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 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 yes, because the missing mass was released as smoke
no, because mass measured after the experiment decreased
Explanation: The law of conservation of matter states that matter cannot be created or destroyed in a chemical reaction, only rearranged. In this case, the mass measured after the experiment decreased, indicating that some of the magnesium was converted into a gas and released into the environment. Therefore, this experiment does not demonstrate the law of conservation of matter.
