Question

Hydrogen combines with oxygen to form two different compounds , namely water and hydrogenperoxide ( a) which law is obeyed by this combination? (B) state the law?

Answer 1

The law obeyed is law of multiple proportions. Let the mass of hydrogen be fixed say 2 g. The mass of oxygen which reacts with the fixed mass of hydrogen is in the ratio of 16 g: 32 g. i.e., 1:2 

Or

It obeys the law of multiple proportion which states that '' when two elements combine to form more than one compound, then one element that combine with a fixed mass of other element is in the ratio of small whole number "

Answer 2

Answer:

The law obeyed here is LAW OF MULTIPLE PROPORTIONS.

Explanation:

It states that if two elements can combine to form more than one compound, the masses of one element that combine with the fixed mass of the other element , are in the ratio of small whole numbers.
