Question

Volcanoes emit much hydrogen sulfide gas, H2S, Which reacts with the oxygen in the air to form water and sulfur dioxide, SO2. Every 81 tons of H2S reacts with 114 tons of oxygen and forms 43 tons of water. How many tons of SO2 are formed? ______ tons

Answer 1

2 Reaction in no/eed ZH₂S + 30(85 2802 +2H₂O. Note:- 1 tonos = 106gm. 4 HD S Mase in gm. 81X106 2.4x106 ole мази Moles of O2 = 114 x 106 - 3.568106 - 32 = 5.56x1 Moles of water = 434106 2.4x106 from reaction, of 802 - 2 moles of H₂S reacts with 3 moles of O₂ and Produces &moles 2.4x10€, , 3 x2.4x106, 2 x2048189 molesa S02 Mass of So, produces = No. of Moles x Molar Mass 802 & 2.4x 106 x 64 = 153.6 x 100 gm = 153.6 tonnes & 8
