The following apparatus shows three enclosed 0.500 L bulbs connected by stopcocks. Bulb X at 200°C has a total pressure of 650 mmHg and contains Br2(g), I2(g), and Cl2(g). Bulb Y and Bulb Z are both empty and held at a temperature of 95.0°C and 25.0°C, respectively. Initially, the stopcocks are closed. Assume that the volume of the lines joining the bulbs is negligible.

When the stopcock between X and Y opened and the mixture was allowed to reach equilibrium, X and Y had a total pressure of 270 mmHg. What is contained in bulbs X and Y?
