The picture shows the substance fizzing over the cup, a sign of a chemical reaction. This is the carbon dioxide created from mixing the two chemicals. The carbon dioxide is a new substance, and if a new substance is formed then a chemical reaction is taking place.]]> 2017-02-17 17:49:03 UTC https://padlet.com/emilycarlin2021/60a0trour7kz/wish/154655527 emilycarlin2021 https://padlet.com/emilycarlin2021/60a0trour7kz/wish/154657482 2017-02-17 17:55:17 UTC https://padlet.com/emilycarlin2021/60a0trour7kz/wish/154657482 emilycarlin2021 https://padlet.com/emilycarlin2021/60a0trour7kz/wish/154657556 When food spoils, you know a chemical reaction has happened. Once the food is spoiled, it will have a different smell than it previously had. This smell comes from the mold that makes the food spoiled. Because the food now has a different aroma, it is a new substance because of the new aroma. The new substance indicates that a chemical reaction happened.]]> 2017-02-17 17:55:34 UTC https://padlet.com/emilycarlin2021/60a0trour7kz/wish/154657556 emilycarlin2021 https://padlet.com/emilycarlin2021/60a0trour7kz/wish/154658804 2017-02-17 18:00:05 UTC https://padlet.com/emilycarlin2021/60a0trour7kz/wish/154658804 emilycarlin2021 https://padlet.com/emilycarlin2021/60a0trour7kz/wish/154658873 When flames change color because of a substance mixed with the flame, a chemical reaction has happened. The combination of the fire and the other substance result in the changing of the flame's color. This shows a chemical reaction because the previous substance (the original flame) had a different color than the new substance (the new flame), and the change in color shows a change in substance. The change in substance means a chemical reaction.]]> 2017-02-17 18:00:19 UTC https://padlet.com/emilycarlin2021/60a0trour7kz/wish/154658873 emilycarlin2021 https://padlet.com/emilycarlin2021/60a0trour7kz/wish/155244941 2017-02-21 18:06:29 UTC https://padlet.com/emilycarlin2021/60a0trour7kz/wish/155244941 emilycarlin2021 https://padlet.com/emilycarlin2021/60a0trour7kz/wish/155245216 The combination of sodium carbonate and hydrochloric acid creates fizzing. This effervescence shown coming from the two combined substances in the picture shows that a chemical reaction is happening.  The effervescence is the carbon dioxide created, as shown in the formula above. Because a new substance (carbon dioxide) was created, it means that a chemical reaction happened.]]> 2017-02-21 18:07:16 UTC https://padlet.com/emilycarlin2021/60a0trour7kz/wish/155245216 emilycarlin2021 https://padlet.com/emilycarlin2021/60a0trour7kz/wish/155248590 2017-02-21 18:15:41 UTC https://padlet.com/emilycarlin2021/60a0trour7kz/wish/155248590 emilycarlin2021 https://padlet.com/emilycarlin2021/60a0trour7kz/wish/155248872 When sugar is burnt, a chemical reaction happens. This is known because a new aroma is created. This new aroma signals a chemical reaction has happened. The new smell comes from the burnt sugar. Because the sugar previously did not have this smell, the aroma represents a new substance formed. ]]> 2017-02-21 18:16:25 UTC https://padlet.com/emilycarlin2021/60a0trour7kz/wish/155248872 emilycarlin2021 https://padlet.com/emilycarlin2021/60a0trour7kz/wish/155839799 2017-02-23 17:55:12 UTC https://padlet.com/emilycarlin2021/60a0trour7kz/wish/155839799 emilycarlin2021 https://padlet.com/emilycarlin2021/60a0trour7kz/wish/155840161 In this experiment, the liquid originally was an amber color. First the color changed to red, then green. These color changes showed electrons being transferred as the liquid reacted with the oxygen. The indigo carmine in the substance turn green when it oxidized. The red color was a transition from amber to green. There was a new color created, and that new color represented a new substance. Because a new a substance was formed a chemical reaction happened.]]> 2017-02-23 17:56:05 UTC https://padlet.com/emilycarlin2021/60a0trour7kz/wish/155840161 AndrewBender51 https://padlet.com/emilycarlin2021/60a0trour7kz/wish/156213831 In the cool light lab, there was a temperature change. In the lab, solid Barium Hydroxide and Ammonium Thiocyanate were mixed together. This created a chemical reaction. This is known because there was a temperature change. The temperature of the liquid that was formed dropped many degrees. This means that it was an endothermic reaction. There was an absorbtion of heat so the temperature dropped.]]> 2017-02-25 23:49:14 UTC https://padlet.com/emilycarlin2021/60a0trour7kz/wish/156213831 AndrewBender51 https://padlet.com/emilycarlin2021/60a0trour7kz/wish/156214083 In this demo, 50 mL of Hydrogen Peroxide was mixed with one packet of Potassium Iodide. Also, Mrs. Richardson somehow disappeared and a genie was in the room. Once the two substances were mixed, it quickly turned into foam and shot out of the graduated cylinder. In this reaction, there was a temperature change. The temperature went up. This means that is was an exothermic reaction. It released heat, so the temperature grew.]]> 2017-02-26 00:01:12 UTC https://padlet.com/emilycarlin2021/60a0trour7kz/wish/156214083 AndrewBender51 https://padlet.com/emilycarlin2021/60a0trour7kz/wish/156214615 In this demo, Sulfuric Acid was added to sugar. This resulted in a black substance that looked just like a souffle. It gave off a very bad aroma. This reaction produced not only an aroma, but it also created a new substance. This new substance was carbon. This was a chemical reaction because carbon was made, which is a new substance.]]> 2017-02-26 00:27:31 UTC https://padlet.com/emilycarlin2021/60a0trour7kz/wish/156214615 AndrewBender51 https://padlet.com/emilycarlin2021/60a0trour7kz/wish/156215083 As mentioned earlier in the aroma section, spoiled food maked a chemical reaction. However, we don't only know this because of the aroma. We also know this because of the mold that was created.

They were combined in a graduated cylinder. Once the combination occurred, there was a chemical reaction. A yellow solid (precipitate) was created, which was surrounded by a clear liquid. This precipitate proved that it was a chemical reaction.]]> 2017-02-26 01:01:55 UTC https://padlet.com/emilycarlin2021/60a0trour7kz/wish/156215509 AndrewBender51 https://padlet.com/emilycarlin2021/60a0trour7kz/wish/156215991 In this lab, Copper sulfate was added to sodium carbonate solutions.
