Question

One part of an element $A$ combines with two parts of $B$ (another element). Six parts of an element $C$ combine with four parts of an element $B$. If $A$ and $C$ are combined, the ratio of their masses will be governed by:

• A. law of definite proportions
• B. law of multiple proportions
• C. law of reciprocal proportions
• D. law of conservation of mass

Answer 1

The correct option is C law of reciprocal proportions

According to the law of reciprocal proportions, the weights of two elements combining with a fixed amount of the third element will bear the same ratio (or a simple multiple of it) in which they themselves react.
