Mariana conducted an experiment where she burned a 5 g strip of magnesium metal in an open flame. The result was a 3.5 g white ash collected in a crucible, a bright white flame, and smoke. Was the law of conservation of matter upheld in Mariana's experiment?
Responses
no, because mass decreased after the magnesium was burned
no, because mass decreased after the magnesium was burned
no, because the magnesium was burned so mass was not lost
no, because the magnesium was burned so mass was not lost
yes, because the missing mass was trapped by the closed system
yes, because the missing mass was trapped by the closed system
yes, because the missing mass was released as smoke
yes, because the missing mass was released as smoke
None of the provided responses correctly address whether the law of conservation of matter was upheld in Mariana's experiment. The correct response would be:
Yes, the law of conservation of matter was upheld in Mariana's experiment because mass is neither created nor destroyed during a chemical reaction. The 5 g of magnesium metal was converted into 3.5 g of white ash, with the remaining mass being released as smoke.
