Oxidation Number. For instance, suppose that NG is composed only of CH4 (and mentioned H2S traces) and excess air is 15% during burning, CH4+2O2 --> CO2+2H2O. You have to calculate resulting volume of flue gases, if you want to express produced SO2 in relation to it. SO 2 + 2 H 2 S → 3 S + 2 H 2 O. Sulfur dioxide react with hydrogen sulfide to produce sulfur and water. Double Displacement (Metathesis) Reactants. ChemiDay you always could choose go nuts or keep calm with us or without. Sulfur Dioxide - SO 2. Become a Patron! Reaction Information. The reaction proceeds at room temperature. Thus SO2 would be 600E-6*64=0.0384 kg/kgmol NG =38400/22.4 mg/Nm3 NG = 1714 mg SO2 /Nm3 NG. Sulfur Dioxide + Hydrogen Sulfide = Sulfur + Water. Balance the reaction of SO2 + H2S = S + H2O using this chemical equation balancer! Please register to post comments. Hydrogen Sulfide - H 2 S. Oxidation Number. Reaction Type. SO2 + H2S = S + H2O - Chemical Equation Balancer. Reaction Information. H2S + SO2 = S8 + H2O - Chemical Equation Balancer. In this reaction, ... SO2 + 2 H2S = 3 S + 2 H2O. Add / Edited: 09.10.2014 / Evaluation of information: 5.0 out of 5 / number of votes: 1. 16 H 2 S + 8 SO 2 → 3 S 8 + 16 H 2 O. Balanced Chemical Equation. Reaction Type. Double Displacement (Metathesis) Reactants. Hydrogen Sulfide + Sulfur Dioxide = Octasulfur + Water. Balanced Chemical Equation.
