Micro-Reactions: Predicting the Products of Double Replacement Reactions Introduction – A double replacement reaction is a chemical reaction between two compounds where the positive ion of one compound is exchanged with the positive ion of another compound. If you have the reactants of two reaction solution that you can determine the products. All you need to do is pair the positive parts of the compounds with the other compounds negative part. Once you find the products you can determine their

DATE PERFORMED: JULY 20‚ 2007 SPECTROPHOTOMETRIC DETERMINATION OF EQUILIBRIUM CONSTANT FOR A REACTION ABSTRACT UV-VIS spectrophotometry is one of the most widely-used methods for determining and identifying many inorganic species. During this experiment‚ this spectrophotometry was used to determine the equilibrium constant‚ Keq‚ of the Fe3+(aq)+SCN-(aq)↔ FeSCN2+(aq) reaction. By determining the amount of light absorbed‚ the concentration of the colored FeSCN2+ solution was also quantitatively

Experiment 1 : Redox Titration Using Sodium Thiosulphate Abstract This experiment is to determine the concentration of oxidizing solution using the iodine/ thiosulphate titration where the reducing solution is potassium iodate solution and the oxidizing solution is sodium thiosulphate solution. Potassium iodate solution which is an oxidizing agent is added into an excess solution of acidified potassium iodide. This reaction will release iodine. Potassium iodide is acidified with sulphuric acid

A Penny Saved Is Two Pennies Wasted The United States of America‚ despite its relatively short life‚ is immersed in tradition. While some of these traditions are well-known and apparent‚ others are less obvious. The penny‚ our little copper one-cent piece littering change jars from coast to coast‚ is a tradition that‚ while seemingly harmless‚ is a great burden to our country. Due to the lost profits in the creation of today’s one-cent piece and using the models of previous successful countries

Is displacement a likely outcome of any situational crime prevention initiative? The short answer to this question is no. I will illustrate this answer in more detail by drawing upon three required readings. In his paper‚ Eck (1993‚ pp. 527) explicitly indicated that “there is no evidence of greater than 100% displacement and that full displacement is unlikely.” By summarizing pioneers’ works on the displacement‚ Eck listed six types of displacement: temporal‚ spatial‚ target‚ method‚ crime type

Tribal Displacement and Human Rights Violation Introduction After the Independence‚ India was engaged in a nation-building process. Nation building was equated with modernization and fast development of infrastructure and economic conditions of the people and the country as a whole. The question is that the development activities should give space for the protection of the rights of the Tribal people and the prosperity or greater good for the larger numbers? The pursuit of development has in present

Information: A double replacement reaction is a chemical reaction that usually takes place between two aqueous ionic compounds. In the reaction‚ the cation of one compound replaces the other compound’s cation that yields two produce two new and different compounds. A precipitation reaction is a chemical reaction in which the formation of a solid‚ as one of the products‚ arises “when two solutions are mixed”(Zumdahl‚ Decoste 184). This solid is also known as the precipitate of the reaction. One type of
