Answer 2

Question:-

What is law of proportion.Who proposed it?

Solution:-

It was proposed by Proust and verified by Strass and Richards

Definitions:-

• When two elements combine to form a compound they combine in definite proportion
• A chemical compound has same composition by whatever method it was prepared
• Ratio of constituent element by mass is always constant

Examples:-

$c + o_{2} - - > co_{2}$

$co + \frac{1}{2} o_{2} - - > co_{2}$

$caco_{3} - - > cao + co_{2}$

Here, in all cases the ratio of C:O is 3:8
