Question

on heating 4.9 g of kclo3, 1.92g oxygen is evolved and 2.97 g of kcl is obtained as a residue. show that these data illustrate the law of conservation of mass.

please answer the question properly.
​

Answer 1

Answer:

4.9 + 1.92 + 2.97

8.79 = kclo3

8.79 =8.79

Explanation:

law of conservation of mass because the mass kclo3 is equal to the 4.9 ,1.92 , 2.97.

so the data illustrate the law of conservation
