Three bulbs are connected by tubing, and the tubing is evacuated. The volume of the tubing is 34.0 mL. The first bulb has a volume of 52.0 mL and contains 3.97 atm of argon, the second bulb has a volume of 250 mL and contains 1.14 atm of neon, and the third bulb has a volume of 42.0 mL and contains 8.44 atm of hydrogen. If the stopcocks (valves) that isolate all three bulbs are opened, what is the final pressure of the whole system in atm?

HCl(g) can be made by the direct reaction of H2 and Cl2 in the presence of light. 6.00 g of H2 and 1.50 x 102 g Cl2 are mixed in a 5.00 L flask at 28.0 °C. What are the partial pressures of gases after the reaction has completed. Given Information:             > Temperature and volume remains constant at 28.0 °C             > Wavelength of light needed for the reaction is 340 nm.

How many moles of hydrogen chloride are required to produce 12.0 liters of chlorine, measured at 1.22 atm and 19°C? 4 HCl + O 2 → 2 Cl 2 + 2 H 2O is the balanced equation for this process.

What volume of hydrogen gas will be produced when 5.00 g of calcium reacts with excess hydrochloric acid at STP? (STP is standard temperature and pressure. Standard temperature is 0oC and standard pressure is 1.00 atmospheres.) What is the name of this law?

Aluminum, an active metal, reacts with hydrochloric acid in a single displacement reaction.  a) Write the equation for the reaction. b) If I drop a 1.00 gram piece of aluminum metal into 200. mL of 0.405M hydrochloric acid solution, will the aluminum react completely?  c) What volume will the product gas occupy at 35°C and 945 torr pressure?
