Question

2.0 g of a metal burnt in oxygen gave 3.2 g of its oxide. 1.42 g of the same
metal heated in steam gave 2.27 of its
oxide. Which law is verified by these
data ?​

Answer 1

Hey Dear,

◆ Answer -

Law of definite proportion

# Law of definite proportion -

• It states that a given chemical compound always contains its component elements in fixed ratio and does not depend on its source and method of preparation.

● Explanation -

When 2.0 g of metal burns with oxygen, it gives 3.2 g of its oxide.

Ratio of M:O = 2/3.2

Ratio of M:O = 0.625

When 1.42 g of metal is heated with steam, it gives 2.27 g of its oxide.

Ratio of M:O = 1.42/2.27

Ratio of M:O = 0.625

Hence, it is proved that ratio of metal to oxygen in its oxide is same (0.625) irrespective of its method of preparation.

This is called the law of definite proportions.

Thanks dear...

Answer 2

Answer:

law of definet proportion

Explanation:

When 2.0 g of metal burns with oxygen, it gives 3.2 g of its oxide. When 1.42 g of metal is heated with steam, it gives 2.27 g of its oxide. Hence, it is proved that ratio of metal to oxygen in its oxide is same (0.625) irrespective of its method of preparation. This is called the law of definite proportions.
