Today the laws of definite proportions and multiple proportions, applied to chemical compounds, are considered as not genarally valid.
Many mixtures (not all !) have a fixed composition depending on the specific application and recipe.

Well, I am not a chemist, but I can spell composition. What is meant by "fixed" and whom is composing this nonsensical question?
Explain why the composition of an element is fixed.?
A composition of an element is only fixed if it doesn't radioactively decay, chemically react, interact with a fundamental particle, and no external energy is introduced into the system. These four things happen quite a bit though and if they don't the element stays the same because it is at the lowest energy state it can obtain.
