The mass of one substance in a reaction can be calculated if the masses of the other substances are known. For example: copper carbonate decomposes on heating to make solid copper oxide ...

That’s why the mass stays the same. 4. Show an animation to help explain why mass is conserved in melting, dissolving, and in a chemical change. Show the animation Conservation of Mass in Physical and ...

Lavoisier's finding laid the foundation for modern chemistry and revolutionized science. The Law of Conservation of Mass holds true because naturally occurring elements are very stable at the ...
