what is law of multiple proportion?
Answers
Answer:
In chemistry, the law of multiple proportions states that if two elements form more than one compound between them, then the ratios of the masses of the second element which combine with a fixed mass of the first element will always be ratios of small whole numbers
Answer:
Law of multiple proportions, statement that when two elements combine with each other to form more than one compound, the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers. For example, there are five distinct oxides of nitrogen, and the weights of oxygen in combination with 14 grams of nitrogen are, in increasing order, 8, 16, 24, 32, and 40 grams, or in a ratio of 1, 2, 3, 4, 5. The law was announced (1803) by the English chemist John Dalton, and its confirmation for a wide range of compounds served as the most powerful argument in support of Dalton’s theory
LAW OF MULTIPLE PROPORTIONS - LAW
When two elements combine with each other to form two or more compounds, the ratios of the masses of one element that combines with the fixed ratio of the other are simple whole numbers.
NUMERICAL ON MULTIPLE PROPORTIONS - DEFINITION
For carbon dioxide, 2.66g of oxygen/1.00g of carbon = 2.66. For carbon monoxide, 1.33 g of oxygen/1.00 g of carbon=1.33. The two ratio are in the proportion 2.66/1.33 =2:1.There for the ratio of masses of oxygen that combine with the same mass of carbon is 2:1 i.e. a simple ratio
