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)
no, because the magnesium was burned so mass was not lost
yes, because the missing mass was trapped by the closed system
no, because mass measured after the experiment decreased
yes, because the missing mass was released as smoke
