    Law of conservation of mass is not correct

    for
    A radioactive change Correct Answer Incorrect Answer
    B oxidation Correct Answer Incorrect Answer
    C hydrolysis Correct Answer Incorrect Answer
    D None of the above Correct Answer Incorrect Answer

    Solution

    In radioactive changes, mass is not conserved in the traditional sense as some of the mass is converted into energy according to Einstein’s equation E=mc2E = mc2E=mc2. For other processes like oxidation and hydrolysis, the law of conservation of mass holds true.
