Question

As a candle burns, it’s mass decreases. However, mass is conserved in this reaction. Explain this observation

Answer 1

There is a law called The Law of Conservation of Mass: this law states that mass can NEVER be created or destroyed. Therefore, mass simply converts into other forms of mass. For example, as a candle burns some of the candle gets coverted into gases such as water vapor and carbon dioxide. All the mass is still there it just changed fram a solid to a gaseous vapor. Make sense?

Answer 2

candle for gaseous product in which the number each of atom is the same to the number of each atom in reactant side
C31H64 +47O2 --->31CO2 +32H2O
The sum of the masses of candle wax+oxygen consumed is the same as masses of CO2 and H20 formed
.According to the law of conservation of mass the sum of the mass of the reagent must be equal to the sum of the mass of the product
