Karli Pacheco · Answer 1

Law of definite proportion

Explanation:

As per law of definite proportion, ratio of elements present in a compound is always fixed irrespective of the source, amount and method of preparation.

In the given case, the hydrogen and oxygen react with each other to form a compound. The ratio of oxygen and hydrogen is fixed which is 8 : 1 and this ratio does not change upon changing amount of oxygen and hydrogen.

So, the this experiment support the law of definite proportion.

Therefore, the correct option is option 4
