Law of multiple proportions example of the law can be seen by comparing ethane (CH) with propane (CH). The weight of hydrogen which combines with 1 g carbon is 0.252 g in ethane and 0.224 g in propane. The ratio of those weights is 1.125, which can be expressed as the ratio of two small numbers 9:8. The law of multiple proportions is best demonstrated using simple compounds. For example, if one tried to demonstrate it using the hydrocarbons decane (chemical formula CH) and undecane (CH), one would find that 100 grams of carbon could react with 18.46 grams of hydrogen to produce decane
Aventina (given name) Aventina (given name) Aventina () is a Russian female first name. Its masculine version is Aventin. The name was included into various, often handwritten, church calendars throughout the 17th–19th centuries, but was omitted from the official Synodal Menologium at the end of the 19th century.

In 1924–1930, the name was included into various Soviet calendars, which included the new and often artificially created names promoting the new Soviet realities and encouraging the break with the tradition of using the names in the Synodal Menologia. It was rationalized as a form of
