The volume of hydrogen and oxygen after electrolysis:
2H20 (l) + Enegry --> 2H2 (g) + O2 (g)
If electrolysis occurs at standard temp and pressure (s.t.p. = 298.15 K ; 1 atm), then:
PV = nRT
For Hydrogen:
(1 atm) * (Xhydrogen) = 2 moles * (0.08206 L * Atm / K * mol) * (298.15 K)
Xhydrogen = 48.9 L of Hydrogen
since there is half as many moles of Oxygen, then there will be half as much gas or:
Xoxygen = 24.45 L of oxygen (the volume of one mole of gas at s.t.p.)
Remember, this is from 2 moles of water, so if you simplify my balanced chemical equation to one mole of water and a fraction of a mole of oxygen, then you need to decrease the volumes of gasses produced by 0.5. Enjoy!

What do you mean by 100 volume of hydrogen peroxide?
It means that the concentration of the peroxide is such that for every 1mL of hydrogen peroxide solution, 100mL of oxygen will be produced if fully reduced, catalyzed, exposed to light, heated or decomposed in any manner to the fullest extent. The fullest extent means the end point where every molecule of hydrogen peroxide releases one oxygen atom, and is converted into water.
How are volumes of hydrogen peroxide related to concentration of hydrogen peroxide expressed in percentage terms weight volume?
The strength of a solution may be described as a percentage or volume, where 1% hydrogen peroxide releases 3.3 volumes of oxygen during decomposition.Thus, a 3% solution is equivalent to 10 volume and a 6% solution to 20 volume, etc. Answer taken from Wikipedia 19/01/2009
What are elements in acetone?
Carbon, hydrogen, and oxygen
What does 20 volumes hydrogen peroxide mean?
This means that for every volume of hydrogen peroxide used, 20 volumes of oxygen will be produced. For example, if 1 ml of hydrogen peroxide is used/decomposes, 20 ml of oxygen will be formed.
In a chemical formula H2O what does the 2 tell you?
The formula H2O tells you that one molecule of water contains one Oxygen atom and two Hydrogen atoms.
In what volume ratio do hydrogen gas and oxygen gas react to form water?
Approximately twice as much volume of hydrogen as of oxygen: Both gases are diatomic and nearly ideal at normal temperature and pressure, and the atomic ratio of hydrogen to oxygen in water is 2.
Why volume of hydrogen should be twice the volume of oxygen formed?
The volume of hydrogen should be twice the volume of oxygen formed in the electrolysis of water because the ratio of the number of moles of hydrogen to oxygen in water is 2:1. This is based on the molecular formula of water, H2O, where each water molecule contains two hydrogen atoms and one oxygen atom.
What observed when a mixture of oxygen and hydrogen is lit?
Don't try it because if you have 1 volume of oxygen to 2 volumes of hydrogen, it is explosive!
What evidence in the Hoffman apparatus demonstration indicates the ratio of water's components?
In the Hoffman apparatus demonstration, the ratio of hydrogen and oxygen produced indicates the ratio of water's components (H2O). Since water molecule consists of two hydrogen atoms and one oxygen atom, the volume of hydrogen gas produced will be twice that of the oxygen gas when water is electrolyzed.
What is the volume ratio of hydrogen to oxygen in water?
1 mole of water is equal to 18 g.2 g hydrogen is equal to 22,25 L.16 g oxygen is equal to 11,2 L.The volumes ratio H/O is approx. 2.
Why is the volume of gas collected twice of the volume of other gas when electric current is passed through water?
When an electric current is passed through water, water is split into it's two component gasses- hydrogen and oxygen. You will get about twice as much hydrogen as oxygen- since water (H2O) has twice the hydrogen as oxygen.
Does a gram of hydrogen or a gram of oxygen have the greater volume at the same temperature and pressure?
A gram of hydrogen has a greater volume than a gram of oxygen at the same temperature and pressure, as hydrogen has a lower molecular weight and therefore occupies more space per gram compared to oxygen.
When hydrogen gas and oxygen gas react as much oxygen gas than hydrogen gas is required?
The reaction between hydrogen gas and oxygen gas forms water, with 2 moles of hydrogen gas reacting with 1 mole of oxygen gas. This means that twice as much hydrogen gas is required compared to oxygen gas for the reaction to occur completely.
What volume of oxygen will remain after reacting 8cm3 of hydrogen with 20cm3 of oxygen?
To determine the volume of oxygen remaining after the reaction, we first need to determine the stoichiometry of the reaction. The balanced chemical equation for the reaction of hydrogen and oxygen is 2H2 + O2 -> 2H2O, meaning 2 volumes of hydrogen react with 1 volume of oxygen to produce 2 volumes of water vapor. Since the reaction ratio is 2:1 for hydrogen to oxygen, the 8cm3 of hydrogen will react with 4cm3 of oxygen. Therefore, the initial 20cm3 of oxygen minus the 4cm3 used in the reaction leaves 16cm3 of oxygen remaining.
Volume of gas are not equal during electrolysis of water?
During electrolysis of water, the volume of gas produced at the anode (oxygen) is twice that of the volume of gas produced at the cathode (hydrogen). This is because water molecules (H2O) split into two hydrogen atoms for every one oxygen atom when an electric current is passed through the water during electrolysis.
If a bottle of hydrogen peroxide is labeled 10 volts what does this indicates?
Volume is the amount of oxygen that is contained in a given amount of peroxide. For example, 3% hydrogen peroxide is V10 or 10 volume, because it will release 10 times it's volume in oxygen. One pint of 3% hydrogen peroxide will release 10 pints of oxygen as it breaks down. Gee, now there is something to think about. Of course, V20 will release twice as much oxygen, 20 times its volume.
What volume is necessary for hydrogen and oxygen to combine in a 250 ml flask?
The stoichiometric volume ratio for complete combination is approximately 2:1 (it's not PRECISELY 2:1 because neither hydrogen nor oxygen is an ideal gas), so if you want them to combine as completely as possible, 2/3 of that 250 ml should be hydrogen and 1/3 should be oxygen.You'd do better measuring masses (in which case you want the ratio to be 2.016 parts hydrogen to 15.9994 parts oxygen), but that's a lot harder to do, and going by volume is definitely close enough to give one heck of a bang when you set it off. I saw this done once, using an ordinary party balloon and a candle on the end of a very long stick in a large auditorium, and it literally shook the entire building when it went off.
