It was helpful but I needed more info on which refining process is used for iron, like smelting, electrolysis or displacement so I could use it for my school project. Byanon3188— On Aug 16, 2007 I found this subject helpful for my school project but I need more information like what ...
Sulphate-reducing microorganisms have key roles in the biogeochemical cycling of sulphur, carbon, nitrogen and metals, as well as great biotechnological potential. Here, Zhou and colleagues describe recent applications of 'omics' tools to study the stres
Alchemists in the Middle Ages developeda method combining green vitriol (iron sulphate, FeSO4, 7H2O) with nitre and water over heat in a glass or stone pot. The result was called oil of vitriol due to its oily consistency. What is green vitriol and write its chemical formula?
B.Using high purity soda ash, the soda ash which ChoiceChem use has an alkali content of more than 99.2%, and NaCl content of less than 0.97%. Our high purity soda ash help us produce higher purity sodium sulphite, and can avoid impurities (like Cl and Iron), which allows our ...
Describe the metallurgy of iron. The iron formed in a blast furnace is called pig iron, which contains impurities that make the metal brittle. What are these impurities, and how did they come about? Explain what is the metal used to extract copper from the solution of copper sulp...
Is there a chemical reaction to generate a chormophore (a colored indicator, even in the UV or near IR.) This process is not clear: the ions listed give a clear solution. Offhand, only copper salts or iron salts, present as a trace in nutrient solutions have any visible light ...
A sample of water was observed to have peculiar taste. The taste may be caused by chloride ions or sulphate ions. How can you determine which ion is responsible for the taste? Identify which solutions you would need for your experi...
to produce high yields, but too much water will lead to disease and rot. To avoid overwatering, give your onions about one inch of water everytime you irrigate. Use your finger to gauge whether or not your onions need watering by sticking it down into the soil. If you can’t feel ...
Enzymes are proteins used to make chemical reactions inside the body go at a much faster rate so that the desired products can be produced in an appropriate length of time. There are many enzymes in the body and they are used in various pathways....
