Answer: The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. ... If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.
A) what is the law of conservation of mass?
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation it changed from one to another form.
B) what is an every day example of the law of conservation of mass?
Burning of wood:
When wood is burn it converted into ashes, soot and gases. The mass of all these are equal to the mass of reactants i.e, oxygen and charcoal.
C) how do we see the law of conservation of mass everyday?
Burning of candle:
When candle is burn the mass of wax and oxygen is equal to the product which are carbon dioxide and water. Thus burning of candle also follow the law of conservation of mass.
Burning of wood:
When wood is burn it converted into ashes, soot and gases. The mass of all these are equal to the mass of reactants i.e, oxygen and charcoal.
D) who proposed the theory of the law of conservation of mass?
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
