Interpretation: How the matter is conserved in case of burning a piece of paper needs to be explained.
Concept Introduction :
According to law of conservation of matter “matter can neither be created nor be destroyed and it changes from one form to another form.”

Answer to Problem 7E
The total mass of reactants should be equal to the total mass of products.
Explanation of Solution
Combustion is a
Paper is made of wood which is a mixture of hydrocarbons.
On burning of paper, it turns into ash and release some smoke.
Mass of the paper = Mass of ash + mass of smoke released
The mass of released gases cannot be determined but it does not mean that conservation of mass does not take place.
Paper changed from one form to another and there is no loss of matter.
This proves the law of conservation of matter.
