Consider the following reacting systems. Which of them correctly describe the application of the Law — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

The Law of Reciprocal Proportions states that if two different elements combine separately with a fixed mass of a third element, the ratio of the masses in which they do so are either the same as or a simple multiple of the ratio of the masses in which they combine with each other. Options A and B describe exactly this scenario involving three interrelated elements (C, H, O and S, H, O respectively). Option C is unrelated. Option D describes the Dulong-Petit Law.
