4.88 g of $K C l O_{3}$ when heated produced 1.92 g of $O_{2}$ and 2.96 g of KCl. Which of the following statements regarding the experiments is correct?

Options:

Answer:

Solution:

$\underset{4.88 g}{2 K C l O_{3}} \to \underset{2.96 g}{2 K C l} + \underset{1.92 g}{3 O_{2}}$
Since mass of the products (2.96 + 1.92) is equal to the mass of the reactant, this illustrates the law of conservation of mass.
