When CO2(g) and H2O(g) react, the two gaseous products are collected in separate containers. If 5.00 g CO2 reacts with an excess of H2O, what volume of O2 will be produced at STP (standard temperature and pressure), given that the ideal gas constant, R, is equal to ?

Use the following information to answer questions:

The reaction of gaseous carbon dioxide and steam results in the formation of oxygen gas and acetylene gas. A balanced equation for this reaction is shown below:

CO2(g) + 2H2O(g) → 2C2H2(g) + 5O2(g)

ΔH values are provided for a series of related reactions:
C2H2(g) + 2H2(g) → C2H6(g) ∆H = –94.5 kJ
H2O(g) → H2(g) + 1/2O2(g) ∆H = –71.2 kJ
C2H6(g) + 7/2O2(g) → 2CO2(g) + 3H2O(g) ∆H = –283 kJ
