Question

Explain in short examples of laws of constant proportions ?​

Answer 1

$\huge{\underline{\sf{\red{ᴀ}\green{ɴ}\pink{s}\orange{ᴡ}\blue{ᴇ}\pink{ʀ}}}}$

The law of constant proportions states that chemical compounds are made up of elements that are present in a fixed ratio by mass. ... For example, in a nitrogen dioxide (NO2) molecule, the ratio of the number of nitrogen and oxygen atoms is 1:2 but the mass ratio is 14:32 (or 7:16).

Answer 2

Answer:

$\huge\underbrace\mathfrak\color{green}Answer$

=>The law of constant proportions states that chemical compounds are made up of elements that are present in a fixed ratio by mass.

=>all samples of that compound will be made up of the same elements in the same proportion or ratio.

Examples:-

=>any water molecule is always made up of two hydrogen atoms and one oxygen atom in a 2:1 ratio.

=>In a nitrogen dioxide (NO2) molecule, the ratio of the number of nitrogen and oxygen atoms is 1:2 but the mass ratio is 14:32 OR 7:16
