Oxygen is heavier as it has a mass number of 16 whereas hydrogen has a mass number of 1. Both form diatomic molecules (molecules of two atoms) making the formula masses 32 for oxygen and 2 for hydrogen.
When water splits, hydrogen gas and oxygen gas are formed.
Hydrogen gas + Oxygen gas -> Water.
Oxygen gas is considered heavier than other gases (like nitrogen and helium) because the oxygen molecule (O2) has a higher molecular weight due to its two oxygen atoms bonded together. This higher molecular weight causes oxygen gas to be denser and therefore heavier than some other gases.
To extract oxygen from hydrogen peroxide, you can simply heat it. Hydrogen peroxide decomposes into water and oxygen when heated, and the oxygen gas can be collected. This is a common method used in laboratories to obtain oxygen gas.
Oxygen gas is a diatomic molecule composed of two oxygen atoms (O2) that is essential for respiration and combustion. Hydrogen gas is also a diatomic molecule composed of two hydrogen atoms (H2) that is flammable and commonly used as a fuel source.
oxygen gas is heavier than hydrogen gas
Mass of Hydrogen gas:- 2g/mol Mass of Oxygen gas :- 32g/mol Therefore, Oxygen gas is more heavier
Hydrogen gas is H2. Oxygen gas is O2.
Hydrogen is lighter than Oxygen. This is a very simple question. Hydrogen is the first element on the periodic table of elements and it weighs 0.08988 grams per litre. Oxygen is the 8th element on the periodic table. It weighs 1.429 grams per litre. All of the elements (and most chemicals you will ever want to know about) have an article on Wikipedia. These articles almost always include the "weight per amount" known as Density.
When water splits, hydrogen gas and oxygen gas are formed.
Hydrogen peroxide decomposes to hydrogen and oxygen in the gas phase.
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.
When you electrolyze water, it separates into its constituent elements: hydrogen and oxygen gases. This process involves passing an electric current through water, causing the water molecules to break down into hydrogen gas at the cathode and oxygen gas at the anode.
Hydrogen gas + Oxygen gas -> Water.
Hydrogen gas would react with oxgyen and release energy. The lighter hydrogen gas would float to the top of the atmosphere; above the heavier nitrogen and oxygen.
At room temperature: Chlorine: gas Helium: gas Hydrogen: gas Oxygen: gas
Cheese right someone put cheese how is that a colourless gas i will never know but i think the answer is gas
