Question

8. One part of an element A combines with two parts of B (Another element). Six parts of element C
combine with four parts of element B. If A and C combine to gether, the ratio of their masses will be
governed by:-
(A) Law of definite proportion
(B) Law of multiple proportion
(C) Law of reciprocal proportion
(D) Law of conservation of mass​

Answer 1

If A and C combine together, the ratio of their masses will be  governed by:-

(C) Law of reciprocal proportion

- According to this law, if two different elements are combining separately with the same mass of a third element, then the ratio of the masses in which they are combining are either the same or a simple multiple of the mass ratio in which they combine.

- As the given elements A, B and C are combining in a simple ratio, so this law will govern the combination of the given elements.
