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
Dora (given name) Dora (given name) Dora () is a female name of Greek origin being a shortened form or derived from Dorothea (Dorothy), Theodora meaning "Gift" or in its full form "God's Gift", from , "doron", "gift" + , "theos", "god".
