What mass of O2 is required to react with H2 to produce 4.19 L of H2O(g) at 172°C and 0.801 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)

Roasting galena [lead(II) sulfide] is an early step in the industrial isolation of lead. How many liters of sulfur dioxide, measured at STP, are produced by the reaction of 6.45 kg of galena with 145. L of oxygen gas at 220 °C and 2.00 atm? Lead(II) oxide also forms. Be sure your answer has the correct number of significant figures. Note: Reference the Fundamental constants table for additional information. L SO₂ x10 X

Oxygen gas can be obtained by the thermal decomposition of mercuric oxide;2 HgO(s) + heat → 2 Hg(l) + O 2(g)How many grams of HgO must be decomposed to produce 0.6433 L, measured at 9.426 °C and 1.081 atm?

What would be the pressure of H2 (g) formed by the reaction of 89 grams of Al performed in a 10L flask at 85 degrees celsius?

What volume in liters of fluorine gas is needed to form 863 L of sulfur hexafluoride gas if the following reaction takes place at 2.00 atm and 273.15 K: S(s) + 3F₂(g) → SF₆ (g)?

In an experiment, 175 mL of nitrogen gas was collected over water at 23.5 oC and 757 mmHg. What mass of nitrogen gas was obtained? At the temperature of the gas (23.5 oC), the vapor pressure of water is 21.8 mmHg.
