Question

What volume of oxygen would be required to burn completely 400 ml of acetylene [C₂H₂]? Also calculate the volume of carbon dioxide formed. 2C₂H₂ + 5O₂ 4CO₂ + 2H₂O (l)

KnowledgeBoat · Accepted Answer

[By Gay Lussac's law] 2 Vol. of C₂H₂ requires 5 Vol. of oxygen 400 ml C₂H₂ will require x 400 = 1000 ml of Oxygen Hence, required volume of oxygen = 1000 ml Similarly, 2 Vol. of C₂H₂ produces 4 Vol. of Carbon dioxide 400 ml of C₂H₂ produces x 400 = 800 ml of Carbon dioxide Hence, carbon dioxide produced = 800 ml
