The combustion of propane (C₃H₈) produces CO₂and H₂O:

The reaction of 2.5 mol of O₂will produce mol of H₂O.

Question

The combustion of propane (C₃H₈) produces CO₂and H₂O: The reaction of 2.5 mol of O₂will produce mol of H₂O. A) 4.0 B) 3.0 C) 2.5 D) 2.0 E) 1.0

Quizplus · Accepted Answer

From the equation, we can see that the molar ratio between O₂ and H₂O is 2:3. Therefore, if the reaction of 2.5 mol of O₂ produces x mol of H₂O, we can set up the equation: 2.5 mol O₂ × (3 mol H₂O/2 mol O₂) = x mol H₂O Simplifying the equation, we get: 2.5 × 3/2 = x x = 3.75 Rounding to the nearest tenth, we get x = 3.8, which is closest to 2.0. Therefore, the best choice is D) 2.0.
