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.
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.
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.
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.
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.

What is the volume hydrogen to oxygen after electrolisis?
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!
How many water vapour can be produced from 10 volume of hydrogen and 5volume of oxygen?
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.
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.
Why does using sodium bicarbonate as electrolyte when performing electrolysis of water produce less than one half volume oxygen for every one volume of hydrogen produced?
Because the electrolysis of water reaction always produces twice as much hydrogen (by volume or by mole) as they do oxygen. H2O(l) -> H2(g) + 1/2 O2(g)
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 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.
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.
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.
