When it is mixed, it creates a new substance: carbon dioxide. It also bubbles up and fizzes. ]]> 2018-03-08 16:30:50 UTC https://padlet.com/faelinmills2022/n3vz9wa0wi2p/wish/239754935 faelinmills2022 https://padlet.com/faelinmills2022/n3vz9wa0wi2p/wish/239769553 In the video not only does the reaction fizz but it also makes a smell. Lemon juice smells sour and baking soda doesn't really smell like anything, so it produces a lemony smell.]]> 2018-03-08 16:51:39 UTC https://padlet.com/faelinmills2022/n3vz9wa0wi2p/wish/239769553 faelinmills2022 https://padlet.com/faelinmills2022/n3vz9wa0wi2p/wish/239774547 The bread and heat produce both a color change and an aroma. Before the bread is heated, it does not really have a smell. After it's heated, it smells kind of burnt. ]]> 2018-03-08 16:58:57 UTC https://padlet.com/faelinmills2022/n3vz9wa0wi2p/wish/239774547 faelinmills2022 https://padlet.com/faelinmills2022/n3vz9wa0wi2p/wish/239777169 The sugar and caustic soda solution is clear. The potassium permanganate solution is brown or black. When they mix, the substance turns light purple. ]]> 2018-03-08 17:03:07 UTC https://padlet.com/faelinmills2022/n3vz9wa0wi2p/wish/239777169 faelinmills2022 https://padlet.com/faelinmills2022/n3vz9wa0wi2p/wish/239941233 When the 2 chemicals are mixed, the thermometer goes down. The temperature is decreasing. The mixture also bubbles up.]]> 2018-03-08 22:02:28 UTC https://padlet.com/faelinmills2022/n3vz9wa0wi2p/wish/239941233 faelinmills2022 https://padlet.com/faelinmills2022/n3vz9wa0wi2p/wish/239943271 When the lead nitrate is mixed with the sodium iodide, it turns into a bright yellow solid.

There were flames coming out of the new substance.]]> 2018-03-08 22:16:13 UTC https://padlet.com/faelinmills2022/n3vz9wa0wi2p/wish/239945198 faelinmills2022 https://padlet.com/faelinmills2022/n3vz9wa0wi2p/wish/239950073 In the picture, the magnesium ribbon was dropped into the hydrochloric acid. Once that happened, the HCl started fizzing and bubbling up. ]]> 2018-03-08 22:35:54 UTC https://padlet.com/faelinmills2022/n3vz9wa0wi2p/wish/239950073 faelinmills2022 https://padlet.com/faelinmills2022/n3vz9wa0wi2p/wish/239952026 The picture shows what happens when ammonia and copper sulfate are mixed.
