Barking Dog Chemical Reaction (reaction only)

Barking Dog chemical reaction - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: Gold, Sulfur, Vanadium and Cerium (fe...
NOTE 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.
