What is the total volume of hydrogen gas and oxygen gas that can be produced from the thermal decomposition?
The volume of a mole of gas at standard temperature and pressure is 22.4 liters. So the amount of H2 will be 22.4 L and the volume of O2 will be 1/2 x 22.4 = 11.2 L.
What is the volume of hydrogen and oxygen?
The ratio of the volumes of hydrogen and oxygen obtained on electrolysis of water is 2:1. This is because, one molecule of water contains two hydrogen atoms and one oxygen atom in it. The volume of hydrogen and oxygen obtained on electrolysis of water is in the ratio ___.
How many grams of hydrogen and oxygen are produced when 9 grams of water is decomposed?
Thus, if 9 g of water is decomposed, 1 g of hydrogen and 8 g of oxygen are always obtained.
What is the volume of hydrogen?
Specific volume is the inverse of density and expresses the amount of volume per unit mass. Thus, the specific volume of hydrogen gas is 191.3 ft3/lb (11.9 m3/kg) at 68 ºF (20 ºC) and 1 atm, and the specific volume of liquid hydrogen is 0.226 ft3/lb (0.014 m3/kg) at –423 ºF (–253 ºC) and 1 atm.
How do you find the ratio of hydrogen and oxygen?
The atomic mass of Hydrogen is 1 u. The atomic mass of oxygen is 16u. Since, there are 2 atoms of hydrogen and 1 atom of oxygen in a water molecule, the ratio of their masses is 2:16 or 1:8.
How much oxygen is in 9 grams of water?
9g=6.0222×1023 molecules of H2O=3.011×1023 molecules of H2O.
What is the mass of 0.5 mole of hydrogen atom?
therefore 0.5 mole = 1/2 grams = 0.5 grams.
How do you find the volume of hydrogen gas?
- Step 1 – Calculate the amount of sodium. Amount in mol = Amount in mol =
- Step 2 – Find the amount of hydrogen. From the balanced equation , the mole ratio Na:H 2 is 2:1. Therefore 0.20 mol of Na produces = 0.10 mol of H 2
- Step 3 – Calculate the volume of hydrogen. Volume = amount in mol × molar volume. Volume = 0.10 × 24.
What is the volume of oxygen?
Oxygen – Weight and Volume Equivalents
| Weight of Liquid or Gas | Volume of Gas at 70°F (21°C) and 1 atm | |
|---|---|---|
| lb | kg | m3 |
| 2.205 | 1.000 | 0.754 |
| 2.516 | 1.141 | 0.861 |
| 9.524 | 4.320 | 3.258 |
How much CO2 is produced from one ton of hydrogen gas?
Depending on the quality of the feedstock (natural gas, rich gases, naphtha, etc.), one ton of hydrogen produced will also produce 9 to 12 tons of CO 2, a greenhouse gas that may be captured. For this process high temperature (700–1100 °C) steam (H 2 O) reacts with methane (CH 4) in an endothermic reaction to yield syngas.
What is the volume of air needed to supply pure oxygen gas?
By the way, that’s 17.5 L of pure oxygen gas. If, perchance, you were asked to determine the total volume of atmospheric air needed to supply 17.5 L of pure oxygen gas at STP, the calculation would be 17.5 / 0.20 = 87.5 L. This is because oxygen gas is approximately 20\% of the atmosphere.
What is the main source of hydrogen in the atmosphere?
Fossil fuels are the dominant source of industrial hydrogen. Carbon dioxide can be separated from natural gas with a 70–85\% efficiency for hydrogen production and from other hydrocarbons to varying degrees of efficiency. Specifically, bulk hydrogen is usually produced by the steam reforming of methane or natural gas.
What are the methods of making hydrogen from natural gas?
1 Methane pyrolysis. Pyrolysis of methane is a hydrogen production process from natural gas. 2 Partial oxidation. Hydrogen production from natural gas or other hydrocarbons is achieved by partial oxidation. 3 Plasma reforming. 4 From coal. 5 From petroleum coke.
