I had to pick a new science class for my junior year. When I asked why he told me that there were only eleven people signed up for the class and that they wanted fifteen to keep it open. To be fair it was understandable that most people would not want to sign up. Many found honors chemistry to be…

  • Pharmaceuticals In Chemistry

    Pharmaceuticals are medicals drugs that are used or sold. When dealing with pharmaceuticals you have to deal with mixing substances together, knowing how much to put in every dosage, acids and bases, matter, chemical and physical properties, and etc. Pharmaceuticals are made of elements that are apart of the periodic table. That happens when combining two or more elements together causing a chemicals reaction. Also in chemistry is a law called the Law of Conservation of Matter which is used to…

  • Chemistry Reflection

    Chemistry is a branch of science that deals with the identification of the substances of which matter is composed. It also involves the properties and the ways in which they interact, combine, and change. Chemistry is important to life. The environment is composed of many chemicals without identification of chemicals we wouldn’t know what chemicals are safe to have around or which chemicals are harmful and dangerous to our bodies. To answer the enduring question, how do we gain knowledge to…

  • The Importance Of Writing In Chemistry

    Writing is not the first thing that comes to mind when the word chemistry comes appears. With the subject of chemistry, people usually think of cool experiments such as making toxic chemicals and blowing things up; however, writing plays a very vital part as a chemist. Dr. John Leyba, the chemistry and biochemistry department head and professor at the University of North Georgia (UNG), was able to give an insight of writing in the world of chemistry. Earning a Bachelor of Science in Truman State…

  • Questions On Chemistry

    Question 1: pH can be described as a measure of acidity or basicity (Alkalinity) of a solution. It is exactly equal in amount to the negative log of the concentration of hydronium(H3O+) ions. Due to the negative log relationship, increased hydronium ions transform to lower pH. When we add it to water, an acid releases hydrogen ion. Hydrogen ions in water unite with the water molecules to form hydronium ions, thereby lowering the pH and increasing the acidity of water. Water exposed to air is…

  • Spectroscopy In Organic Chemistry

    Types of Spectroscopy used in Organic Chemistry 1.1 Introduction Spectroscopy is the study of the interaction between matter and light (electromagnetic radiation) (Crouch & Skoog, 2007). It is often phrased as the light of knowledge (Reusch, 2013). In the past, spectroscopy started by the study of visible light dispersed according to its wavelength by a prism (Anon., n.d.). Now, with the knowledge of light having both wave-like and particle-like characteristics, with given frequency or…

  • Chemistry Lab Report

    Hey Mom, I know you’re dying to know how my semester is going so I thought I’d share with you some of the assignments I’ve been working on. I just finished my first chemistry lab project involving drugs! Yes, drugs, but not the ones you’re thinking about. We worked with Sulfanilamide, Phenacetin, Acetaminophen, and your favorite, Caffeine. The goal for the experiment was to determine where the drugs may reside according to their properties. We learned that there are parts in the cell that are…
