13. State the law of conservation of mass. State the main points of Landolt's experiments evidence of the law.
Answers
Answer:
Solution: The ‘law of conservation of mass’ says that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. The mass of the products in a chemical reaction must equal the mass of the reactants. ... They were weighed again and the weight was the same as before.
Explanation:
mark me brainlest
Answer:
law of conservation of mass state that mass neither be created nor be destroyed
Main points of Landolt's Experiment were:-
(1) A specially designed H-shaped tube is taken with its one limb having Sodium chloride solution and the other have AgNO
3
. This, in the first place was weighed after sealing.
(2) The reaction was made to take place and then the tube was weighed.
(3) The mass of the tube in both the case was found to be the same. Thus redefining the Law of Conservation of Mass.
