Q. The mass of nitrogen per gram hydrogen in the compound hydrazine is exactly one and half times the mass of nitrogen in the compound ammonia. The fact illustrates the
A) Law of conservation of mass
B) Multiple valency of nitrogen
C) Law of multiple proportions
D) Law of definite proportions
Explanation
(c)
As ratio of masses of nitrogen per gram of hydrogen in hydrazine and $NH_{3}$
$= 1\frac{1}{2}:1$
$= \frac{3}{2}:1$ or 3 : 2
$ie,$ the law of multiple proportions.
