Question

Q2.
a) Define Law of conservation of mass. Explain with the help of example.
b) If we have a pile of wood and set a fire on it the ashes left behind are very least,
what is the reason behind?​

Answer 1

Answer:

The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases, equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.
