3 Single replacement reaction: Atoms of an element replace the atoms of a second element in a compound.

4 Activity series of metals: A list of metals in order of decreasing reactivity. A reactive metal will replace any metal listed BELOW it in the chart Its on the back of your periodic table!

5 ANSWER THE QUESTION Magnesium can not replace which of the following metals? A. Zinc B. Mercury C. CalciumCalcium D. IronIron

6 True or false? Potassium can replace sodium, zinc, and mercury? Lead can replace lithium? TRUE FALSE

7 A non-metal can also replace another non- metal from a compound. Replacement is usually limited to halogens. Their activity decreases as you move down the column. ITS JUST LIKE THE CHART OF METALS. SAME CONCEPT!

8 Bromine can replace Iodine and Chlorine? FALSE Fluorine can replace Chlorine and Astatine? TRUE

9

10 Mg(s)+LiNO 3(aq) No reaction Zn + CuCl 2 ZnCl 2 + Cu Cl 2 + NaBr NaCl + Br 2

11 Mg(s)+Zn(NO 3 ) 2 (aq) ? For more on single replacement reactions visit this site!

12 In galvanized steel, when the steel starts to corrode after the coating has been scratched, the zinc in the coating will undergo a single replacement reaction with the steel, forming zinc ions and iron atoms. Rust would be converted back to iron, in other words. Another example occurred in the Statue of Liberty. The outer layers of the statue are made of copper, but the inner support was made of steel. When the copper started to react with air, forming a verdigris coating, a single replacement reaction caused the iron to convert the copper back to copper metal; the iron started to rust, and the entire inner support had to be replaced in the 1980s AAwRqJj Facts found from here
