It is only 2% sucrose at first and to make it into sweet maple syrup, you have to make that percentage higher and the percentage of water lower. This is done through heat-an evaporator. The sap then has a sweet smell. This is a chemical reaction because  the aroma changes along with its chemical makeup-percentage of what's in it.]]> 2021-04-19 15:35:04 UTC https://padlet.com/allysonshapiro2025/z7emx0bvvpr21uuj/wish/1433680707 Elephant Toothpaste allysonshapiro2025 https://padlet.com/allysonshapiro2025/z7emx0bvvpr21uuj/wish/1433796805 2 H2O2 (aq) → 2 H2O (l) + O2 (g)
Elephant toothpaste is when sodium iodine reacts with hydrogen peroxide by removing an oxygen atom. This creates a substance that is similar to foam, therefore changes the chemical formula and substance as a whole.]]> 2021-04-19 15:56:26 UTC https://padlet.com/allysonshapiro2025/z7emx0bvvpr21uuj/wish/1433796805 Blue Bottle Demonstration allysonshapiro2025 https://padlet.com/allysonshapiro2025/z7emx0bvvpr21uuj/wish/1433826051 CH2OH-(CHOH)4-CHO + ½O2 → CH2OH-(CHOH)4-CO2H
The Blue Bottle Demonstration is when you shake a solution filled with a solution of glucose, sodium hydroxide, methylene blue and distilled water. The oxygen goes into the methylene when you shake it causing it to oxidize. When you stop shaking, the oxygen leaves the methylene causing it to change back to not having a color. This is a chemical change because the oxygen atoms and methylene atoms bond causing a new color.]]> 2021-04-19 16:02:05 UTC https://padlet.com/allysonshapiro2025/z7emx0bvvpr21uuj/wish/1433826051 Photosynthesis allysonshapiro2025 https://padlet.com/allysonshapiro2025/z7emx0bvvpr21uuj/wish/1435913047 6CO2 + 6H2O → C6H12O6 + 6O2
Photosynthesis is when water and carbon dioxide molecules are converted through light energy that is captured by chlorophyll. This is a chemical reaction because when this happens, a new substance is formed called glucose and oxygen.]]> 2021-04-20 02:05:06 UTC https://padlet.com/allysonshapiro2025/z7emx0bvvpr21uuj/wish/1435913047 Thermite and Ice allysonshapiro2025 https://padlet.com/allysonshapiro2025/z7emx0bvvpr21uuj/wish/1460097693 3Fe(s)+4H2O(g)→Fe3O4(s)+4H2(g)
When you perform the thermite reaction on a block of ice, it causes an explosion. This is because when heat is applied to thermite, it oxidizes causing the explosion. This is a chemical reaction because the temperature changes throughout the entire experiment of both the thermite and the block of ice.

This experiment is when potassium iodate, malonic acid, and hydrogen peroxide all chemically bond to make a dark black color. This is a chemical change because the substance is colorless at first, but then creates a new color by the end.]]> 2021-04-26 15:34:03 UTC https://padlet.com/allysonshapiro2025/z7emx0bvvpr21uuj/wish/1460115758 Hot Ice or Sodium Acetate allysonshapiro2025 https://padlet.com/allysonshapiro2025/z7emx0bvvpr21uuj/wish/1460144609 CH3COONa
This experiment is when you pour supercooled sodium acetate-sodium acetate that is still a liquid below its freezing point-onto any surface and it creates crystal shapes and other ice-looking solids. This is a chemical reaction because the liquid sodium acetate turns into a solid as its chemical formula changes. ]]> 2021-04-26 15:39:04 UTC https://padlet.com/allysonshapiro2025/z7emx0bvvpr21uuj/wish/1460144609 Magnesium and Dry Ice Reaction allysonshapiro2025 https://padlet.com/allysonshapiro2025/z7emx0bvvpr21uuj/wish/1460185191 2 Mg(s) + CO2(g) → 2MgO(s) + C(s)
When magnesium is ignited, it causes a bright white and produces a fire. This is a chemical reaction because the magnesium turns into fire without oxygen and cannot be reversed back into the magnesium. ]]> 2021-04-26 15:46:20 UTC https://padlet.com/allysonshapiro2025/z7emx0bvvpr21uuj/wish/1460185191 Fruit Rotting allysonshapiro2025 https://padlet.com/allysonshapiro2025/z7emx0bvvpr21uuj/wish/1460192638 When a fruit rots, it produces a very gross smell, when before it had a sweet and fresh smell. This is a chemical reaction because you cannot un-rot a fruit and the smell completely changes as well.  ]]> 2021-04-26 15:47:31 UTC https://padlet.com/allysonshapiro2025/z7emx0bvvpr21uuj/wish/1460192638 Sugar Snake allysonshapiro2025 https://padlet.com/allysonshapiro2025/z7emx0bvvpr21uuj/wish/1474859307  C12H22O11(s) + 12 O2(g) → 12 CO2(g) + 11 H2O(g)
This experiment is when sucrose mixed with sulfuric acid that produces carbon and steam. The carbon forms a steam that overflows out of the beaker creating a sort of a "black snake". This is a chemical reaction because  the chemicals bond creating a new substance.]]> 2021-04-29 17:02:34 UTC https://padlet.com/allysonshapiro2025/z7emx0bvvpr21uuj/wish/1474859307 Cold Pack allysonshapiro2025 https://padlet.com/allysonshapiro2025/z7emx0bvvpr21uuj/wish/1490340187 NH4NO3+heat →NH4NO3
Calcium Oxide reacts with water to produce Calcium Hydroxide and heat. This is a chemical reaction because the reactants produce heat-exothermic.]]> 2021-05-04 15:58:55 UTC https://padlet.com/allysonshapiro2025/z7emx0bvvpr21uuj/wish/1490340187 Copper and SIlver Nitrate allysonshapiro2025 https://padlet.com/allysonshapiro2025/z7emx0bvvpr21uuj/wish/1492359990 2AgNO3+1Cu →2Ag+1Cu(NO3)
This experiment is when silver nitrate reacts with copper to produce silver and copper nitrate. Copper nitrate is a solid substance, proving that this is a chemical reaction.]]> 2021-05-05 03:18:38 UTC https://padlet.com/allysonshapiro2025/z7emx0bvvpr21uuj/wish/1492359990
