Sedimentary rocks can contain fossils because, unlike most igneous and metamorphic rocks, they form at temperatures and pressures that do not destroy fossil remains.n that only 10% of the 33% of the rocks contain fossils.

Sodium erythorbate (C 6 H 7 NaO 6) is a food additive used predominantly in meats, poultry, and soft drinks.Chemically, it is the sodium salt of erythorbic acid.When used in processed meat such as hot dogs and beef sticks, it increases the rate at which nitrite reduces to nitric oxide, thus facilitating a faster cure and retaining the pink coloring.n urban myth claims that sodium erythorbate is made from ground earthworms; however, there is no truth to the myth. It is thought that the genesis of the legend comes from the similarity of the chemical name to the words earthworm and bait.
Special Sections. Sodium PCA Sodium PCA, otherwise known as the sodium salt of pyrrolidone carbonic acid, is a humectant that is naturally occurring in the skin. It is a derivative of amino acids that is very water absorbing.It is also hygroscopic, meaning that it absorbs moisture from the air.pecial Sections.
