Question

In compound A, 1.00g of nitrogen unites with
0.57g of oxygen. In compound B, 2.00g of nitrogen
combines with 2.24g of oxygen. In compound C,
3.00g of nitrogen combines with 5.11g of oxygen.
These results obey the following law
(a) law of constant proportion
(b) law of multiple proportion
(c) law of reciprocal proportion
(d) Dalton’s law of partial pressure

Answer 1

Answer:

a is the answer of question

Answer 2

(b) law of multiple proportion

Explanation:

In compound A, 1.00g of nitrogen unites with 0.57g of oxygen. In compound B, 2.00g of nitrogen combines with 2.24g of oxygen. In compound C, 3.00g of nitrogen combines with 5.11g of oxygen.

Ratio of N:O is A = 1 : 0.57

Ratio of N:O is B = 1 : 1.12

Ratio of N:O is C = 3 : 5.11

These results obey the law of multiple proportion.
