For this post, we’ll be looking at the “Top Ten Chemical Reactions” from Listverse.com. Now, for those of you who do not know, not all of these are actually chemical reactions, and I’m here to explain why.
The explanations of each reaction will be listed by the number the reaction appears as on the list.
10. This is a chemical reaction. Simply put, the reaction clearly produces gas, which is a huge indicator of a chemical reaction. The reaction produces something new, thus indicating a chemical reaction.
9. This is an obvious chemical reaction, as the magnesium is burning, a sure sign of chemical change.
8. Once again,we see here another chemical reaction. This is indicated by,you guessed it, burning and gas production.
7. This reaction is not a chemical reaction. There is no sure indicator, as temperature change occurs in both physical and chemical changes.
6. Yet again, we see here a reaction that’s” not-so-chemical.” The reason being is that A PHYSICAL CHANGE IS NOT A CHEMICAL CHANGE. This cannot be stressed enough. Through the reaction, sodium acetate remains sodium acetate in multiple forms. Something different is not produced,and therefore there is no chemical reaction.
5. Another mistake by the website, this reaction is not chemical. Obviously so, the hydrogels remain hydrogels, and the water remains water. There is no product, and no chemical change.
4. This “reaction” is pretty obvious, considering that Sulfur Hexafloride ISN’T REACTING WITH ANYTHING…. a single chemical by itself is NOT a chemical change. It is still Sulfur Hexafloride after its “reaction,” and is not in any way a chemical reaction.
3. Superfluid Helium, although cool,is not a chemical change. Reflecting back we must remember, a physical change is not a chemical change.
2. Smoke + Fire = well, a chemical reaction. In this reaction, we see the thermite’s component chemicals reacting with the liquid nitrogen, giving us our chemical reaction.
1. This reaction is chemical, and possibly a little hard to identify. Color change, often an indicator of chemical change, is the only indicator present, making it a little tough to identify. This reaction, however, is indeed chemical.
Next, we need to get out some balanced chemical equations for those reactions that were identified as chemical.
10. 2Na + Cl2 —-> 2NaCl ; This equation is a synthesis and redox reaction.
9. 2Mg + CO2 —-> 2MgO + C ; This is known as single replacement metathesis.
8. 6KClO3 + C6H12O6 —-> 6KCl + 6H2O + 6CO2 + 3O2 ; This reaction is most likely combustion, giving the reacting that occurs in experimentation and its products in the equation.
2. This equation was the best I could find, giving the variable forms of thermite. This equation uses ferric oxide and aluminum powder. Fe2O3 + 2Al —-> Al2O3 + 2Fe ; In this case, the reaction is a single replacement metathesis and redox reaction.
1. This reaction’s equation, unfortunately, was almost unidentifiable based on the chemicals and reactions. I was unable to determine this equation.
My favorite reaction probably had to be #8- The Potassium Chlorate & Red Gummy Bear reaction. Just the sheer chaos that ensues when the bear hits the chemical is, well, awesome. It also shows how chemical compositions affect reactions, because honestly, who would suspect a gummy beat could cause a reaction like that?
