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)
• yes, because the missing mass was released as smoke
• yes, because the missing mass was trapped by the closed system
•no, because the magnesium was burned so mass was not lost
• no, because mass measured after the experiment decreased
no, because the mass measured after the experiment decreased
The law of conservation of matter states that matter cannot be created or destroyed in a chemical reaction. In this experiment, the magnesium metal was burned and converted to ash, so the mass should remain the same before and after the reaction. The fact that the mass decreased after the experiment indicates that the law of conservation of matter was not followed.
Are you sure explain
I apologize for the unclear explanation. Let me clarify:
In this experiment, Sasha started with 8 grams of magnesium metal and ended up with 5.5 grams of white ash after burning the strip of metal. The fact that the mass decreased from 8 grams to 5.5 grams indicates that some of the magnesium was converted into other products (such as magnesium oxide) and released into the air as smoke or gas. This means that mass was not conserved in the reaction, as some of the initial mass of magnesium metal was lost.
Therefore, this experiment does not demonstrate the law of conservation of matter because the mass measured after the experiment decreased.
Alright!! Good job so what’s the answer
Thank you for the feedback! The answer to the question is:
no, because the mass measured after the experiment decreased
