XeF4 is a gaseous compound that only contains fluorine and xenon. A 100.0 mL steel vessel filled with 0.283 g of XeF4 has a pressure of 0.178 atm at 0 °C. XeF4 breaks down into its component parts when the vessel is heated up to 117 °C. What are the partial pressures of xenon and fluorine in the container, as well as the total pressure?
The density of a group 2A metal is 1.55 g/cm3 and crystallizes in a cubic unit cell that has an edge length of 653 pm. When a 1.65 cm3 slab of this metal reacts with excess hydrobromic acid, the gas produced occupies a volume of 1.50 L with a pressure of 794 mmHg at 27.0°C. What is the identity of the metal?
A 1.50 L reaction flask contains 14.22% O2, 61.27% CO2, and 24.51% water vapor at 30.0°C. The total pressure inside the flask is 24.61 kPa. Calculate the mass of naphthalene (C10H8) that was burned in order to produce this amount of water vapor.
C10H8(s) + 12 O2(g) → 10 CO2(g) + 4 H2O(g)
Consider the following reaction:
Cl2(g) + F2(g) → ClF3(g) [unbalanced]
At 301 K, a 2.50-L reaction chamber is initially composed of chlorine gas and fluorine gas with a partial pressure of 472 mmHg and 862 mmHg, respectively. Determine the limiting reagent. What is the theoretical yield of ClF3?
Consider the following reaction:
2 SO2(g) + O2(g) → 2 SO3(g)
At 345 K and 75.0 mmHg, 265.3 mL of SO3 were collected when 305.2 mL of SO2 and 176.4 mL of O2 reacted. What is the percent yield of the reaction?
The following reaction produces 2.50 g of solid potassium chloride. Calculate the total volume of oxygen gas that can be collected over water at 25.0 °C and 760 mmHg. Note that the vapor pressure of water at 25.0 °C is 3.169 kPa.
2 KClO3 (s) → 2 KCl (s) + 3 O2 (g)
The hydrogen gas produced from a chemical reaction was collected over water at 40°C with a total pressure of 715 mmHg. (Water pressure is 55.3 mmHg at 40°C.)
a. What would be the partial pressure of the hydrogen gas collected?
b. What is the mass of hydrogen gas collected if the total volume of gas collected is 763 mL?
