Renee Montaque 1.2 M2 Why copper is used in electrical cables Mobiles have lots of different metals in them for example, Copper is used for electrical circuits and they are good conductors. Silver is used for switches on a circuit board and phone buttons because it's a really great conductor. Gold is used for the surface of the circuit board and a connector. Tantalum is used in electronic components and it allows scientists to make small mobiles and phones have palladium, aluminium and

in the market? How is the technology of production of molybdenum? Considering the point of view of AMAX, the main players involved in the market are (1) molybdenum producers – direct competitor like other mines or base metal companies that produce it as by-product, (2) the metal exchanges where prices are set, (3) the distribution channels, (4) the high performance steel manufacturers (the direct clients of molybdenum), and (5) the companies that produce goods partly composed by molybdenum. Besides

contain small amounts of additives, e.g., anti-foaming agents, surfactants, etc. [0009] The present invention is further directed to a method for improving How of poWdered metal borohydride salts, and to a solid composition having improved ?oW. Addition of at least 2.5% of at least one base to at least one metal borohydride prevents clumping and caking of the cells. solid. In one embodiment of the invention, at least 3% of a [0003] Borohydride-containing compositions are knoWn

Metal is a chemical element displaying certain properties by which it has the ability to conduct heat and electricity. The metals comprise about two thirds of the known elements. Some metals, including copper, tin, iron, lead, gold, silver, and mercury, have been around for many years, so long, that they were known to people in ancient times. Copper is probably the oldest known metal, known to humans. Metals differ so widely in hardness, tensile strength, density, and melting point that a definite

compare single and double displacement reactions. Hypothesis: If a metal element is mixed with an ionic compound, one metal will displace the other to create a new ionic compound. If 2 ionic compounds are mixed together, then the metals will displace each other, creating 2 new ionic compounds. Materials: Goggles, large well plate, steel wool, scoopula, 4 small beakers, dropper, 4 pieces of magnesium ribbon, 4 pieces of zinc metal, 4 pieces of copper wire, copper (II) sulfate solution, zinc nitrate

Naturally occurring metals Copper, silver, gold and platinum are the four most un-reactive metals. This means that they do not form compounds and can exist as simple lumps of the metal in the rock. They can be found native. These are easy to extract since they can be mined. Also, you can even find pieces of gold in streams. More reactive metals are not found in lumps and must be extracted from the rocks in which they occur. Roasting in oxygen For all this extraction processes, the rock must

the disadvantages of copper mining outweigh the advantages of the metal to society? Copper is one of the most important, irreplaceable metals implemented in today’s society. It has an atomic number of 29 (29 protons, 29 electrons, 35 neutrons), a relative atomic mass of 63.546 amu (see Figure 1), a melting point of 1084.62°C and an electron configuration of [Ar] 3d10 4s1 (see Figure 2). Copper is a tough, ductile, malleable metal that possesses extremely high thermal and electrical conductivity
