Nickel is one of the most important elements on the periodic table. It has plenty of history‚ as well as a huge importance to society. Its has unique chemical‚ physical‚ and geological properties. Nickel is used commercially in abundance‚ as it is used anywhere from simple art products such as ceramics to complex structures such as tubing for desalination plants. It is even used in the American five-cent coin‚ the "nickel".<br><br>Nickel was discovered by Axel Fredrik Cronstedt‚ in Sweden‚ during

Eggs are a key ingredient used to make a foam. Investigate the functional and chemical properties of eggs and other ingredients when making meringue. Chemical and Functional properties of eggs: Background information Eggs give a smoother texture to microwaveable dishes‚ frozen dishes are better to freeze. The yolk and the egg white cam be used in many different ways for different products of food. Eggs contain a lot of protein and a balance of other nutrition. Some producers require fresh eggs to

Lab Report Experiment #3 Chemical Aspects of Life The objective of the Reducing Sugar Test was to test if the substance has a reducing sugar in it by adding Benedict’s solution and heating it‚ there would be a color change if a reducing sugar is present‚ or it will remain blue (no reducing sugar). The objective of the Starch test was to test for starch in substances by using Iodine. The iodine will cause a substance to turn to a dark blue color if it is positive for starch. The objective for

This experimental procedure uses compounds from spinach leaves that are exposed to chromatography‚ TLC plate to indicate the different pigments within the spinach extract. ‘Column chromatography in chemistry is a method used to purify individual chemical compounds from mixtures of compounds’ (Wikipedia‚ 2011). This method is similar to thin layer chromatography‚ but the compounds in the mixture are collected separately. Green dye is used in this experiment that consists of blue and yellow constituents

Experiment 7: A Study of Chemical Changes: Types of Chemical Reaction INTRODUCTION Chemical changes are results of chemical reactions. All chemical reactions involve a change in substance and a change in energy. They are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products. There are different types of chemical reaction classified into 4 general types‚ namely‚ Synthesis‚ Decomposition

SWOT Analysis of the New Zealand Chemical Manufacturing Industry STRENGTHS Local manufacturers have: Better understanding of market conditions e.g. weather variations / seasonal changes. Better understanding of issues being treated e.g. local weed types to be controlled and chemicals to specifically target them. Ability to supply short shelf life products e.g. suspensions where imported products may expire before arrival. Local staff working for New Zealand owned companies who may be more committed

INTRODUCTION Sugar is one of the main food items consumed in Sri Lanka. The annual per capita consumption of sugar in Sri Lanka is around 30 kg and the total annual requirement of sugar in the country is around 550‚000t. But‚ only about 50‚000 t are produced locally. In a year only 38‚000 t were produced. The balance requirement has to be imported. The total annual expenditure on sugar imports is around Rs. 20 billion. Sugar cane (Saccharum officinarum) is the only crop cultivated in Sri Lanka
