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.

To determine the volume necessary for hydrogen and oxygen to combine, we need to consider the stoichiometry of the reaction. Hydrogen combines with oxygen in a 2:1 ratio to form water. Therefore, twice the volume of hydrogen is required compared to oxygen. For a 250 ml flask, the volume of hydrogen required would be 166.7 ml, and the volume of oxygen required would be 83.3 ml.

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.
When hydrogen gas and oxygen gas react as much oxygen gas than hydrogen gas is required?
The reaction equation is: 2H2 + O2 = 2H2O So one need two volume part of hydrogen and one volume part of oxygen to form water.
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, it undergoes electrolysis, which breaks water molecules into hydrogen and oxygen gases. The ratio of hydrogen to oxygen gas produced is 2:1, meaning that for every two volumes of hydrogen gas collected, one volume of oxygen gas is collected. Therefore, the volume of gas collected is twice as much for hydrogen compared to oxygen gas.
What evidence in the Hoffman apparatus demonstration indicates the ratio of water's components?
The volume of hydrogen is double the volume of oxygen.
Does a gram of hydrogen or a gram of oxygen have the greater volume at the same temperature and pressure?
They would have the same volume, as long as they are in the same conditions.
How many volumes in hydrogen peroxide?
The volume measure used in hydrogen peroxide refers to the volume of oxygen that it produces
In what volume ratio do hydrogen gas and oxygen gas react to form water?

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!

The reaction equation is: 2H2 + O2 = 2H2O So one need two volume part of hydrogen and one volume part of oxygen to form water.

Why volume of hydrogen should be twice the volume of oxygen formed?
no reason..cause formula for water is h2o
What evidence in the Hoffman apparatus demonstration indicates the ratio of water's components?
The volume of hydrogen is double the volume of oxygen.
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.
Does a gram of hydrogen or a gram of oxygen have the greater volume at the same temperature and pressure?
They would have the same volume, as long as they are in the same conditions.
What volume of hydrogen is necessary to react with five liters of nitrogen to produce ammonia?
10l nh3
What volume of oxygen will remain after reacting 8cm3 of hydrogen with 20cm3 of oxygen?
Where 2H2 + O2 --> 2H2O, you will have 16 cm3 oxygen remaining after the reaction.
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.
