Question

100ml of hydrogen combine with 50ml of oxygen to produce water at NTP. under the same condition, 2l of pure hydrogen gas is passed over heated copper oxide. the mass of copper oxide is found to loose it's 1.428 gm. Show that these data illustrate law of constant proportion​

Answer 1

Answer:

your answer

Explanation:

Law of multiple proportions

Law of multiple proportions states that, when two elements combine to form more than one compound, the weights of the combining elements are in a ratio of small whole numbers.

Here, the hydrogen and oxygen combine in a ratio of 2:1

So it is according to the law of multiple proportions and the correct answer is Law of multiple proportions
