Reaction video #1
Reaction of Magnesium and Oxygen
Magnesium and Oxygen. Synthesis
2Mg(s) + O2(g) YIELDS 2MgO(s)
By the way, I had this video before you showed us it.
Reaction video #2
Combustion of trimethyl borate
Trimethyl borate. Combustion
2CH3OH +3O2 YIELDS 2CO2 + 4H2OThe green color of the flame due to the combustion of boron compounds is demonstrated burning the mixture.
Reaction video #3
Cool Chemical Volcano
Ammonium Dichromate. Decomposition
(NH4)2Cr2O7 (s) → Cr2O3 (s) + N2 (g) + 4 H2O
It looks more like a volcano after some time has passed. Also the website given at the end also has some other interesting cool chemical reactions videos
