How to Get the Diesel Smell Out of Clothes - CAR FROM Dec 24, 2020 · Diesel is a chemical cocktail comprising many ingredients:75% saturated hydrocarbons (primarily paraffins including n, iso, and cycloparaffins), and 25% aromatic hydrocarbons (including naphthalenes and alkylbenzenes). The average chemical formula for common diesel fuel is C 12 H 24, ranging approximately from C 10 H 20 to C 15 H 28. As it contains automatic hydrocarbons, which

Most chemical elements are represented symbolically by two letters, generally the first two in their name. In some cases, the first letter together with some other letter from their name was used, particularly when their first two letters had already been allocated to another element. A very few elements have symbols which appear to have no relationship with their names.
Methasterone C21H34O2 - PubChemMethasterone is a DEA Schedule III controlled substance. Substances in the DEA Schedule III have a potential for abuse less than substances in Schedules I or II and abuse may lead to moderate or low physical dependence or high psychological dependence.
