 * Aluminum || When the acid was put in some Al came out. I then quickly changed into a solid. The solid turns in to powder form again but others look like they’re melted and it keeps the aluminum in one place || 3 || <span style="font-size: 10pt; mso-bidi-font-family: 'Times New Roman'; mso-fareast-font-family: 'Times New Roman';"> [] ||
 * Copper || When HCL is put in some of the copper powder goes to the surface of the liquid. The rest stays on the bottom of the test tube. || 5 || <span style="font-size: 10pt; mso-bidi-font-family: 'Times New Roman'; mso-fareast-font-family: 'Times New Roman';"> [] ||
 * Iron || Nothing happens when acid is first put it. Bubbles start to create. HCL’s color starts to change (from clear to light grey/fade-ish). More bubbles are created as the time passes.
 * Magnesium || When the acid is put in the temperature of the liquid increased. Lots if bubbles were created and the powder still goes up. The liquid turned from clear to white. || 1 || <span style="font-size: 10pt; mso-bidi-font-family: 'Times New Roman'; mso-fareast-font-family: 'Times New Roman';"> [] ||
 * Zinc || When acid was put in the liquid immediately turned dark grey. Now Some of the zinc is on the surface of the liquid (creating bubbles) and the rest is on the bottom of the test tube, also creating bubbles. Some bubbles are moving up.

From the five metals given, we magnesium was the most reactive and copper was the least. 2. The theory about the 3 elements aluminum, iron, and magnesium were incorrect. The theory used was that the more valence electrons the element has, the more reactive the element will be. For example, when the element has to be changed to its full state, it will be easier to take away 1 electron from hydrogen then it will be to add 7 electrons to chlorine. 3. Aluminum theory was wrong because aluminum is actually more reactive than copper, zinc and iron because the 3 elements are transition elements. The actual amount of ions for transition metals isn’t known which makes aluminum more reactive than the transition metals. The published data says that magnesium is the most reactive, then aluminum, then zinc, iron, and finally copper. The data from the lab says that magnesium is the most reactive, then zinc, then aluminum, then iron and finally copper. 4. Out of the five metals, magnesium was the most reactive. Since it is placed in the second column in the third row, it will have the least ions. The less amount of atoms that have to be given, the more reactive the metal will be. For example, it will take faster for a beryllium to change to its full state then it will be for a nitrogen because it will take faster to take away 2 electrons (beryllium) than gain 3 (nitrogen). In conclusion, the less amount of ions the element makes (in other words, the less electrons that have to be given) the more reactive the element will be. Transition metals are unsure because the actual amount of ions cannot be predicted so for this lab the transition metals are known to be less reactive then the metals. "What about transition metals? We cannot predict what ion they will form" (Law) . . The data wasn’t that reliable because the measurement wasn’t perfectly accurate and the lab was done only once. This means that there could have been mistakes that weren't noticed (e.g. wrong metal, mixed metals, wrong acid).

 * Evaluation **
 * Were the lab and the experiment reliable? **


 * How valid the method was to collect the data? **

The method was easy to follow and also the right way to get the accurate answer. Although our method was base on the variables table and figured the way to get the accurate data. There was some error on our prediction but in general everything was good.


 * Improvements and weakness table **


 * Why this was a fair test**

<span style="color: black; mso-ascii-font-family: Calibri; mso-bidi-font-family: Calibri; mso-hansi-font-family: Calibri;">We filmed and could watch the video over and over again to get the observations and also, we tried to make the condition (e.g. The amount of metal, amount of HCL etc. ) the same. The error won't influence the data.
