• A. Law of definite proportions
• B. Law of conservation of mass
• C. Gay Lussac’s law of combining volumes of gases
• D. Law of multiple proportions

Answer 1

Answer: (D)

The combining ratios of hydrogen and oxygen in water and hydrogen peroxide are $1:8$ and $1:16$. It is an example of law of multiple proportions. According to this law, if two elements combine together to form several compounds then weight of one of these elements, which combines with a fixed weight of the other, are in ratio of simple whole numbers.
