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
yes, because the missing mass was trapped by the closed system
yes, because the missing mass was trapped by the closed system
no, because the magnesium was burned so mass was not lost
no, because the magnesium was burned so mass was not lost
no, because mass measured after the experiment decreased
no, because mass measured after the experiment decreased
yes, because the missing mass was released as smoke
no, because mass measured after the experiment decreased
The correct response is "no, because mass measured after the experiment decreased." The law of conservation of matter states that matter cannot be created or destroyed in a closed system, only transformed. In this case, the mass of the magnesium strip decreased from 8 grams to 5.5 grams of ash, indicating that mass was lost during the burning process.
