Cool Reactions

Number 10) Sodium and Chlorine Gas: 2Na +Cl2 —> 2NaCl

This is a chemical reaction because it lit on fire. This also means it was a combustion reaction.

Number 9) 2Mg + CO2 = 2MgO + C. This is a chemical reaction because it is combustion because it has a flame. It is a single replacement chemical reaction. 

Number 8) KClO3+ C6H12O6 —> 6CO2 +4KCl + 6H2O Yes this is a chemical reaction because it is producing something that was not already there. It produced a salt, CO2 and H2O making is a gas producing metathesis reaction.

Number 7) This is not a chemical reaction because the temperature is changing. Therefore there is no chemical equation.

Number 6) This is not a chemical reaction because it is changing states. State change indicates only a physical reaction. It also says the temperature rises, but that also does not mean its a chemical reaction.

Number 5) This is not a chemical reaction either. This reaction is not producing any type of precipitate which means it simply cannot be a chemical reaction.

Number 4) This is not a chemical reaction because it is not reacting with anything or forming anything new. It simply lowers the human voice and that does not make it a chemical reaction.

Number 3) This is not a chemical reaction. This is just describing helium; therefore, nothing is combined with it, and nothing reacts.

Number 2) This reaction is indeed a chemical reaction because it produced smoke and lights on fire. It is a single replacement reaction. Fe2O3 + 2Al –> Al2O3 + 2Fe.

Number 1) This is a chemical reaction because there is a color change, which could really indicate both, but there is also a smell he describes that is produced which positively indicates a chemical reaction. Although this is a chemical reaction I cannot write an equation for it because of the lack of information the video gave.

Personally my favorite was the hexafluoride demonstration. I thought it was neat to see how that reacted just like water would even though its a gas. Also it makes your voice extremely deep which got a few chuckles out of me.

This is another dry ice demonstration that I thought looked cool and was worth sharing.
