|Element/Compound|$`Mg(NO_3)_2`$|$`Zn(NO_3)_2`$|$`Cu(NO_3)_2`$|$`AgNO_3`$|
|:---------------|:-------------|:-------------|:-------------|:---------|
|$`Mg`$|N/A|The rod has now a `black coating` around it The solution has not changed much|The rod has now gotten a `light brownish` coating around the rod, the solution has gotten a tiny bit `lighter blue`.|The rod as now gotten a very light `gray coating` around the rod. Not much change in the solution.|

|$`Pb`$|Nothing changed|The solution got lighter, into a `lighter blue`, and there is now a `orangish brownish` coating around the rod|Nothing changed|N/A|

## Observations

- **Note:** The data tables are not ordered in a specific way, they are ordered in the order appeared in the website with some minor tweaks.
- By starting looking at the first table, we can see that Ag reacts with the least amount of solutions. Since this is an good observation, lets assume that the elements that reacts the least 
in each activity are the **strongest** elements, and the opposite be the **weakest** elements (**weak and strong right now have no real meaning**), lets order the elements and see 
how they vary:

### Activity 1 Ordered Strongest To Weakest
- $`Ag, Cu, Zn, Mg`$

### Activity 2 Ordered Strongest To Weakest
- $`Pb, Sn, Ni, Fe`$

### Activity 3 Ordered Strongest To Weakest
- $`Cu Pb, Fe, Zn`$

## Observations Cont
- By combining the above 3 lists, we can get a general list of whos **weaker** and whos **strong**, as listed below:
- $`Ag, Cu, Pb, Sn, Ni, Fe, Zn, Mg`$, 
- Also, we can look at the different colours each rod makes, Copper seems to make a orangish brown coating around the rod with **weaker** elements, Iron seems to make a greyish green solution with dark gray/gray coating with **wekaer** elements.
- Elements only react with a **weaker** element.
- We can also see that **weaker** elements are more reactive than stronger **elements**
