Question

1. The combustion of octane, C8H18, proceeds according to the reaction shown. 2C8H18(l) + 25O2(g) ⟶ 16CO2(g) + 18H2O(l) If 434 mol of octane combusts, what volume of carbon dioxide is produced at 25.0 °C and 0.995 atm? 2. Chlorine can be prepared in the laboratory by the reaction of manganese dioxide with hydrochloric acid, HCl(aq), as described by the chemical equation MnO2(s) + 4HCl(aq) ⟶ MnCl2(aq) + 2H2O(l) + Cl2(g) How much MnO2(s) should be added to excess HCl(aq) to obtain 355 mL Cl2(g) at 25 °C and 805 Torr? 3. A 1.05 g sample of an unknown gas at 35 °C and 1.05 atm is stored in a 1.65 L flask. What is the density of the gas? What is the molar mass of the gas?

Description: 1 the combustion of octane c8h18 proceeds according to the reaction shown 2c8h18l25o2g16co2g18h2ol if 434 mol of octane combusts what volume of carbon dioxide is produced at 250 c and 0995 a 04776

          1. The combustion of octane, C8H18, proceeds according to the reaction shown.
2C8H18(l) + 25O2(g) ⟶ 16CO2(g) + 18H2O(l) 
If 434 mol of octane combusts, what volume of carbon dioxide is produced at 25.0 °C and 0.995 atm?

2. Chlorine can be prepared in the laboratory by the reaction of manganese dioxide with hydrochloric acid, HCl(aq), as described by the chemical equation
MnO2(s) + 4HCl(aq) ⟶ MnCl2(aq) + 2H2O(l) + Cl2(g)
How much MnO2(s) should be added to excess HCl(aq) to obtain 355 mL Cl2(g) at 25 °C and 805 Torr?

3. A 1.05 g sample of an unknown gas at 35 °C and 1.05 atm is stored in a 1.65 L flask.
What is the density of the gas?
What is the molar mass of the gas?
