There is no difference between H2O and water. H2O is the chemical formula for water, with each molecule consisting of two hydrogen atoms bonded to one oxygen atom.
Water (H2O) is a chemical compound and iron (Fe) is a chemical element.
carbon dioxide is a gas in the air which we exhale out. water is a liquid which has H2o
The difference between H2O2 and H2O is, H2O is water and is drinkable but H2O2 has a second atom of Oxygen so it is no longer Water or drinkable, because it was chemically changed to Hydrogen Peroxide.
Water has the chemical formula H2O. Acetic acid has the formula CH3COOH.
Sodium chloride is NaCl. Water is H2O.
The abbreviations for centimeters of water are cmH2O and cm H2O. The only difference being a space between the two sets of letters.
Gold molecule is an element. A water molecule is a compund, H2O, composed of two elements
"Pure" water should contain only H2O, however, Carbonated water has carbon dioxide molecules forced into the mix.
Ammonia (NH3) is more polar than water (H2O) due to the electronegativity difference between nitrogen and hydrogen atoms, which leads to a stronger dipole moment in NH3.
Distilled water is only H2O (ideally). Fresh water contains whatever it picks up from the stream bed ... including fish and animal waste.
Hydrogen bonding is strongest in molecules of H2O (water) because oxygen is highly electronegative, creating a large difference in electronegativity between the hydrogen and oxygen atoms which strengthens the hydrogen bonding.
