Camphor chemical formula. Camphor ˈ k æ m f ər is a waxy flammable transparent solid with a strong aroma. It is a terpenoid with the chemical formula C 10 H 16 OIt is found in the wood of the camphor laurel Cinnamomum camphora a large evergreen tree found in East Asia. And in the related kapur tree Dryobalanops sp a tall timber tree from South East AsiaIt also occurs in some other related trees in.
Camphor is a naturally occurring compound that is used as a major active ingredient of balms and liniments supplied as topical analgesics. Capsaicin and menthol two other topically applied agents widely used for similar purposes are known to excite and desensitize sensory nerves by acting on two members of transient receptor potential TRP channel superfamily. The chemical formula for sodium chloride is NaCl indicating that one atom of sodium combines with one atom of chlorine in a one-to-one ratio.
Subscripts are added following the element symbol to indicate that the number of atoms of that element in the compound if it is greater than one. For example the equation for magnesium bromide MgBr2 which indicates that one magnesium atom combines. Chemical formula plays an important role in understanding different concepts of chemistry.
Chemistry is all about learning chemical elements and compounds and how these things work together to form several chemical equations that are hard to understand. A chemical formula shows the symbols of the elements in the compound and the ratio of the elements to one another. Chemical formulas can be.
