Topic:  Compare the two metals Zinc and Magnesium

Introduction:

Metal Zinc and Magnesium are used widely in the world, in 20th century, Magnesium are used as producing flashing light of cameras, and today, it is more often been used to be light sources. Zinc can used to make battery because it can react with NH4Cl, and release H+ ions, and Zinc can also be used to make alloy by melting together with other kinds of metal, the alloy made is very strong and light.

Abstract:

From the period table on the test book, I found that Magnesium is located on the group IIA and Zinc is located on the group IIB. From my research on the Internet, I found that these two kinds of metal are related because they both have Roman numeral “II”. In some cases they share the same properties that atoms of these metals can combine with atoms of oxygen to form oxide, such as MgO and ZnO, and also these atoms can form salt by replacing two hydrogen atoms of an acid to form MgCl2 and ZnCl2.

Question:

What are the properties do these two kinds of metal share? What observation will happen?

Experiment group:

I designed three experiments about Zinc and magnesium:

  1. Testing the properties of Magnesium and Zinc
  2. Replacement of copper
  3. Producing hydroxide
  4. What will happen if Zn and Mg metal react with H2S acid.

Steps:

Some of the experiments are done in home, I bought materials like Magnesium and Zinc from online shopping, and also I got the chance to use chemistry lab in my mother school, so it allows me to investigate deeper.

I: Testing the property ...
