------------------------------------------------- Alloy Steel is a metal alloy whose major component is iron‚ with carbon content between 0.02% and 2.14% by mass. An alloy is a metallic solid solution composed of two or more elements. Complete solid solution alloys give single solid phase microstructure‚ while partial solutions give two or more phases that may or may not be homogeneous in distribution‚ depending on thermal (heat treatment) history. Alloys usually have different properties from those

Also‚ in calcareous soils‚ boron‚ manganese‚ molydenum‚ zinc‚ iron greatly reduces the effectiveness of the crop often feel inadequate these nutriens.Thus‚ it is less soluble than acidic or neutral soil‚ most of the natural environment of alkaline soil are arid regions.

Robert Lawrence and Edmund Stephens‚ two graduate students of geology from Columbia University‚ organized the Saline Salt Company in 1974. Keeping in mind the fact that every 1‚000 grams of seawater contains approximately 35 grams of various salts‚ the two men pictured limitless wealth for themselves by extracting these salts. Common table salt comprises 27 grams out of each 35 grams and is easy to extract; so‚ the men decided to begin producing it. They picked New Iberia‚ Louisiana as the ideal

NAME: N. ARUN KUMAR MINERAL RESOURCES DONE BY: 1. N.ARUN KUMAR. 2.N.GAUTAM REDDY. 3.B.HARSHAVARDHAN. 4.K.VENKATESH. 5.P.TARUN. WHAT IS A MINERAL? A mineral is a naturally occurring substance that is solid and stable at room temperature‚ representable by a chemical formula‚ usually abiogenic‚ and has an ordered atomic structure. It is different from a rock

Writing ionic equations for redox reactions You can split the ionic equation into two parts‚ and look at it from the point of view of the magnesium and of the copper(II) ions separately. This shows clearly that the magnesium has lost two electrons‚ and the copper(II) ions have gained them. These two equations are described as "electron-half-equations" or "half-equations" or "ionic-half-equations" or "half-reactions" - lots of variations all meaning exactly the same thing! Any redox reaction

Chemical Formulas Review: Nomenclature and Formula Writing Naming Simple Compounds There are four naming systems you should familiarize yourself with to succeed on the SAT II Chemistry exam. The trick is recognizing which naming system to use. Here are the guidelines: * If the compound starts with H‚ it is an acid. Use the naming acids rules. * If the compound starts with C and contains quite a few H’s and perhaps some O’s‚ it is organic. Use the naming organic compounds rules. *

performed in the lab. Reaction 6: Reaction 7: The decomposition of hydrogen peroxide is an example of decomposition. In the lab‚ this was tested when we added hydrogen peroxide and a catalyst of manganese together. When a glowing splint was held over the test tube after the peroxide and manganese had time to react‚ it relit‚ proving that oxygen was present as a product of the decomposition of the hydrogen peroxide. Decomposition reactions occur when a single substance breaks down into two or

choose bottled water over tap water when quenching thirst. One reason to choose bottled water rather than tap water is because bottled water is odor free. Occasionally‚ tap water can have unpleasant odors. These odors are caused by sulfur‚ iron‚ manganese‚ and chlorine most of the time. The two types of sulfur found in tap water are sulfate and hydrogen sulfide. Both are caused by natural process happening underground.
