Chemical formula that compound will be made up of the same elements in the same proportion or ratio. For example, any water molecule is always made up of two hydrogen atoms and one oxygen atom in a 2:1 ratio. If we look at the relative masses of oxygen and hydrogen in a water molecule, we see that 94% of the mass of a water molecule is accounted for by oxygen and the remaining 6% is the mass of hydrogen. This mass proportion will be the same for any water molecule. The alkene called but-2-ene has two isomers, which the chemical formula CHCH=CHCH
Edgar Snow was blinded by Chinese hospitality and charm, insisting that "Snow did what he could as a professional journalist." Other historians have been more critical of Snow. Jung Chang and Jon Halliday's biography, "", describes Snow as a Mao spokesman and accuses him of supplying myths, asserting that he lost his objectivity to such an extent that he presented a romanticized view of communist China.
