I believe it's gonna be B or C
C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O + heat
Explanation:
When Sean cook meals with propane he use a combustion reaction:
C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O + heat

Hello there!
In this case, according to the given data, it is possible to infer that the gas mixture lies on the 15.0 cm-high column of water, so that the total pressure or atmospheric pressure is given by:

Thus, since the atmospheric pressure is 745 mmHg and the vapor pressure of water is 18 mmHg, the pressure of hydrogen turns out to be:
