Experiment 3: Chemical Equilibrium Purpose The purpose of this experiment was to determine the equilibrium constant for the formation of FeSCN2+. Introduction Chemical equilibrium is the point in a reversible reaction where the concentration of the reactants and that of the products remains constant. This point of equilibrium is referred to as the Kc value‚ which can be obtained using the formula: Kc = [product] [reactant] In this experiment‚ we used a spectrophometer to

Larger amount of energy is needed to overcome the stronger electrostatic attraction between Al3+ and F( ions in AlF3 than the weaker intermolecular forces (or van der Waals’ forces/ permanent dipole –permanent dipole attraction) between PF3

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

PERMANENT SOVEREIGNTY OVER NATURAL RESOURCES The general assembly adopted the resolution 1803 (XVII) on the permanent sovereignty over natural resource‚ on the 14 of December 1962 by 87 votes in favour to 2 against‚ with 12 abstentions. The general assembly also established the united commission on permanent sovereignty over natural resources on 12 December 1958 under resolution 1314 (XIII). In 1961‚ this commission adopted a draft resolution outlining principles concerning permanent sovereignty

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

Drugs and Chemicals to be Avoided in G6PD Deficiency Drugs to be Avoided in G6PD Deficiency There are different types of G6PD deficiency‚ an individual need to know the type of G6PD that they have inherited because each types of G6PD deficiency react to drugs differently and some may not react to some of the drugs and chemicals listed here. This is not a comprehensive list there are drugs and chemicals that may also be harmful to those with G6PD deficiency that are not on this list an individual

The purpose of this experiment was used to identify the chemical changes a substance undergoes by knowing some of its chemical properties like (Change in color‚ producing bubbles and gas‚ precipitation‚ conductivity). The aim of today’s lab was to help us identify different households and their components‚ they contained whether they were acid/ base‚ because most of the households are based on those solutions like (i.e. Acetic acid = Vinegar = CH3COOH can be used in cooking) or bases solutions

Purpose: To Inform Topic: Chemical Warfare Intro 1) Chemical weapons are extremely toxic chemicals which differ from explosive weaponry. Middle ages and renaissance are documented to have used poisonous chemicals on individuals. Chemical warfare is use of chemical agents to kill or incapacitate the enemy. 2) Today I will inform you of different chemical agents. Since World War I‚ several types of agents have been developed into weapons. These chemical weapons include (I) Choking

When I started the single-factor productivity analysis it looked as if productivity were headed in the right direction ’’ up. Because the outcomes of both the units per RMU and units per labor hours had an increase‚ 3.59% and 4.79% respectively. Even with the increase in cost per barrel from
