Abstract: In this lab, we found out how reactive and how un-reactive certain metals are. We also found out how those certain metals reacted when coming into contact with certain nitrate solutions. We noticed the chemical properties and the physical properties in the changing of the metals. The least reactive metal was Copper, which only reacted to one of the three solutions. Magnesium and Zinc were equally reactive when coming into contact with the solutions. 
    Metals  Observations  Results 

    1 Cu Has luster 1, 3, & 4. Nothing Changes 

    2. Turned black
    1 = Cu Nitrate
    2 = Ag Nitrate
    3 = Zn Nitrate
    4 =  Mg Nitrate
    2 Mg Silver color  1.Became bubbly 

    2.Turned black

    3. No reaction

    4. No reaction

    3 Zn Skinny and malleable  1. liquid turns foggy and green 

    2. Turned black

    3. No reaction

    4. No reaction

  1. Mg
  2. Cu4) 
  3. None it is not reactive.
4) 1.Zinc 2.Magnesium 3.Copper
5)A.The outer layer of a penny is made of copper because it is lustrous and more appealing to use as currency also because copper is less reactive than zinc, so it acts as a protective layer for the inner layer of a penny.

 B.Silver, because it has the same type of color as most coins, it is malleable, and is more lustrous than copper. 

C.Because it is much more valuable than copper.


6) a.Zinc because it is the most reactive     

   b.Copper because it is the least reactive  

7) a. Yes because the one of the substances was unreactive with the solutions and nothing happened to it. 

   b.The first solution with all of them since nothing happened.
