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
Formula restaurant of formula restaurant or formula retail (although non-codified restrictions will sometimes target "chains"). Some chain restaurants are not considered formula restaurants because the chain does not maintain a formulaic or monolithic character at different locations, or has few enough locations that they are substantially dissimilar to what is commonly considered to be a formula restaurant.
