Change of pace Messi changes his pace really well. He starts slow and runs directly at the defender which means the defender has to stop & focus on him. When he reac...
Chemistry - Copper Introduction Copper is a soft, ductile, and malleable metal. Copper has very high thermal and electrical conductivity. The symbol of copper is ‘Cu’ and atomic number is ’29.’ Copper is known to people since (about) c. 8000 BC. Copper is the first metal, which was smelted from its ore around c. 5000 BC. Salient Features of Copper Copper was the first metal that cast into a shape (in a mold). Copper was the first metal that successful alloyed with another metal, e.g. copper alloyed with tin and resultantly bronze is prepared. It is done about c. 3500 BC. First metal to be purposefully alloyed with another metal, tin, to create bronze, c. 3500 BC. Copper has a natural reddish-orange color; it is visible once the its surface is exposed. Copper is a very good conductor of electricity and heat. Copper is an element of group 11 of the periodic table. Copper normally does not react with water; however, it does react slowly with atmospheric oxygen and form a ...
