Question 1

How many liters of oxygen gas at 153°C and 0.820 atm can be produced by the decomposition of 22.4 g of solid KClO3?  (The other decomposition product is solid potassium chloride.)
◦ 0.085 L
◦ 3.0 L
◦ 4.20 L
◦ 7.79 L
◦ 11.7 L

Question 2

If equal masses of O2(g) and HBr(g) are in separate containers of equal volume and temperature, which one of these statements is true?
◦ The pressure in the O2 container is greater than that in the HBr container.
◦ There are more HBr molecules than O2 molecules.
◦ The average velocity of the O2 molecules is less than that of the HBr molecules.
◦ The average kinetic energy of HBr molecules is greater than that of O2 molecules.
◦ The pressures of both gases are the same.
