Q1.

Propane burns to form carbon dioxide and water.

The equation for the reaction is:

C3H8(g) + 5 O2(g) → 3 CO2(g) + 4 H2O(l)

3.60 dm3 carbon dioxide is produced when a sample of propane is burned

in 7.25 dm3 oxygen.

Calculate the volume of unreacted oxygen.

Calculate the volume of unreacted oxygen. Give your answer in cm3- 6182

  1. Ratio of O₂ : CO₂ = 5 : 3
    Volume of CO₂ = 3.80 dm³
    oxygen needed = 3.80×5/3
    =6.0 dm³
    Oxygen given = 7.25 dm³
    Unreacted oxygen = 7.25 − 6.0 = 1.25 dm³
    Convert to cm³:
    1.25 × 1000 = 1250 cm³
