Sulfur dioxide reacts with chlorine to produce thionyl chloride (used as a drying agent for inorganic halides) and dichlorine oxide (used as a bleach for wood, pulp, and textiles) . SO₂(g) + 2Cl₂(g) → SOCl₂(g) + Cl₂O(g)
If 0.400 mol of Cl₂reacts with excess SO₂, how many moles of Cl₂O are formed?

Question

Quizplus · Accepted Answer

From the balanced chemical equation, we can see that for every 1 mole of Cl2, 1 mole of SOCl2 is produced. Therefore, if 0.400 mol of Cl2 is used up, we will produce 0.400 mol of SOCl2. However, we also produce 2 moles of ClO2 for every 1 mole of Cl2, so we will produce 0.800 mol of ClO2. Therefore, the answer is 0.200 mol of Cl2O.
