In this video, this man puts a ball of aluminium inside a bottle; then adds hydrochloric acid, and closes the bottle. Then after around the 30 seconds the bottle explodes and white smoke fills the room. The balanced equation for this reaction is 2 Al + 6 HCL ---> 2 AlCl3 + 3 H2 and it's a single replacement reaction. I know a chemical reaction occurred because heat and flame was produced, since it exploded.
The balanced chemical formula for this is cyalume + H2O2 -----> trichlorophenol + 2CO2+ dye. This is a combustion reaction. A chemical reaction occurred because light was produced.
