In the electrolysis of water, it is found that the ratio of volumes of hydrogen and oxygen obtained is 2:1 i.e., 2 volumes of hydrogen and 1 volume of oxygen combines to form water.
How do oxygen and hydrogen compare?
Oxygen contains 8 electrons and eight protons like hydrogen, which has one electron and one proton. Oxygen is accounted for near 21% of the earth atmosphere, and only a negligible amount of hydrogen is present in it. Oxygen is an oxidizing agent, but hydrogen is reducing agent.How did the volume of oxygen gas compare to the volume of hydrogen gas produced by electrolysis Why is there a difference?
Thus, in the Electrolysis Activity, the volume of hydrogen generated is twice the volume of oxygen gas, because the number of hydrogen molecules is twice that of oxygen molecules.What is the volume of oxygen vs hydrogen?
The density of hydrogen at STP is 90 grams per cubic metre. This gives us a volume of 0.2222 cubic metres. The density of oxygen at STP is 1429 grams per cubic metre. This gives us a volume of 0.0112 cubic metres.How did the volume of hydrogen gas collected compare with the volume of oxygen gas collected?
During electrolysis of water the volume of hydrogen collected is twice that of oxygen collected.How does the density of hydrogen and oxygen compare?
The densities of hydrogen and oxygen at STP are 0. 8×10−4g/cc and 12. 8×10−4g/cc respectively. The rms velocity of H2 is v1 and that of O2 is v2 .Why is there 2 times more hydrogen produced than oxygen?
The number of hydrogen molecules produced is thus twice the number of oxygen molecules, in keeping with the facts that both hydrogen and oxygen are diatomic molecules and water molecules contain twice as many hydrogen atoms as oxygen atoms.Which gas has more volume oxygen or hydrogen?
In water (H2O), hydrogen and oxygen are present in the ratio of 2:1 by volume, and thus the volume of hydrogen gas collected is double that of oxygen gas.Why is the volume of h2 produced larger than the volume of O2?
A mole of gas has a volume of 22.4 liters. So even though the hydrogen yield is by weight the far smaller fraction, it is by volume 2/3 of the total simply because there are twice as many atoms of hydrogen as there are of oxygen in every water molecule.Why is oxygen more than hydrogen?
Examples – In water molecules, oxygen is more electronegative than hydrogen. So, oxygen pulls bonded electrons towards itself and gets a slightly negative charge while both hydrogen atoms get a slightly positive charge. The electronegativity value of oxygen is 3.5 while hydrogen is 2.1.Is oxygen 8 times heavier than hydrogen?
Oxygen is 16 times heavier than hydrogen.What is two volumes of hydrogen and one volume of oxygen?
2H2O + O2 ⟶ 2H2O The statement 'two volumes of hydrogen reacts with one volume of oxygen to give two volumes of water'.How does the rate of diffusion of hydrogen gas and oxygen gas compare?
Rate of diffusion of a gas is inversely related to the square root of molar mass of a gas. Therefore, the ratio of diffusion rate of oxygen to hydrogen is $ 1:4 $ .Why is a greater amount of hydrogen gas collected?
Its evident from the equation that water contains two parts of hydrogen and one part oxygen. Therefore, during the electrolysis of water the amount of hydrogen gas collected in one of the test tubes is double than that of the oxygen produced and collected in the other test tube.Is the volume of the gas collected the same in both the test tubes Why?
The amount of gas collected in one of the test tubes in Activity 1.7 is double the amount collected in the other due to the process of Electrolysis. This refers to the electrolysis of water where hydrogen gas in one test tube is double the oxygen produced in the other.Is hydrogen more dense or oxygen?
The answer is Oxygen gas.Gases with higher molar mass are denser. Hence, oxygen would be the densest among the given gases at STP since oxygen has the highest molar mass.
