Reactions in Aqueous Solutions: Metathesis Reactions and Net Ionic Equations Introduction: Metathesis or double decomposition reactions are a reaction in which two compounds react to form two new compounds‚ with no changes in oxidation number. The ions of two compounds exchange partners. AX + BY AY + BX This reaction can occur between two inorganic salts when one product is insoluble in water‚ driving the reaction forward. A typical example is as followed and is considered a molecular equation

Redox reactions (Redox terminology‚ galvanic cells‚ standard electrode potentials‚ strength of oxidizing/reducing agents‚ corrosion and protection against it) Oxidation is defined as the loss of electrons and reduction is defined as the gain of electrons. Oxidizing agents‚ such as oxygen are defined as substances which accept electrons; reducing agents are substances which donate electrons. Redox reactions are: a) The reactions of metals with non-metals 2Na+Cl2→2Na+Cl- b) The reactions

THE PREAMBLE AND THE BILL OF RIGHTS By 1787‚ Americans were dissatisfied with the current form of the United States government. The Articles of Confederation‚ although adequate when created‚ had some major draw backs. An elite group‚ known as the framers‚ assembled to form a more perfect union.

The most renowned committee

REACTIONS OF HYDROCARBONS Vanessa P. Manibpel De La Salle University - Dasmariñas ABSTRACT Five substances namely Hexane‚ Eugenol‚ Unknown hydrocarbon 1‚ Unknown hydrocarbon 2‚ and Acetylene gas was used for the selective reactivity of hydrocarbons to functional group tests; Bayer’s test‚ Bromine test light‚ Bromine test dark‚ and Tollen’s test. In Bayer’s test‚ only Acetylene‚ Eugenol and Unknown hydrocarbon 2 reacted positively and the rest retain the purplish color of KMnO4. On the other hand

Polymerization reaCTIONS polymers are high-molecular-weight compounds‚ fashioned by the aggregation of many smaller molecules called monomers. Ex. plastics that have so changed society and the natural and synthetic fibers used in clothing are polymers. Classification of polymers Homopolymers - consist of repeated long chains or structures of the same monomer unit. Ex. PVC(polyvinyl chloride) Copolymers - polymers that consist of more than one molecule. Trimers - molecules consisting

Chemical Reactions Chemical reactions happen in almost everything around us. Reactions are very important in everyday life‚ and science. Chemical reactions are the changing of substances to other substances by the breaking of bonds in reactants and the formation of new bonds in products. There are different types of chemical reactions such as combination reaction‚ decomposition reaction‚ single-replacement reaction‚ double-replacement reaction‚ and combustion reaction. Combination
