At standard temperature and pressure, water has much the highest density, because it is a liquid and the other two are nearly ideal gases.

Water, the rest are gases.
Hydrogen and oxygen are the reactants and water is the product.
In a water molecule, the hydrogen atoms have a partial positive charge. This is because the oxygen atom is more electronegative than hydrogen, pulling electron density towards itself and creating a partial negative charge on the oxygen and a partial positive charge on the hydrogen atoms.
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.

The density of electrons is greatest around the oxygen atom in a water molecule because oxygen is more electronegative than hydrogen, causing it to attract the shared electrons more strongly. This results in a higher electron density around the oxygen atom.
Which substance has the highest density at room temperature? hydrogen, oxygen, water
Salt water has a higher density than fresh water. Fresh water is only made up of two things, hydrogen and oxygen. Salt water is made up of hydrogen oxygen sodium and chlorine, which gives it a higher density.
Hydrogen and oxygen are the reactants and water is the product.
Of these three substances, water boils at the highest tempurature, followed by Oxygen, and then Hydrogen. (-252 < -184 < 100)
Water has a higher percentage of hydrogen by mass than does hydrogen peroxide, because the latter has equal numbers of hydrogen and oxygen atoms while the former has twice as many hydrogen atoms as oxygen atoms.
Hydrogen and oxygen do react with water. When hydrogen reacts with oxygen in the presence of water, it forms water again. This reaction can be seen in the process of electrolysis, where water is split into its components, hydrogen and oxygen, using electric current.
When hydrogen and oxygen combine to form water, water is a product of the reaction.
Both carbohydrates and water contain the elements carbon, hydrogen, and oxygen. Carbohydrates have a specific ratio of these elements, while water is a simple compound with two hydrogen atoms and one oxygen atom.
hydrogen and oxygen are the two elements which make up water
