Explain why sometimes in a lab it seems like the conservation of mass isn’t accurate (but we know we haven't truly lost any mass)

Sagot :

Answer:

The law of conservation of mass states that in a closed system, the whole mass is conserved.

But the law of conservation of mass is not accurate sometimes in lab because in every chemical reaction, mass is converted into energy and not the whole mass can be conserved. Energy in chemical reaction can be created only by destroying the mass and not from any other means.

This is why,  sometimes in a lab it seems like the conservation of mass isn’t accurate.
