Cool Reactions

In this video, there are 10 reactions. I will use my knowledge taken from class to determine whether it is a reaction or is not, provide the balance chemical equation, and tell which type of reaction it is.

10. Sodium and Water in Chlorine Gas: This is a chemical reaction. The reactants, Sodium and Chlorine, create Sodium Chloride, or salt. 2Na + Cl(2) = 2NaCl, and this is a synthesis reaction.

9. Magnesium and Dry Ice Reaction: This is a chemical reaction. The reactants, Magnesium and Carbon Dioxide, and gas is produced. Dry Ice is composed of pressurized CO2, which Magnesium can burn in. 2Mg + CO2 = 2MgO + C, this is a Single Methesis replacement because Magnesium replaces the Carbon.

8. Potassium Chlorate and Candy Reaction: This is a chemical reaction. Oxygen is produced from the burning of Potassium Chlorate and the candy. This is a combustion reaction. 6KClO3 + C6H12O6 –> 6KCl + 6H2O + 6CO2 + 3O2 (I’m using glucose because of the candy)

7. Meissner Effect: This is not a chemical reaction, because this is dealing with a temperature change and magnets, causing an object to “float”. Magnets, how do they work?

6. Sodium Acetate Super Saturation: This is not a chemical reaction. The only thing that changes in the Sodium Acetate’s state. Nothing is produced.

5. Superabsorbent Polymer: This is not a chemical reaction. The polymer is just absorbing the liquid and nothing is produced from it.

4. Floating on Sulfur Hexafluoride: This is not a chemical reaction, the Sulfur Hexafluoride making objects “float” is nothing more than using it’s physical properties ( it being 5 times denser than air )

3. Superfluid Helium: This is not a chemical reaction, Helium is undergoing physical changes.

2. Thermite and Liquid Nitrogen: This is a chemical reaction. Smoke and fire were produced during this reaction. This is a Metathesis reaction, single replacement reaction. Fe(2)O(3) + 2Al = Al(2)O(3) + 2Fe

1. Briggs-Rauscher Reaction: This is a chemical reaction, because there is a color change. I can’t tell the type of reaction nor the equation because the lack of info needed. 

My favorite would have to be the Potassium Chlorate and Candy Reaction, taking something so sweet, into something… a little more fun.
