Question

experimental verification of the law of conservation of mass

Answer 1

Answer:

In this experiment we shall verify the law of conservation of mass u sing a precipitation reaction. ... Step 2: The physical balance and a watch glass of known mass are used, weigh 7.2 g of BaCl2 . 2H2O and dissolved in a beaker (150 mL) containing 100 mL distilled water. Step 3: Similarly, 16.1 g of Na2SO4

Answer 2

Answer:

Law of conservation of mass states that the mass remains conserved during a chemical reaction . In this experiment we shall verify the law of conservation of mass u sing a precipitation reaction. This reaction is considered as the simplest method to verify this law.
