Question

Propane reacts with molecular oxygen to produce carbon dioxide and water. How many moles of carbon dioxide are released per home per year?

(a) 1 mole

(b) 2 moles

(c) 3 moles

(d) 4 moles

Answer 1

The balanced equation shows that for every mole of propane burned, 3 moles of carbon dioxide are produced.

Step-by-step explanation:

The balanced equation for the complete combustion of propane is: C3H8 + 5O2 → 3CO2 + 4H2O. From the balanced equation, we can see that for every mole of propane burned, 3 moles of carbon dioxide are produced. Therefore, the correct answer is (c) 3 moles.
