Question

State law of constant proportions? Illustrate with one
example.​

Answer 1

Explanation:

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:

Here is the answer =>

Explanation:

Law of constant proportion states that in every chemical reaction, the reactants are added or reacted in a fixed ration which is constant for that particular reaction.

eg:-In H2O

H2/O

1(2)/16

2/16

1/8.

Hence in water(H2O) Hydrogen and Oxygen have fixed ratio ,which is 1:8.
