LAB REPORT 4 DETERMINING AN EQUILIBRIUM CONSTANT CAUSION 1. Potassium thiocyanate (KSCN) is hazardous 2. Wear protective material before performing the experiment. INTRODUCTION This experiment outlines the techniques necessary to determine the equilibrium constant for the formation of an iron(III) thiocyanate complex ion (FeSCN2+) from Fe3+ and SCN- . The quantitative preparation of several solutions and subsequent measurement of the solution absorbance

First the total volume of gas that is to be stored needs to be calculated. From the mass balance it is known that 30.92 kmol of methane can be expected every hour. This correlates to 742.0 kmol/day. The ideal gas law will be used‚ with a compressibility factor‚ Z‚ to account for departure for un-idealality. An operating temperature of 50 will be assumed‚ as this is the highest feasible ambient temperature that can be expected. Also assume that the pump or compressor used to transport the methane

next step is going to be? Storing information throughout the volume of a medium‚ not just on its surface is an intriguing solution to our entire problem regarding storage. So this is it‚ Holographic Data Storage. Holographic Data Storage is a volumetric approach which‚ although conceived decades ago‚ has made recent progress towards practicality with the appearance of lower-cost enabling technologies‚ significant results from longstanding research efforts and progress in holographic recording

Aim: To Find and test the Iron content in different food sources INTRODUCTION: A Redox titration was used in order to perform this experiment. Reduction/oxidation (redox) process occurs when electrons are transferred from a donor species (the reducing agent) to another acceptor species (the oxidizing agent). It happens between an analyte and a titrant. A redox titration is done just as a normal titration is done‚ however instead of titrating an acid against a base‚ an oxidizing agent is titrated

Although the world may disagree about many issues there is a commonality that continuously unites nations from all over the world‚ and it is a fundamental system in which the world cannot function without‚ the International System of Units (SI). The SI was established in 1960 by the 11th Conference of Weight and Measures; it began with 17 nations including the United States and today has become widely used among 51 nations (Historical). The SI is a metric system of units of measurement and is predominantly
