Title: Stoichiometry to Calculate Reaction of Zinc and Iodine and Law of Conservation of Mass Authors: Sang Nguyen and Sami Biro Introduction II. Materials and Methods A. Materials Zinc (Zn), iodine (I2), acetone (C3H6O), acetic acid (C2H4O2) and zinc iodide (ZnI2) were used to conduct this experiment in order to confirm the validity of the law of conservation of mass as well as to use Stoichiometry to calculate the reaction between zinc and iodine. There are some precautions that one must consider before handling and using these specific chemicals. All of the chemicals used impose at the minimal, hazard to skin and eyes. However, acetic acid in particular can be very hazardous with skin, eyes and inhalation and can potentially damage tissues according to the MSDS. B. Method 1 To set up the reaction between zinc and iodine (known as trial 1), 2.0 grams of zinc was first obtained and placed into a labeled test tube 1. After, 2.0 grams of iodine was used as well in the tube. Then, 5mL of dilute…

Zinc is an essential mineral that can be found in many foods or dietary supplements. The mineral zinc is found in the periodic table with the symbol ZN and has an atomic number of thirty. Zinc is one of the more abundant elements in the Earth’s crust, the twenty-fourth most abundant, and it contains five stable isotopes. This mineral is also known as an essential trace element, meaning the human body only requires a small amount to be considered healthy. One of the health benefits of zinc…

industries, the element zinc exists as a crucial factor within the world’s scientific realm. This bluish-white, lustrous metal was previously used in various industrial alloys and for medicinal purposes as early as 2,500 years ago by the Romans and Palestinians (“Zinc,” 2016). Greater rates of zinc production then began in India during the 13th century by heating mineral calamine with wool, yet no reference to it being its own discrete metal with its own scientific properties was made until…

Zinc and Immunity Various aspects of immune system are affected due to zinc (6,7,8). For normal development and function of cell mediated innate immunity, neutrophils and natural killer cells, zinc is essential element. The deficiency also affects the macrophages. The deficiency also affects adversely the growth and function of T and B cells. Besides zinc is an essential element needed for the synthesis of DNA, transcription of RNA, and activation of cells. Cytokines are adversely affected in…

Identities of Zinc, Sodium, Beryllium, Copper and Boron By: Shreya Uppala, Lizzy Jolly, and Kyrie Harrell Results: The first element we tested was zinc. Since zinc was already known, the density was stated to be 7.13g/mL and the hardness was a 2.5 based on the Mohs Hardness Scale. No magnetic attraction was observed when in contact with a magnet. Zinc had a shiny appearance with a light gray color and the strips of zinc added to solution were approximately 5 cm. When zinc was tested with water…

Corrosion is when metals or other materials corrode over time. “Corrosion is a two-step process that requires three things: a metallic surface, an electrolyte, and oxygen. During the corrosion process, surface-level metal atoms dissolve into an aqueous solution, leaving the metal with an excess of negative charge.”(Corrosion, Boundless Chemistry, First two bullet points) The nail will undergo a corrosion process as it is placed in the cup filled with salt water. However, depending on the coating…

Discovered as a deficiency in the early 60’s, the chemical element zinc serves multiple roles in the body. Zinc travels through the body by protein which assists other proteins with metabolism. Moreover, zinc play a role in growth, development, behavior, and learning. In addition, zinc aids hormones such as thyroid and insulin. Zinc deficiency remain common in developing countries while less common in the United States…

in the concentration of metal ions of the cathode in a Zinc-Copper electrochemical cell affect the electrical potential? Introduction: In a highly technological and quickly developing society, it is imperative to innovation that basic components are understood and explored to further expansion and advancement. In order to understand how everyday necessities such as cars, computers, and cell phones are constantly powered, it must first be understood what is in a battery as well as what happens…

Abstract: This paper provides a brief summary of existing article Zinc Oxide Nanoparticles with Defects by Vladislav Ischenko,Sebastian Polarz,Dirk Grote,Victorina Sravarache,Karin Fink,and Matthias Driess. This paper discusses the importance of a nanoscale ZnO with defects in its structure. The article also provides a broad analysis of ZnO nanoparticles using a consolidation of techniques and the resulting data is summarised in this review. The paper gives the realization of when a…

Zinc is the member of the first row transition series of elements, consisting of Sc, Ti, Cr, Mn, Co, Ni, Cu, Zn, Cd and Hg. All these elements belong to group 12 of periodic table. Zinc has an atomic number 30, an atomic mass of 65 and one main oxidation state (+2). Zinc has five nature isotopes . Zinc is the 24th most abundant element in the earth’s crust. Its properties is very similar to Cd.Zinc is very useful in biological systems. Zinc also is involved in many biochemical processes that…
