Zinc and magnesium metal each react with hydrochloric acid according to the following equations: A 10.00-g mixture of zinc and magnesium is reacted with the stoichiometric amount of hydrochloric acid. The reaction mixture is then reacted with 156 mL of 3.00 M silver nitrate to produce the maximum possible amount of silver chloride. a. Determine the percent magnesium by mass in the original mixture. b. If 78.0 mL of HCl was added, what was the concentration of the HCl?
Chapter 4 VII. drawing Lewis dot structures for polyatomic ion A. the charge of the ion should be taken into account when placing the valence electrons B. Sulfate will have two extra valence electrons because it has a -2 charge VIII. resonance- when two or more electron dot structures can be written with multiple bonds A. hybrid= mix of two structures IX. properties of ionic bonds: solid at room temperature, high melting and billing point, good conductors, no prefixes, are metals and non-metals, transfer electrons Properties of covalent bonds: solids, gases or liquids at room temperature, low melting and boiling point, non-conductors, uses prefixes, 2 non-metals, shared electrons
