A. Based on your observations make an activity series of the metals used. List them in such a way that the most active metal is on the left and the least active metal is on the right. Remember‚ sodium and copper are metals‚ too. B. Suppose you inserted a piece of copper into a solution of nickel chloride and observed no reaction. Then if you inserted a piece of iron into the solution of nickel chloride a nickel deposit formed on the bottom of the well in the well plate. Where does

to be used as the essential outer material of the statue? Ancient Chinese‚ Greeks‚ and Romans found bronze to have a distinct advantage than other metals such as pure copper. As bronze being ninety percent copper and ten percent tin‚ the alloy had advantages such as: the difference in tensile strength bronze had compared to copper‚ and the low liquid melting point the alloy had in order to stay longer in this form for casting. The people during these times found many uses of this material‚ hence

Pennies may have been useful several years ago; however‚ now they are inconvenient and obsolete. As an American citizen who pays with U.S. currency almost every day and almost every day‚ inconvenienced by the use of pennies. Pennies make even less sense provided the fact that the United States Government has made such a large amount of pennies that the materials used to make pennies are worth more than a penny itself. Other countries have already done this and it is working out well for them‚ therefore
