Reaction: N 2 (g) + 3 H 2 (g) → 2 NH 3 (g) If you start with a 5 L container of N 2 (at 1 atm pressure) and a 9 L container of H 2 gas (at 3 atm pressure) what is the theoretical yield of NH 3 (g) that can be produced (in moles)? (assume a temperature of 300 K) Example.
At STP, 1 mole of a gas occupies 22.4 lt of volume. Here, we have about 0.45 moles of the gas. Hence the volume occupied by the gas at STP is Thus, the 10 gm of a gas, with a vapor density of 11.2, will occupy 10 lt of volume at STP. Hope this helps. Approved by eNotes Editorial Team.
115. Gasoline (which can be considered to be octane, C8H18) burns in oxygen to produce carbon dioxide and water. What volume of carbon dioxide at STP is generated as a result of the combustion of 1.0 gal of gasoline? (The density of gasoline is 0.81 g/mL. 1 gal = 3.78 L) Chapter 5 Gases Key 1.A 2.E 3.A 4.D 5.B 6.D 7.D 8.C 9.B 10.E
Density: Ratio of the mass of water (kg) occupied in a volume of 1 m3. Specific enthalpy: Sensible Heat, it is the quantity of heat contained in 1 kg of water according to the selected temperature. Specific heat:
One mole of a gas at STP has a volume 22.4 L. So if we have the molar mass of the gas, just divide it by 22.4 to get the density of that gas. molar mass of O2 gas = 32 g/mol.
[1ΔH f (Na2CO3 (s)) + 1ΔH f (H2O (ℓ))] - [2ΔH f (NaOH (s)) + 1ΔH f (CO2 (g))] [1(-1130.94) + 1(-285.83)] - [2(-426.73) + 1(-393.51)] = -169.8 kJ-169.80 kJ ...
Apr 08, 2011 · At an average density, the atmospheric water vapor allows quantum/waves to cross the troposphere to the tropopause in 0.0245 s, i.e. 2.45 cs (centiseconds).By comparing the ability of water vapor to avoid that quantum/waves escape towards the outer space (0.5831 s) with the ability of CO2 (0.0049 s), I can affirm that the role of CO2 on warming the atmosphere or the surface is not possible ...
How much volume does 1 kg of CO2 occupy at room temperature and standard pressure? CO2 has a molecular weight of 44 g/mol 1 kg CO2 = 1000 g × (1 mol/44 g) = 22.7 mol CO2
