process with varying the different types of Eco-friendly fluxes and conventional fluxes to study its effect on the corrosion performance & other physical properties of zinc coatings. Quality of this galvanized steel is characterized by AC impedance spectroscopy. Coating thickness was determine by coating thickness gauge while adhesively of coating were find out by bend test. Corrosion performances of coating was determined by potentio-dynamic test using Potentiostat Gammry Reference 600 & Salt spray test

In this experiment the objective was to perform a Diels-Alder reaction using cyclopentadiene and maleic anhydride to synthesize the product‚ cis-Norbornene-5‚6-endo-dicarboxylic anhydride. The Diels-Alder reaction is one of the most important reactions in organic chemistry and was first investigated by Otto Diels and Kurt Alder in Germany. It is a [4+2] concerted cycloaddition reaction which involves a diene and a dienophile. The Diel-Alder reaction are mainly used for creating new carbon-carbon

Rubidium is a chemical element that was discovered in 1861 by Robert Bunsen and Gustav Kirchhoff‚ in Heidelberg‚ Germany through a scientific process of flame spectroscopy. During the process‚ Kirchhoff and Heidelberg noticed bright red lines in its emission spectrum which caused them to choose the name Rubidium derived from the Latin word rubidus‚ meaning "deep red". Rubidium is a chemical element with symbol Rb and atomic number 37 and an atomic mass of 85.4678. Rubidium is a soft‚ silvery-white

ust imagine drinking a nice cold Minute Maid Pink Lemonade on a hot day‚ or a cold Red Powerade after a long hard practice. The cold refreshing drink rushes through your body and quenches your thirst. However‚ do you know what you are actually drinking‚ and how much of that drink is contaminated with dye? In this experiment‚ with the use of a spectrophotometer‚ the amount of concentrated dye in three drinks will be tested. First‚ the dye itself will be examined to see what the optimal wavelength
