no reason..cause formula for water is h2o
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.
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.
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.
Hydrogen peroxide is a liquid compound and does not have volumes in the same way that gases or solids do. It is typically sold and measured by its concentration in percentages, such as 3% or 6% hydrogen peroxide.
The reaction between hydrogen and oxygen to form water is given by the equation: 2H2 + O2 -> 2H2O. This means that 2 volumes of hydrogen react with 1 volume of oxygen to produce 2 volumes of water vapor. Therefore, from 10 volumes of hydrogen and 5 volumes of oxygen, 10 volumes of water vapor can be produced.
The volume of hydrogen gas compares to the volume of oxygen gas based on their stoichiometric ratio in chemical reactions, particularly in the formation of water. In the reaction 2H₂ + O₂ → 2H₂O, two volumes of hydrogen gas react with one volume of oxygen gas. This means that for every two volumes of hydrogen, there is one volume of oxygen. Therefore, the volume of hydrogen gas is twice that of oxygen gas in this specific reaction.
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.
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.
Don't try it because if you have 1 volume of oxygen to 2 volumes of hydrogen, it is explosive!
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.
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.
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.
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.
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.
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.
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.
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.
