Question

Sasha does an experiment that involves burning an 8 gram strip of magnesium metal in an open flame. After the experiment Sasha measured 5.5 grams of white ash left over after burning the strip of metal. Does this experiment show the law of conservation of matter? (1 point)

Responses
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 released as smoke
yes, because the missing mass was released as smoke
yes, because the missing mass was trapped by the closed system
yes, because the missing mass was trapped by the closed system
no, because mass measured after the experiment decreased

Answer 1

No, because the law of conservation of matter states that matter cannot be created or destroyed, only changed in form. In this experiment, the magnesium was converted into ash and any smoke produced, so the mass was not lost but merely transformed.
