entire world is made up of atoms WWe may not be able to see them, but they are there, and constantly affecting whatever we do. Atems combine in the ratio of small whole numbers to form compounds Calcium carbonate on heating in an endosed vessel decomposes to fom calcium oxide and carbon dioxide. When 10g of calcium carbonate was decomposed completely

then 56 of calcium oxides formed
Which law of chemical combination is used in solving this problems i Law of constant proportions

ii Law of multiple proportions

Law of conservation of mass

iv Law of motion​

Answer 1

Answer:

Law of conservation of mass

Explanation:

In chemistry, the law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.
