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)

The ratio of the number of hydrogen atoms to the number of oxygen atoms in any physical state of water is always 2:1, as shown by the chemical formula of water, H2O.
The ratio of hydrogen to oxygen atoms in a water molecule is 2:1, with two hydrogen atoms for every one oxygen atom.
The hydrogen to oxygen ratio in fats is typically 2:1, meaning there are two hydrogen atoms for every one oxygen atom in the molecule. This ratio is what gives fats their high energy content.
The hydrogen-oxygen ratio in a carbohydrate molecule is typically 2:1, mirroring the ratio found in water (H2O). This means that for every carbon atom in a carbohydrate, there are roughly two hydrogen atoms and one oxygen atom present.
The ratio of hydrogen to oxygen atoms in galactose is 2:1. In the molecular formula of galactose, C6H12O6, there are 12 hydrogen atoms and 6 oxygen atoms.

The ratio of oxygen to hydrogen in a polysaccharide is independent of the type of monosaccharides that it consists of. The ratio does not depend on the number of carbons in the monosaccharide. Thus, for all polysaccharide compounds the ratio of hydrogen to oxygen is 2:1.
Chemical formula for water is H2O. One water molecule has 2 hydrogen atoms. That means 10 hydrogen atoms are needed to form five water molecules.The ration between hydrogen and oxygen in a water molecule is 2:1. In five water molecules, there are five oxygen atoms. According the ratio, there are 10 hydrogen atoms.
The hydrogen-oxygen ratio in a carbohydrate molecule is typically 2:1, mirroring the ratio found in water (H2O). This means that for every carbon atom in a carbohydrate, there are roughly two hydrogen atoms and one oxygen atom present.
The "2" in the formula for water (H2O) indicates that one molecule of water is composed of two hydrogen atoms and one oxygen atom bonded together. It represents the ratio of hydrogen to oxygen atoms in a water molecule.
The ratio of hydrogen to oxygen atoms in galactose is 2:1. In the molecular formula of galactose, C6H12O6, there are 12 hydrogen atoms and 6 oxygen atoms.
In a molecule of ammonia (NH3), which forms when nitrogen and hydrogen combine, the ratio of hydrogen atoms to nitrogen atoms is 3:1.
The formula H2O2 represents hydrogen peroxide, which consists of two hydrogen atoms and two oxygen atoms. The ratio of hydrogen to oxygen atoms is 2:2, indicating that there are equal numbers of each atom in the molecule.
The ratio of hydrogen atoms to oxygen atoms in a molecule of glucose or any other carbohydrate is two hydrogen atoms to one oxygen atom, the same as in water. This is why they are called carbohydrates. This is a fundamental property of carbohydrates.
A water molecule is made of one oxygen atom and two hydrogen atoms, making the correct answer D. This composition gives water its unique properties, essential for life. The molecular formula for water is H₂O, indicating the ratio of hydrogen to oxygen atoms.
