Answer: Mass is neither lost nor gained during a chemical change.
Explanation:
Antoine Lavoisier’s Law of Conservation of Mass:
'In a chemical reaction the mass can neither be created and nor be destroyed'.
In a chemical reaction the mass of reactants is equal to the mass of products which means that the mass remain conserved.
For Example: In a chemical reaction:
[tex]2H_2+O_2\rightarrow2H_2O[/tex]
Mass of reactants = Mass of products
Mass of hydrogen molecule + mass of oxygen molecule = Mass of water
[tex]2\times (1)(2)+ 1\times (16)(2)= 2\times((1)(2)+(16)(1))=36[/tex]
From this we can see that the mass remains conserved in the chemical reaction.
