Not a combustion reaction. Combustion reactions produce CO2 and H2O.
Br2 + 3NaHSO3 = 2NaBr + NaHSO4 + H2O + 2SO2
SO2 + H20 --> H2SO3 sulphurous acid is not very stable though # The forest school, the forest school is wonderful the forest school is wonderful its filled with beer and Viagra the forest school is wonderful!!! #
Pyrite (fools gold) reacts with Oxygen to make Hematite (Fe2O3) and Sulpher dioxide (SO2) The reaction is oxidation of pyrite. 2FeS2 + 3.5O2 - - Fe2O3 + 2SO2

adding SO2
Br2 + 3NaHSO3 = 2NaBr + NaHSO4 + H2O + 2SO2
2ZnS + 3O2 ---> 2ZnO + 2SO2 Zinc sulphide + Oxygen ---> Zinc oxide + Sulphur dioxide This reaction is endothermic and requires a heat change (H) in order to happen. As the Zinc sulphide reacts with the oxygen the zinc becomes oxidised (oxidation, zinc atoms bond to oxygen atoms), and during this reaction sulphur dioxide is given off.
keq=[SO3]2[O2] [So3]2
2SO2(g) + O2(g) 2SO3(g)-The reverse reaction is favored.
Increase the concentration of SO2
K2CO3 s -> K2O s plus CO2 g 2SO3 g -> 2SO2 g plus O2 g
2PbS+3O2 goes to 2SO2+ 2PbO
2CuSO4 = 2CuO + 2SO2 +O2the reaction only takes place when heated .
