Dichromate Volcano 2.1
(NH4)2Cr2O7 → N2 + 4 H2O + Cr2O3
Thermal decomposition of ammonium dichromate (VII)
The use of dichromate compounds has been banned in schools in many countries around the world, fortunately I had the chance to carry out and record this practical in a fume cupboard prior to the ban. Please do not attempt this practical without supervision and appropriate safety measures.

Wow
Really Amazing 😍😍😍😍😍😍😍
Amazing
It is really funny to see my previous physics teacher making UA-cam videos. Good to see he still has fun. :)
The only thing better than blowing stuff up is recording yourself blowing stuff up 😄
loser u suck and i hate ur science lessons boringg
LLESSSGOOOO MR SHEPLEEYYYY
Hey! how's it going?
Nice
I subscribed sir, cool channel.
Much appreciated!
awesome
woah
How can I donate ???
😂😂😂😂😂
Best Teacher
Our chemistry teacher is so cool
very cool
wait, are you in the UAE?
Very close, that was in Qatar
@@yopaque the weather and the housing design is similar to ours (UAE)
@@TopG20073 Starting to get a bit too hot to do practicals outside! 😄
