Cool Chemical Reactions

In this blog, I will be discussing the reactions from this list of the “Top 10 Amazing Chemical Reactions” http://listverse.com/2008/03/04/top-10-amazing-chemical-reactions/. First, I will determine whether each reaction is an actual chemical reaction, and if so, what type of reaction and the balanced equation formula for each. Then, I will describe my favorite reaction and why I like it more than the others.

10. Sodium and Water in Chlorine Gas: This is an actual chemical reaction because a gas and a salt are produced. It is a synthesis reaction. The balanced chemical equation for this reaction is 2Na+Cl2= 2NaCl.                       .

9. Magnesium and Dry Ice Reaction: This is a chemical reaction because the magnesium burns in nitrogen and carbon dioxide, and obviously a gas is produced. It is a single replacement metathesis reaction with a balanced equation of 2Mg+CO2= 2MgO+C.

8. Potassium Chlorate and Candy Reaction: This is a chemical reaction because oxygen gas is produced as a result of something burning. This is a combustion reaction for the reason that it is a burning reaction with oxygen. The balanced chemical equation for this reaction is 6KClO3 + C6H12O6 –> 6KCl + 6H2O + 6CO2 + 3O2.

7. Meissner Effect: This is not a chemical reaction because the temperature changes, but no new substances are created or destroyed.

6. Sodium Acetate Super Saturation: This is not a chemical reaction because although the heat is produced, it is simply a phase change, not a chemical change.

5. Superabsorbent Polymer: This is not a chemical reaction because the polymer just absorbs liquid, but it doesn’t change chemically in doing so.

4. Floating on Sulfur Hexafluoride: This is not a chemical reaction because the sulfur hexafluoride has the ability to “lift” things because it is denser than air, but no chemical change occurs.

3. Superfluid Helium: This is not a chemical reaction because as the helium cools, it undergoes a physical change, not a chemical change.

2. Thermite and Liquid Nitrogen: This is a chemical reaction because smoke and fire is produced. It is an example of a single replacement reaction, under the category of redox reactions, and the balanced equation is as follows: Fe2O3 + 2Al –> Al2O3 + 2Fe.

1. Briggs-Rauscher Reaction: This is a chemical reaction because there is a repeat change in color, indicating chemical change. From the information given, it is impossible to determine the type of chemical reaction or the corresponding balanced equation.

 

 

 

 

My favorite chemical reaction was Number 8, the Potassium Chlorate and Candy Reaction. I thought it was very interesting and a bright, obvious chemical reaction, making it stand out from the others. It was quite fun to watch.
