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
The Hunters in the Snow ice skate, play hockey with modern style sticks and curl on a frozen lake; they are rendered as silhouettes. The 1560s was a time of religious revolution in the Netherlands, and Bruegel (and possibly his patron) may be attempting to portray an ideal of what country life used to be or what they wish it to be.
