the chemical formula of water is H2O, so 2 hydrogen atoms and 1 oxygen atoms.

if you have 1 mole of oxygen atoms (O2) and 2 mole of hydrogen atoms (H2) in a test tube then you will form 2 mole of water. uses avagadros number and the mole formula to find out how much of each substance you will form.

What describes the chemical bond of neopentane?

Neopentane, with the chemical formula C5H12, is made up of single covalent bonds between its carbon and hydrogen atoms. The carbon atoms in neopentane are sp3 hybridized, resulting in a tetrahedral molecular shape. These bonds are nonpolar due to the lack of electronegativity difference between carbon and hydrogen.
