The composition is determined by spectral analysis.
you can find info about sea stars at http://www.enchantedlearning.com/subjects/invertebrates/echinoderm/Seastarprintout.shtml
The molecular formula is C20H21FN2O •C2H2O4 and the molecular weight is 414.40. This came up when I was looking for new info on lexapro.
A chemical equation shows a reaction between to chemicals using chemical formulas.
If you look at the nutritional info there is .5 gram trans fat. All butter contains a small amount of trans fat, although its chemical composition is different from industrial trans fats.
The law that provides access to government records with exceptions for records with medical info is the Freedom of Information Act.
For chemical elements the most important factor is the electronegativity.

Yes they do. If you need more info you can check out a website about zodiac signs and their relations with stars.
Explosives are used to study the composition of the Earth. Detonation of a small explosive charge creates a shock wave in the Earth, This is reflected, and the studied reflection provides info on different levels of materials at different depths. See "Seismic studies"
An empirical formula provides the simplest whole-number ratio of the elements in a compound. It does not indicate the actual number of atoms in a molecule or the compound's molecular structure. Instead, it reveals the relative proportions of each element, which can help in understanding the composition of substances in chemical analysis. For example, the empirical formula for hydrogen peroxide (H₂O₂) is HO, indicating a 1:1 ratio of hydrogen to oxygen.
Different colors of stars can tells us the temperature of that star. It can also tell us the luminosity and mass of a star and where it is in its life cycle, whether it is a proto-star (new) or red super giant (dying high mass stars), or white dwarf (dying low mass stars).
