In summary, the concept of multiple proportions refers to the relationship between elements in a compound where their masses are in a small whole number ratio. It is determined by analyzing masses of elements in different compounds and is important in stoichiometry. Multiple proportions allow for the prediction of compound properties and can be applied to most compounds, except for some exceptions like polymers. If the ratio of elements in a compound is not a small whole number, it can lead to incorrect predictions and interpretations of its properties.

Doesn't this violate law of multiple proportions?

N2O3 has 2/3 N for every O
NO2 has 1/2 N for every O

(2/3)/(1/2) = 4/3, not a whole number.

It is about proportions in compounds, not proportions of proportions :)

I would say that this does not necessarily violate the law of multiple proportions. The law states that when elements combine to form different compounds, the ratio of their masses will be in small whole numbers. In this case, the ratios of nitrogen to oxygen in N2O3 and NO2 are both small whole numbers (2:3 and 1:2, respectively). The fact that the ratio between these two ratios is not a whole number does not necessarily invalidate the law. It is possible that there are other factors at play, such as the experimental error or the specific conditions under which these compounds were formed. Further research and experimentation would be needed to fully understand the reason for this discrepancy.
 

Related to Multiple proportions incorrect?

1. What is the concept of multiple proportions?

The concept of multiple proportions refers to the relationship between two or more elements in a compound, where the ratio of their masses is always a small whole number. This helps to determine the chemical formula of a compound and is an important concept in stoichiometry.

2. How can multiple proportions be determined?

Multiple proportions can be determined by analyzing the masses of elements in different compounds of the same elements and finding the ratio between them. If the ratio is a small whole number, it indicates a multiple proportion relationship.

3. What is the significance of multiple proportions in chemistry?

Multiple proportions are significant in chemistry because they help to determine the chemical formula of compounds, which is essential in understanding their properties and behaviors. It also allows for the prediction of the masses of elements present in a compound.

4. What happens if the ratio of elements in a compound is not a small whole number?

If the ratio of elements in a compound is not a small whole number, it indicates that the compound is not following the principle of multiple proportions and may have an incorrect formula. This can lead to incorrect predictions and interpretations of the compound's properties.

5. Can multiple proportions be applied to all compounds?

Multiple proportions can be applied to most compounds, but there are some exceptions. Certain compounds, such as polymers, do not follow the principle of multiple proportions because their molecular structure is not based on whole numbers. However, for the majority of compounds, multiple proportions can be applied to determine their chemical formula and properties.
