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
Certificate of Formula Compliance Certificate of Formula Compliance A Certificate of Formula Compliance (often abbreviated to COFC) is a document used primarily for Health and Beauty Products in international trade. Unlike a Certificate of Origin (which traditionally states from what country the shipped goods originate, but "originate" in a CO does not mean the country the goods are shipped from, but the country where their goods are actually made.)a COFC is a document that states to the Import Authority that the Products are certified accurate to the Formula that is on record in the Country of Importation.
