Question

write an activity to prove law of conservation of mass​

Answer 1

Answer:

Consider the formation of water molecule. Hydrogen combines with oxygen to form a water molecule. In this case, the total mass of the reactants = total mass of the products. Also, the number of atoms of hydrogen and oxygen in the reactants side and the products side are equal.

Answer 2

The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
