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 is the molar ratio of hydrogen to oxygen?
The molar ratio of hydrogen to oxygen in water (H2O) is 2:1. This means that for every 2 moles of hydrogen, there is 1 mole of oxygen.
What is the ratio of oxygen atoms to hydrogen atoms in a water molecule?
2 hydrogen, 1 oxygen. The equation for water is H2O, meaning 2 parts hydrogen and 1 oxygen. Oxygen is a bigger element than hydrogen, hydrogen being the least dense substance on earth (which is why it rises in air) External links to a picture of a magnified water molecule:
Best Hydrogen gas to Oxygen gas ratio for combustion to occur?
The reaction is 2H2 + O2-> 2H2O So, both the molar and volume ratios would be 2 moles(liters) of hydrogen to every mole(liter) of oxygen. By weight, the ratio would be about 8 grams of oxygen to every gram of hydrogen
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.
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.
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 characteristic do carbohydrates have concerning their hydrogen and oxygen atoms?
The hydrogen- oxygen ratio is 2:1, which is the same ratio in 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, 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.
When combined in a ratio with hydrogen the element makes water?
Oxygen. Hydrogen and oxygen bond in a ratio of 2 hydrogen atoms to one oxygen atom to form water, represented by the chemical formula H2O.
What is the molar ratio of hydrogen to oxygen?
The molar ratio of hydrogen to oxygen in water (H2O) is 2:1. This means that for every 2 moles of hydrogen, there is 1 mole of oxygen.
What is the ratio of hydrogen to oxygen in this sample of four water molecules?
2:1 ratio. There would be eight atoms of hydrogen and four atoms of oxygen.
What is the ratio in the organic compound for water?
Water is an inorganic compound.
Hydrogen and Oxygen present in a 1 to 2 to 1 ratio is what?
Hydrogen and oxygen present in a 1:2:1 ratio is characteristic of water (H2O). This ratio reflects the stoichiometry of water where each water molecule contains two hydrogen atoms for every one oxygen atom.
The molecule of water is a combination of?
The molecule of water is of hydrogen and oxygen in the ratio-1;2.
What is the ratio of oxygen atoms to hydrogen atoms in a water molecule?
2 hydrogen, 1 oxygen. The equation for water is H2O, meaning 2 parts hydrogen and 1 oxygen. Oxygen is a bigger element than hydrogen, hydrogen being the least dense substance on earth (which is why it rises in air) External links to a picture of a magnified water molecule:
