Chapter 6 - Answer Key to Section Review 1-3 Section Review 1 1. What is the main distinction between ionic and covalent bonding? Answer (A): Ionic bonding involves the electrical attraction between large numbers of anions and cations. Covalent bonding involves the sharing of electron pairs between two atoms. Translation: -Ionic bonding happens between a metal and a non-metal (east coast and west coast) -One atom completely donates its valence electrons to another atom -Metals

models of elements‚ compounds‚ and mixtures. The lab asks you to examine conceptual models of matter in which atoms of one element are represented by nuts while atoms of another element are represented by bolts. After examining each model‚ complete the following tasks: a. sketch a representative molecular picture of the model; b. describe the composition of the model in words (does the model contain atoms‚ molecules‚ or both?; does the model represent elements‚ compounds‚ or both?; does the

Chromatography Introduction/Background: Flavonoids are an important group of additives that can be defined as pure substances either natural‚ extracted from raw materials or synthetic. Chromatography is the separation of two or more compounds or ions caused by their molecular interactions with two phases – one moving and one stationary (Weldegirma 2012). Three types of chromatography are used in organic chemistry: Thin Layer Chromatography (TLC)‚ Gas Chromatography (GC)‚ and Column Chromatography

inside of a crucible‚ ultimately attaining a compound that contained Mg and O. The major result of the experiment was the empirical formula of the oxide of magnesium. III. Introduction An empirical formula is defined as a formula that gives the simplest ratio of the relative number of atoms in a compound. And as stated before‚ the goal for this lab was to ascertain the empirical formula for an oxide of magnesium. The formula was acquired by obtaining a compound that contained both magnesium and oxygen
