APFIVE Precipitation and Gas Pressure Calculation
When 25.0 mL of 0.200 M AgNO₃(aq) is combined with 15.0 mL of 0.150 M CaCl₂(aq), a precipitate is formed. The precipitate is then heated to 500 K in a 2.00 L container, causing it to decompose completely according to the equation: 2AgCl(s) → 2Ag(s) + Cl₂(g). What is the partial pressure, in atm, of O₂(g) in the container?
A
0.0462 atm
B
0.0000 atm
C
0.0308 atm
D
0.0154 atm
