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.
