Chemical Periodicity Gorospe‚ Jheremy Alden B. ____________________________________________________________________________________ ABSTRACT The experiment Chemical Periodicity was demonstrated by using different samples of Group IA‚ Group IIA and Group IVA elements. We placed each of the samples in each test tubes and the physical state‚ color‚ and appearance was identified. We determined the solubility of the elements by using distilled water. We used red and blue litmus paper for the Group

heterogeneous methanol process for the production of acetic acid. This technology is based on a heterogeneous Rh catalyst in which the active Rh complex is chemically immobilized on a polyvinylpyridine resin. In the Aspen Plus model‚ the plant (base case) is designed to produce 800 million lb/yr (363‚000 t/yr) of acetic acid from methanol carbonylation. The process consists of both the carbonylation and purification sections. Results from the Aspen Plus simulation shows that the purity of acetic

Chemical Nomenclature refers to the naming systems used with chemical formulas. This worksheet focuses on the most basic chemicals and nomenclature systems. Please read the information concerning each problem set and then attempt the problems associated with that information. The simplest compounds contain just two elements. Sodium chloride‚ NaCl‚ is an example of a binary compound. Several other examples are listed below. Potassium bromide KBr Calcium bromide CaBr2 Lithium fluoride LiF

In the first reaction‚ magnesium was burned to produce magnesium oxide. The reaction produced a bright light‚ which is evidence of a chemical change. The second reaction occurred as a result of solid magnesium reacting with hydrochloric acid. The reaction produced heat and bubbles‚ both indications of a chemical change. A wood splint was used to determine that the gas produced was hydrogen gas‚ hence the other product is magnesium dichloride. In the third reaction‚ ammonium carbonate was heated to

Element: Simplest form of matter to have unique chemical properties. Atom: The smallest particles with unique chemical identities. Nucleus: Center of an atom (composed of protons and neutrons). Proton: Have a single positive charge (+1). Neutron: Have no charge. Electron: Tiny particles with a single negative charge and very low mass (-1)/determines chemical bonding properties of an atom. Atomic Number: Number of protons in the nucleus. Atomic Mass: Approximate number of protons and neutrons

Chemical reactions involve the making and breaking of bonds. It is essential that we know what bonds are before we can understand any chemical reaction. To understand bonds‚ we will first describe several of their properties. The bond strength tells us how hard it is to break a bond. Bond lengths give us valuable structural information about the positions of the atomic nuclei. Bond dipoles inform us about the electron distribution around the two bonded atoms. From bond dipoles we may derive electronegativity

INTRODUCTION TO CHEMICAL BONDS CHEMICAL BOND Definition: A chemical bond is defined as a force that acts between two or more atoms to hold them together as a stable molecule. Main types of bond: 1. Ionic or electrovalent bond‚ 2. Covalent bond‚ 3. Coordinate covalent bond Forth type of bond: Metallic bond: The type of bonding which holds the atoms together in metal crystal. Valence electron: The electrons in the outer most energy level in an atom that takes part in chemical bonding
