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 mass measured after the experiment decreased
no, because mass measured after the experiment decreased
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
no, because mass measured after the experiment decreased
why c?
I apologize for the mistake in my response. Option C does not accurately reflect the law of conservation of matter. The correct answer is:
no, because mass measured after the experiment decreased
This is because the mass of the white ash left over after burning the magnesium is less than the initial mass of the magnesium strip. According to the law of conservation of matter, mass cannot be created or destroyed, so the mass should remain constant before and after the experiment.
