INTRODUCTION 1.1. Nickel Nickel is a chemical element with atomic number 28. It is denoted by the symbol ‘Ni’ and is one of the main constituent of meteorites. It was discovered in 1751, by Axel Fredrik in Sweden. It belongs to the transition metal group and is known for its hardness and ductility. Significant chemical reactivity is exhibited by pure Nickel. Nickel in its pure or low-alloy form is used in several fields as it is highly resistant to various reducing chemicals. Nickel when annealed exhibits
Lab Report Magnetism Introduction Magnetic objects are made with magnetic materials. Examples of magnetic materials are: iron, nickel and cobalt. Examples of magnetic objects: refrigerators, freezers, radiators, paperclips, etc. These objects are created to make our lives a little simpler and to keep us entertained. This experiment is all about magnetism. The materials we will use for this experiment are batteries with different voltages, iron nails, alligator clips and copper wires. The purpose
It further reports that we no longer can maintain a fragmented, reactive approach to sustainability and CSR activities. "Companies can choose to see this agenda as a necessary evil—a matter of compliance or a risk to be managed while they get on with the business of
n-butyraldehyde and isobutyraldehyde is 3. The reaction processes at 0.7-3MPa and 80-120°C, when rhodium is used as the catalyst. The products ratio of n-butyraldehyde and isobutyraldehyde of 8-16 can be achieved. The catalysts of nickel or copper in gaseous phase or nickel in liquid phase are used for hydrogenation. Second process is aldol condensation, in this reaction; two molecules of acetic aldehyde condense by dehydration. The product crotonaldehyde is then transformed into n-butanol by hydrogenation
