Answer 2

According to law of conservation of mass, mass of a whole object is equal to sum of mass of it's parts.

Explanation:

According of law of mass conservation:

"Mass of any isolated system can neither be created nor destroyed in any chemical process or any physical transformations."

• Law of conservation can be useful in finding out unknown mass components or amount of gas consumed in any reaction.

• In thermodynamics, it can be said that sum of mass of reactants is equal to sum of mass of products.

• Every chemical process obeys this law. Examples are:

1. Photosynthesis process where carbon dioxide and water combines to form oxygen and glucose.
2. Combustion process i.e. burning of wood.
