Which of the following statements is true about ‘Law of conservation of mass”?
- a)If two elements form more than one compound between them, then the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers.
- b)The elements are always present in a constant proportion in a chemical substance.
- c)The rate of reaction is directly proportional to the active mass of the reactants.

Understanding the Law of Conservation of Mass
The Law of Conservation of Mass is a fundamental principle in chemistry that states that matter cannot be created or destroyed in a chemical reaction. This law is crucial for understanding how substances interact during chemical processes.
Key Points:
- Matter is Conserved:
- In any chemical reaction, the total mass of the reactants equals the total mass of the products.
- This means that the atoms present in the reactants are rearranged to form products but are neither lost nor gained.
- Implications of the Law:
- The law emphasizes that during a reaction, the quantity of matter remains constant.
- This has been foundational in developing chemical equations, where the mass of reactants must equal the mass of products.
- Experimental Evidence:
- Numerous experiments conducted by scientists like Antoine Lavoisier demonstrated that when substances react, their total mass before and after the reaction remains unchanged.
- This finding laid the groundwork for modern chemistry and stoichiometry.
Conclusion:
Option 'D' is correct because it encapsulates the essence of the Law of Conservation of Mass. Understanding this principle is vital for comprehending chemical reactions and their applications in various fields of science.
