Apple's iPhone charger crams a lot of technology into a small space. Apple went to extra effort to provide higher quality and safety than other name-brand chargers, but this quality comes at a high cost.. In fact, Apple seems to squeeze an awful lot of technology into a very, very small space.

To study the chemical reaction of an iron nail with aqueous copper sulphate. solution; and to study the burning of magnesium ribbon in air. (a) Chemical reaction of iron nail with copper sulphate solution in water. THEORY. Iron displaces copper ions from an aqueous solution of copper sulphate. It is a single displacement reaction of one metal by another metal. Iron is placed above copper in the activity series. Elements placed above in this series are more reactive than those placed below them. Thus iron is more reactive than copper. In this reaction, metallic iron is converted into ferrous ion (Fe2+) and
