Procedure Read through the following Procedures and then draw a data table in your notebook to record your observations about any precipitates or gases that form when the two solutions are combined. Remember to include color for precipitates. Examine the reactions against both dark and white backgrounds. If there is no reaction for that combination of solutions write NR (no reaction). Before beginning‚ set up a data table similar to the Data Table: Solubility Rules Table in the Lab Report

03.04 Valence Electrons and Bonding Individual neutral atoms are rarely found in nature. The noble gases are the only elements that are found as single atoms more often than they are found in compounds. Atoms are held together in compounds by electrostatic attraction between positive nuclei and negative electrons. This attraction holds atoms together in a chemical bond‚ a link between two atoms resulting from the mutual attraction of their nuclei for valence electrons. All chemical bonds involve

everyday lives. Many artists today even try to mimic artists in ancient Greece‚ but often fail to do so. One of the most important aspects to come out of Greek art is the architecture‚ most notable the three architectural orders of ancient Greece‚ Doric‚ Ionic and Corinthian. Each components of this order has a system of inter dependable parts whose proportions are based upon mathematical ratios. The basic components of all three orders are the column and entablature. Although most people do not know this

The bonding of an enzyme to its substrate forms an enzyme-substrate complex. The catalytic action of the enzyme converts its substrate into the product or products of the reaction. Each reaction is extremely specific‚ distinguishing between closely related compounds‚ including isomers. For example‚ the enzyme sucrase will only act on sucrose and will not bind to any other disaccharide. The molecular recognition of enzymes is due to the fact that they are proteins‚ which are defined as being macromolecules

Purpose: The purpose of the lab was to observe what happens when two ionic compounds are combined in a small area and to be able to record the type of precipitate that is formed. Background: An ionic compound is formed when ions “transfer‚” or lose or gain electrons. The ions in an ionic compound are held together by ionic bonds in a lattice shaped structured. They are packed tightly together to maximize the attraction between the ions. When two compounds are mixed together‚ they form a precipitate

The purpose of this experiment is to work with aqueous solutions of ionic substances. Aqueous solutions are those solutions in which water is the solvent. When ionic substances are dissolved in water‚ the ions separate and become surrounded by water molecules. The focus of this experiment is on precipitates. The goal of this experiment is to study the nature of ionic reactions‚ write balanced equations‚ and to write net ionic equations for precipitation reactions. Based on the solubility rules my

Subject: Chemistry Topic: The Periodic Table The periodic table is a classification of all the elements based on ATOMIC NUMBER. It is composed of HORIZONTAL PERIODS and VERTICAL GROUPS which contain the elements arranged: *the order of INCREASING ATOMIC NUMBER *in the relation to the ELECTRON STRUCTURE of the atoms *in the relation to their CHEMICAL PROPERTIES (Criteria Used For Placing ELEMENTS in the Periodic Table) 1. ATOMIC NUMBER 2. NUMBER OF SHELLS (PERIOD) 3. NUMBER OF OUTER

Goals The main goal of this project is to learn how to identify the properties of an unknown ionic compound. In order to do this successfully the group has to use a variety of methods and run several tests on the unknown compound. By doing this the group will be able to identify the different chemical and physical properties of the compound that will help obtain the identity of the specific compound given. The group will devise two syntheses of the compound‚ and compare them for cost effectiveness

Discuss the Role of Hydrogen Bonding in living Organisms A hydrogen bond is an intermolecular bond and is formed when a charged part of a molecule having polar covalent bonds‚ forms an electrostatic attraction with a molecule of opposite charge‚ generally with fluorine‚ oxygen and nitrogen. Molecules having non polar covalent bonds do not form hydrogen bonds. Hydrogen bonds are classified as weak bonds as they are easily and rapidly formed and broken‚ however the cumulative effects of large
