In class today, Andrew led a guided lab to help us learn about chemical reactions and combustion. To prepare for the experiment we were going to do, we took notes on the structures of atoms. We also learned how to use the periodic table to find out how each element will react to another. By using the periodic table, we also learned how to find out how many electrons are going to be in the outer shell of the atoms for the element. In order to prepare for our experiment, we also found out how atoms bond with each other based on the amount of electrons each has on its outer shell by taking notes. When learning this, we looked at how hydrogen and oxygen bonded because our expirement was going to be about bonding hydrogen and oxygen.
Looking Back:
My groups experiment ended up turning out really well. When we put the magnesisum in the citric acid and water mixture, we were able to collect a decent amount of hydrogen in the balloon. Also when we put the hydrogen balloon over the lit candle, out balloon exploded with a decent sized flame explosion. It looked really cool because we turned out all the lights in the room so that everyone could see the explosions better. When the balloons exploded, they also created a loud noise. We noticed that the more hydrogen in a balloon, the louder the explosion is. When we were putting the magnesium in the glass with the citric acid and water, the mixture started bubbling a lot. The more that it bubbled, the hotter the vial became. Also, the longer the magnisium stayed in the mixture, the more is starter to bubble and disintegrate into the mixture. When we touched the bottom of the glass, we noticed that it was really hot.
Looking Forward:
One reason the hyrdogen and oxygen molecules exploded when they touched was because the electrons kept jumping from the outer shell to an even outer shell. They were the color orange when the explosion happened because each element exploded as a different color, like how fireworks are different colors. This expirement made me wonder what elements are in the candles that have blue or green flames. It also made me wonder what exactly makes an element have a distinct color when it explodes.
Looking Inwards:
I think we got desirable results with our expirement. The first reason is because we successfully collected hydrogen in the balloon from the magnesium. The other reason is because the balloon exploded with an orange flame and created a small amount of water on the plate. I think I performed well because I worked together with my group. I stayed on topic and helped conduct the expirement.
Looking Outward:
For this expirement, I worked with Zoe, Monique, Rebekah, and Fatuma. I think all of us performed really well during the expirement. We all worked together well and contributed equal amounts of effort. I contributed by pouring the water into the vial with the citric acid. I also contributed by documenting a lot of the expirement through videos. Lastly I contributed by being the person for our group to set the balloon over the flame.
Looking Forward:
If I could do this again, I would like to try maybe using different elements to try to get a different colored explosion. Also maybe use more magnesium to get more hydrogen for the balloon. If I was organizing a group for a lab, I would probably work with the same people because we all seemed to work together really well. I think I see a way to continue this experiment by testing out different elements or by trying to see how hydrogen reacts with other elements.
Below is a video Zoe made of our group's experiment and how it turned out.
