Propane is a bigger hydrocarbon: 3 carbons single-bonded in a chain, and the remaining bonds are taken by hydrogen. Its formula is C3H8 and its structure is shown below. KEY POINT: the products are the same as the combustion of methane, but more is produced.

Some of the liquid water evaporates into the gas, and increases the total pressure generated by the trapped gas. As the H2(g) is bubbled up the reaction solution, some of the H2(g) molecules are solubilized by water in the aqueous solution, effectively decreasing the measured pressure above. The pressure contributed by the H2(g) is greater than the measured total pressure because of the contribution of partial pressure of water vapor. The pressure exerted by the evolved H2(g) is reduced because of the co-presence of water vapor, thus Pwater vapor has to be added to Pdry gas.
