Question

Activities: Q: According to
law of conservation of mass, the
mass of reactants must be equal
to the mass of products, but we
get very less amount of ash after
burning a heavy wood. Give reason.​

Answer 1

Answer:

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.

Answer 2

Answer:

The law of conservation of mass states the the mass of the reactants and the products during a chemical reaction are same. While burning a heavy wood, some substances present in the wood vaporises in the form of Carbon dioxide (CO2) and thus we get very less amount of ash after burning it. However we can obtain the total mass if we carry out this experiment in a Laboratory by not allowing the CO2 gas to escape.
