<span style="font-family: 'Tahoma','sans-serif';"> <span style="font-family: 'Tahoma','sans-serif';">As explained in the observations table, the most reactive substance was magnesium. After we put 0.5g of magnesium into the acid, it dissolves very quickly and bubbles come up and the test tube was really hot. Also, the balloon had air on it and it expands. We had observed each of the experiments for 2 minutes and we concluded that copper was the non – reactive substance followed by aluminum and iron. Copper didn’t really react to the acid because after 2 minutes of observing, copper stayed the same and no bubbles come up. Aluminum reacts with the acid but very slowly because there were only a few bubbles comes up and the balloon didn’t really expand. While iron also react with the acid but again, only a few bubbles comes up but this time, the balloon did expand a little. Zinc also reacts with the acid and many bubbles come up and this time, the balloon expands pretty much. A table has been drawn to see the most reactive substance to the least reactive substance. <span style="font-family: 'Tahoma','sans-serif';">In the hypothesis, we guess that the substances whose has stronger bonds will be less reactive. This is a true statement because copper has very strong bonds between them and we can’t break them apart. Through the experiment, we concluded that copper was the least reactive substance. Our hypothesis was also correct because we guessed that the substances that have weaker bonds will be the most reactive. This is also a true statement because magnesium has weaker bonds and it is easy to break them apart. As the experiment tells us, magnesium is the most reactive substance out of the 5 substances which followed by zinc, iron, aluminum and copper. <span style="font-family: 'Tahoma','sans-serif';">Ms. Law had taught us about the reactivity of the elements in the variables table. As taught, the most reactive elements come on the left of the variable tables and as the elements come closer to the noble gases group, it becomes less and less reactive. This is true in the experiment because aluminum (in the periodic table) is closer to the noble gases group and magnesium is much further so it is more reactive according to Wellen Wilkinson. <span style="font-family: 'Tahoma','sans-serif'; mso-fareast-font-family: Tahoma; msofareastfontfamily: Tahoma; msolist: Ignore;">4. <span style="font-family: 'Tahoma','sans-serif';">According to Wellen Wilkinson, all the metals in group 1 of the periodic table is slightly less reactive than potassium and the metals are less reactive than calcium.

But we didn’t repeat our results and we’re not really sure if our results were right. We wanted the 1g of each solid, but we changed to 0.5g, because we thought it’s too much, but we realized that it’s more difficult to measure. 2. The data was validity <span style="color: black; font-family: 'Tahoma','sans-serif'; mso-bidi-font-size: 12.0pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-US;">because we had chose the correct variables. But some of the variables were changed. In the experiment, the amounts of each solid aren’t all 0.5g. Some of the solids such as aluminum, we rounded it up to 0.5 g but the mass was actually 0.4 g. The dependent variable was the only thing that was measured in this experiment. The method was well set up although we had made many changes after or during doing the experiment. So, the experiment was half invalid and half valid. 3. Table showing the weaknesses and the way to improve the weakness in the method <span style="color: black; font-family: 'Tahoma','sans-serif'; font-size: 12pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-US;">

This experiment has some qualities to become a fair test<span style="color: black; font-family: 'Tahoma','sans-serif'; mso-bidi-font-size: 12.0pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-US;"> because the independent variables (the different types of solids) and the dependent variables were controlled in the experiment nicely. But, one of the most weakness in the method was that we didn’t mixed each type of solids in at the same time which made it not a fair test because we needed to observe the 5 test tubes at the same time. <span style="font-family: 'Tahoma','sans-serif'; font-size: 10pt; mso-bidi-font-size: 11.0pt;">
