Chemistry

Consider the combustion of butane:

C4H10(g) +O2(g)->CO2(g)+H2O(l) (unbalanced)

Let 2.00 g of butane gas and 3.05 atm of oxygen gas completelyreact (limiting) in a 2.00-L container at 125C.

2.1 Will there be a net increase or decrease in total pressureafter the reaction is complete?

2.2 After complete reaction, what will be the mole fraction ofH2O gas in the system?
