Barking Dog Chemical Reaction

Barking Dog chemical reaction - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=vsiPt3l6H3UNOTE FROM THE PROFESSOR: 4. The basic mixture is carbon disulfide CS2 plus nitrous oxide, N2O. The N2O decomposes and 2N2O → 2N2 + O2. This reaction needs heat to get it going but is then quite violent. The O2 Reacts with CS2 to make a mixture of CO2, SO2 and solid sulfur. Some of the sulfur and SO2 are formed in a so-called excited state (with a big excess of energy) and the energy is lost by emission of blue light.See our 24 reactions playlist as it unfolds at: http://www.youtube.com/playlist?list=PL6E4F35510525FFF7Berzelius Day explained: http://www.youtube.com/watch?v=wDXUDq2KLM4And an extra message for the complainers: http://periodicvideos.blogspot.co.uk/2012/08/berzeliusday.htmlMore chemistry at http://www.periodicvideos.com/Follow us on Facebook at http://www.facebook.com/periodicvideosAnd on Twitter at http://twitter.com/periodicvideosFrom the School of Chemistry at The University of Nottingham: http://www.nottingham.ac.uk/chemistry/index.aspxPeriodic Videos films are by video journalist Brady Haranhttp://www.bradyharan.com/
