Overall, the experiment was a success. Fewer mistakes were made and everything went smoothly. The first reaction was Magnesium ribbon in which we were able to examine it reacts when we put it under the flame. It is important to remember to use the tongs that are not prone to melt like the rubber pair I started to use. I quickly paused the experiment once I noticed the rubber tongs were gluing together. This minor mistake is avoidable and easy to fix. Our first conclusion was that magnesium burns to form new compounds. It reacts with oxygen to form oxides of each metal. This was an example of combustion and combination/synthesis reactions. Next, was the CuCO3 reaction, where we used a wood splint to discover that CO2 gas was present. After we …show more content…
It began to fizz instantly and the metal turnings began to dissolve. The bubbles continuously moved up and down while there was also a formation of a gas. We then placed a second test tube over the reaction test tube, and in order to see if it was Hydrogen gas that was present, we had to insert a burning wood splint into the tube and wait to hear the pop noise. This abrupt pop scared me and Julia so much we screamed and flew back. At least we discovered the presence of Hydrogen gas! This is an example of single replacement reaction. Next, is the AgNO3 reaction where we placed a small coil of copper wire into the solution. In approximately 8 minutes we got our reaction. The copper is covered with what looks like white crystals and the AgNO3 solution turned clear light blue. This is an example of single replacement reaction. Here comes another reaction, and this time it involves copper (II) sulfate solution and sodium hydroxide solution. When the two aqueous solutions mixed with each other, a pale blue precipitate of basic copper hydroxide and a solution of sodium sulfate is formed. Lastly, is the reaction between sodium carbonate and
