Brrr…Cool Chemical Reactions

Top 10 amazing chemical reactions? We will see which ones are really reactions…

Reaction number 10 is a combination reaction. It uses sodium and chloride to produce a new substance, sodium chloride.

Reaction number 9 is also a chemical reaction. It is a combustion reaction, because the dry ice ignites to produce a flame and reacts with the oxygen in CO2.

Similar to reaction 9, reaction 8 is also a chemical reaction. It is a combustion reaction, because it reacts with oxygen and it produces a flame.

Reaction 7 is NOT a chemical reaction. The only change that occurs is a temperature change, but that is not indicative of a chemical reaction.

Reaction 6 is NOT  a chemical reaction, because it simply changes state, going from saturated in water, to crystalized on a object. It also produces a tempature change, which as I previously stated,  does not demonstrate a chemical reaction.

Reaction 5 is definitely NOT  a chemical reaction. When the absorbent polymers absorb the liquid, they don’t change composition. The two substances did not become something new.

Reaction 4 is NOT a chemical reaction. It uses physical properties to make your voice lower, and does not produce anything new.

Reaction 3 is NOT  a chemical reaction. There is not even another substance that the Helium would be reacting with. Therefore, the helium stays the same, so no  chemical change.

Reaction 2 is a chemical reaction. It burns and produces a thermite reaction.

Reaction 1 is a chemical reaction. There is a color change, which could indicate both a chemical and physical change. There is also change in the aroma, because the substance is originally odorless but leaves smelling like Iodine.

 

Now we can balance the equations of the experiments we know created a chemical reaction ( 10, 9, 8, 2, 1)

10. 2Na + 2Cl = 2NaCl. This is a combination reaction, because we are going from two reactants and making one product.

9. 2Mg + CO2 = 2MgO + C. This is a single replacement because one substance from each side of the equation are switching places.

8. 6KClO3 +C6H12O6 = 6KCl + 6H2O + 6CO2 + 3O2. This is a combustion reaction because it involves hydrocarbons reacting with oxygen.

2. Fe2O3 + 2Al = Al2O3 + 2Fe. This is a single replacement, because two of the reactants are switching.

1. Reaction 1 doesn’t give enough information to write a equation. It simply states that “an colorless solution” reacted. I don’t know about you, but I think that’s pretty vague.

Out of all of these chemical reactions, my favorite is a tie between the Potassium Chlorate and candy reaction (number 8) and the Briggs-Rauscher reaction (number 1). I was very surprised by how much fire and light were caused by the single gummy bear in reaction 8. In reaction 1, I thought it was incredible how the colors in the solution change so suddenly and so completely.
