Balenced equation for Aluminium Copper → Chloride Aluminium chloride copper. In order to form copper metal and aluminium chloride aluminium interacts with copper chloride. It is because aluminium is more reactive than copper as per the reactivity of metals it displaces copper from a copper chloride solution.
Nov 30 2014 vlsi design2. In ICs the inductors can magnetically couple to the the substrate and cause eddy current to flow which causes power loss emf 2/Rsub . To minimize this people put metal copper aluminum shielding below the inductor to prevent magnetic lines of from from reaching substrate. Now the catch is both copper and aluminum have mu r =1

ALUMINUM ALKYL HYDRIDES are powerful reducing agents. Can decompose spontaneously at ambient temperature with explosive violence. Can ignite in air with or without oxygen enrichment Bretherick 1979 p. 221 . At elevated temperatures the hydride reduces carbon dioxide or sodium hydrogen carbonate to methane and ethane.
Alkyl halides are a class of compounds where a halogen atom or atoms are bound to an sp3 orbital of an alkyl group. CHCl 3 Chloroform organic solvent CF 2 Cl 2 Freon 12 refrigerant CFC CF 3 CHClBr Halothane anesthetic Halogen atoms are more electronegative than carbon atoms and so the C Hal bond is polarized.
