    Net Ionic Equations

    09. Net Ionic Equations tutorial.doc Introduction to Net Ionic Equations This tutorial will give you an algorithm for writing net ionic equations for aqueous reactions in general chemistry. Knowledge of the solubility rules is necessary to complete this tutorial. A list of solubility rules is provided at the end of the tutorial for review. Net ionic equations are necessary in chemistry for several reasons: 1. They show only those species undergoing chemical change – “spectator” ions are removed

    Bryan Ralloma Jennifer Caraway CHEM 1405-034 April 9, 2014 Balancing and Classifying Synthesized Chemical Reactions Abstract During the experimentation, physical and chemical properties of unaltered elements/compounds were noted. The alteration of these physical and chemical properties, were understood to have defined chemical change. The experimental procedures were divided into five phases: Magnesium and Oxygen, Zinc and Copper(II) Sulfate, Metals and HCl, Reactions of Ionic Compounds, and

    Oxidation

    Oxidation-reduction reactions (or redox) reactions, are a type of reaction in aqueous solutions that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an e-. They occur every day and are vital to some of the basic functions of life. Some examples include photosynthesis (within plants), respiration (within animals), combustion, and corrosion or rusting

    | | | 1. Part 2: Single-Displacement Reactions: For each four single-displacement reaction, describe what happened in each well. If a chemical reaction occurred, write a balanced equation for it. Then use the A, B symbols to write a general equation for a single-displacement reaction. Here are the chemical formulas of the reactants for each reaction: • zinc – Zn copper sulfate – CuSO4 • aluminum – Al copper sulfate – CuSO4 • zinc – Zn

    The Stochiometryu

    Stoichiometry is simply the math behind chemistry. Given enough information, one can use stoichiometry to calculate masses, moles, and percents within a chemical equation. ________________________________________ ________________________________________ What is a Chemical Equation? In chemistry, we use symbols to represent the various chemicals. Success in chemistry depends upon developing a strong familiarity with these basic symbols. For example, the symbol "C"represents an atom of carbon, and
