Problem: The picture below shows two bulbs connected by a stopcock. The large bulb, with a volume of 6.00 L, contains nitric oxide at a pressure of 0.850 atm, and the small bulb, with a volume of 1.50 L, contains oxygen at a pressure of 2.50 atm. The temperature at the beginning and the end of the experiment is 22°C. After the stopcock is opened, the gases mix and react: 2NO (g) + O2 (g) → 2NO2 (g) Which gases are present at the end of the experiment? What are the partial pressures in atm of the gases? If the gas was consumed completely, put 0 for the answer.

The picture below shows two bulbs connected by a stopcock. The large bulb, with a volume of 6.00 L, contains nitric oxide at a pressure of 0.850 atm, and the small bulb, with a volume of 1.50 L, contains oxygen at a pressure of 2.50 atm. The temperature at the beginning and the end of the experiment is 22°C. After the stopcock is opened, the gases mix and react: 

2NO (g) + O(g) → 2NO(g) 

Which gases are present at the end of the experiment? 

What are the partial pressures in atm of the gases? If the gas was consumed completely, put 0 for the answer.
