Here is a video that shows that it was a chemical reaction with effervescence. joshuaradis2021 https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156528940 We know this is a chemical reaction because a new substance was formed in the fizz. The new  products are liquid water (H20), carbon dioxide gas (CO2), and solid table salt (NaCl).]]> 2017-02-27 19:05:31 UTC https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156528940 This picture is of fizzes. Effervescence shows a chemical reaction. joshuaradis2021 https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156531359 2017-02-27 19:11:46 UTC https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156531359 In part 3 of "Where's The Evidence" a precipitate was made. A precipitate is also known as a solid. dberesid https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156533025 In the lab we mixed.. These two liquids changed into a solid precipitate. The new solid substance is CuCO3(s). ]]> 2017-02-27 19:15:47 UTC https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156533025 This picture shows what a precipitate looks like. joshuaradis2021 https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156544143 The test tube all the way on the right shows a solid that formed and went to the bottom. When two liquids are mixed together and creates a solid, you know a new substance was formed.]]> 2017-02-27 19:44:05 UTC https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156544143 Endothermic dberesid https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156546617 An endothermic reaction consumes heat during a reaction.

While an egg cooks, it absorbs the heat in order to be ready to eat. This is an example of an endothermic reaction.]]> 2017-02-27 19:50:33 UTC https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156546617 Exothermic dberesid https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156546653 An Exothermic reaction releases heat during the reaction. 

A nuclear explosion is an example of a high exothermic reaction. During the explosion, heat and energy are given off at extremely high rates.]]> 2017-02-27 19:50:38 UTC https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156546653 Every chemical equation shows a chemical reaction. dberesid https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156548514 The reactants are on the left and show what the reaction begins with. The products are on the right and show what final substances are made. ]]> 2017-02-27 19:56:21 UTC https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156548514 In every chemical reaction a substance is made. joshuaradis2021 https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156558531 The formation of gas (effervescence), aromas, color changes, temperature changes, or solid precipitates can prove a chemical reaction. ]]> 2017-02-27 20:28:26 UTC https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156558531 In "Where's The Evidence", the Sugar +heat part showed an aroma when the sugar was heated. This caused the sugar to raise in temperature and release an aroma. zacharypomerantz2021 https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156564626 2017-02-27 20:49:17 UTC https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156564626 A color change is a large indicator that a chemical reaction has occurred. The new substance can very easily be a different color. zacharypomerantz2021 https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156564860 2017-02-27 20:50:12 UTC https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156564860 A Temperature change is yet another way to tell if a chemical reaction has occured. There are two types of temperature changes during a reaction, endothermic and exothermic. zacharypomerantz2021 https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156591264 2017-02-27 23:33:40 UTC https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156591264 When bacon is cooked, it releases an aroma. This is a sign of a chemical reaction. zacharypomerantz2021 https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156785564 2017-02-28 16:50:27 UTC https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156785564 Also in the "Where's The Evidence" lab, there is a color change evident. This happened because the sugar turned golden yellow-brown from the heat. zacharypomerantz2021 https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156785812 2017-02-28 16:51:18 UTC https://padlet.com/joshuaradis2021/ff2i90qdmbnm/wish/156785812
