Initially 4.00 L NO at 0.500 atm and 2.00 L O2 at 1.00 atm are in different bulbs separated by a valve. After the valve is opened and the reaction is complete, what is the partial pressure of NO2? 2NO(g) + O2(g) → 2NO2(g)   0.333 atm   0.222 atm   0.166 atm

The Haber Process synthesizes ammonia at elevated temperatures and pressures. Suppose you combine 1580 L of nitrogen gas and 4240 L of hydrogen gas at STP, heat the mixture to run the reaction, then separate the ammonia from the reaction mixture. What volume of reactant, measured at STP, is left over? Assume the reaction goes to completion. N₂ (g) + 3 H₂ (g) → 2 NH₃ (g)

8) Consider the apparatus pictured below, which consists of two containers separated by a valve. CH;N(g) 285 mL O2(g) 419 mL 591 torr 1766 torr The valve is opened and the gases react as follows (note that the temperature is high enough that the water is produced as a gas): 4 C2H;N(g) + 15 O2(g) → 8 CO2(g) + 14 H2O(g) + 2 N2(g) What will be the total pressure in the apparatus when the reaction has gone to completion? Assume that the temperature does not change.

When the following reaction takes place inside a balloon, what will happen to the volume of the balloon as the reaction proceeds? Assume the pressure and temperature remain constant. Cl₂ (g) + H₂(g) → 2 HCI (g) The balloon gets smaller The balloon gets larger The balloon stays the same size
