construct a table listing the reduction potentials of a series of metal ions in order of ease of reduction. The series of half-cells is constructed by placing a piece of metal into a 1.0 M solution of its ions for each metal in the series. The metals are Cu‚ Fe‚ Pb‚ Mg‚ Ag‚ and Zn. The half-cells are connected by a salt bridge constructed of a strip of filter paper soaked in a solution of KNO3. The zinc half-cell is used as the reference standard and assigned an E of 0 volts‚ and all reduction potentials

Beginning with pure copper wire‚ this experiment will exhibit its transformation to substances including Cu(NO3)2‚ Cu(OH)2‚ CuO‚ CuSO4 . 5H2O and finally returning to pure copper (Cu). The experiment objective is to successfully complete these conversions and then calculate the percentage of recovered copper using the initial and final mass data obtained.

rates). The most famous example is the European Union (EU). Trade creation occurs when some domestic production in a union is replaced by lower-cost imports from another member nation. This increases specialization in production and welfare in the CU. A trade-creating customs union also increases the welfare of nonmembers because some of the increase in its real income spills over into increased imports from the rest of the world. Trade diversion occurs when lower-cost imports from outside the

Using three examples‚ comment on and discuss the development of French Domestic Architecture in the 17th century In 1600‚ the civil war finished in France between the Protestants and the Catholics; therefore‚ there was a need for new buildings in France. However‚ Henri IV was assassinated in 1611 and therefore Louis XIII took the throne until 1643. He had Italian influence as his mum; Marie di Medici was Italian which reflected the style of architecture that was built during his time as king.
