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: 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: Day explained: an extra message for the complainers: chemistry at us on Facebook at on Twitter at the School of Chemistry at The University of Nottingham: Videos films are by video journalist Brady Haran
