department. Process chart of TSL‚ INDIA was first addressed. So‚ it all starts with iron ores and fluxes (limestone) to be mixed and then pelletized in a sinter plant. At the same time‚ raw coal is processed to form coke in a coke plant and then sintered pellets along with coke are fed to a blast furnace. Hot metal is obtained at the bottom of the blast furnace above which slag floats‚ both of them are tapped out. Hot Iron metal is processed in LD1‚ LD2 and LD3 (Ladles) to lower down the carbon content

copper and iron in a chemical reaction. The stoichiomentry of mass is that during the heating the experiment does loose mass .This mean that mole and mass did change. An Example of real world is Masses and volumes of products are extremely important in key reactions such as the deployment of air bags in vehicles‚ carbon dioxide production to help bread rise‚ and the Production of ammonia gas for industries. To do this lab we weighed Copper. Than we weighed the iron nail. Next‚

Redox reactions (Redox terminology‚ galvanic cells‚ standard electrode potentials‚ strength of oxidizing/reducing agents‚ corrosion and protection against it) Oxidation is defined as the loss of electrons and reduction is defined as the gain of electrons. Oxidizing agents‚ such as oxygen are defined as substances which accept electrons; reducing agents are substances which donate electrons. Redox reactions are: a) The reactions of metals with non-metals 2Na+Cl2→2Na+Cl- b) The reactions

Toppers‚ mesh‚ helmets and hoods that hang over gutters to prevent debris from accumulating in the gutters and blocking the flow of water are usually attached by homeowners with nails or screws. Unfortunately‚ putting holes in your roof for any DIY project is never a good idea because it

10‚000 years ago. A copper pendant discovered in Northern Iraq is thought to date back to around 8700 BCE. Prehistoric man probably used copper for weapon making. Ancient Egyptians appreciated the relatively good corrosion resistance of the metal. They used copper bands and nails in ship building‚ and copper pipes were used to transport water. Years later‚ copper alloys appeared. The “Bronze Age” saw the extensive use of copper and bronze for arms‚ coins‚ household utensils‚ and furniture

frequently also as the final point to reject heat into the atmosphere by evaporating inside cooling towers. Depending on the quality of available fresh water supply‚ waterside problems develop in cooling water systems from: • Scaling • Corrosion • Dirt and dust accumulation • Biological growth Any of these problems – or more usually a combination of them – result in costly unscheduled downtime‚ reduced capacity‚ increased water usage‚ high operation and maintenance costs
